    rtmpdump −h

DESCRIPTION

    rtmpdump is a tool for dumping media content streamed over RTMP.

    rtmpdump makes a connection to the specified RTMP server and plays the media specified by the given url. The url should be of the form 

      rtmp[t][e]://hostname[:port][/app[/playpath]]

    Plain rtmp, as well as tunneled and encrypted sessions are supported.

OPTIONS

Network Parameters

    These options define how to connect to the media server.

    −−rtmp −r url
    URL of the server and media content.

    −−host −n hostname
    Overrides the hostname in the RTMP URL.

    −−port −c port
    Overrides the port number in the RTMP URL.

    −−protocol −l number
    Overrides the protocol in the RTMP URL. 
      0 = rtmp
  1 = rtmpt
  2 = rtmpe
  3 = rtmpte
  4 = rtmps
  5 = rtmpts

    −−socks −S host:port
    Use the specified SOCKS4 proxy.

Connection Parameters

    These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt.

    −−app −a app
    Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the app name automatically, so it must be given explicitly using this option.

    −−tcUrl −t url
    URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath.

    −−pageUrl −p url
    URL of the web page in which the media was embedded. By default no value will be sent.

    −−swfUrl −s url
    URL of the SWF player for the media. By default no value will be sent.

    −−flashVer −f version
    Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18".

    −−auth −u string
    An authentication string to be appended to the Connect message. Using this option will append a Boolean TRUE and then the specified string. This option is only used by some particular servers and is deprecated. The more general −−conn option should be used instead.

    −−conn −C type:data
    Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. 
      −C B:1 −C S:authMe −C O:1 −C NN:code:1.23 −C NS:flag:ok −C O:0

Session Parameters

    These options take effect after the Connect request has succeeded.

    −−playpath −y path
    Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option.

    −−playlist −Y
    Issue a set_playlist command before sending the play command. The playlist will just contain the current playpath.

    −−live −v
    Specify that the media is a live stream. No resuming or seeking in live streams is possible.

    −−subscribe −d stream
    Name of live stream to subscribe to. Defaults to playpath.

    −−realtime −R
    Download approximately in realtime, without attempting to speed up via Pause/Unpause commands ("the BUFX hack"). Useful for servers that jump backwards in time at the Unpause command. Resuming and seeking in realtime streams is still possible.

    −−resume −e
    Resume an incomplete RTMP download.

    −−skip −k num
    Skip num keyframes when looking for the last keyframe from which to resume. This may be useful if a regular attempt to resume fails. The default is 0.

    −−start −A num
    Start at num seconds into the stream. Not valid for live streams.

    −−stop −B num
    Stop at num seconds into the stream.

    −−buffer −b num
    Set buffer time to num milliseconds. The default is 36000000.

    −−timeout −m num
    Timeout the session after num seconds without receiving any data from the server. The default is 120.

Security Parameters

    These options handle additional authentication requests from the server.

    −−token −T key
    Key for SecureToken response, used if the server requires SecureToken authentication.

    −−jtv −j JSON
    JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken

    −−swfhash −w hexstring
    SHA256 hash of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the −−swfVfy option below. The hash is 32 bytes, and must be given in hexadecimal. The −−swfsize option must always be used with this option.

    −−swfsize −x num
    Size of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the −−swfVfy option below. The −−swfhash option must always be used with this option.

    −−swfVfy −W url
    URL of the SWF player for this media. This option replaces all three of the −−swfUrl, −−swfhash, and −−swfsize options. When this option is used, the SWF player is retrieved from the specified URL and the hash and size are computed automatically. Also the information is cached in a .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time rtmpdump is run. The .swfinfo file records the URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking.

    −−swfAge −X days
    Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again.

Miscellaneous

    −−flv −o output
    Specify the output file name. If the name is − or is omitted, the stream is written to stdout.

    −−hashes −#
    Display streaming progress with a hash mark for each 1% of progress, instead of a byte counter.

    −−quiet −q
    Suppress all command output.

    −−verbose −V
    Verbose command output.

    −−debug −z
    Debug level output. Extremely verbose, including hex dumps of all packet data.

    −−help −h
    Print a summary of command options.

EXIT STATUS

    0
    Successful program execution.

    1
    Unrecoverable error.

    2
    Incomplete transfer, resuming may get further.

ENVIRONMENT

    HOME
    The value of $HOME is used as the location for the .swfinfo file.

FILES

    $HOME/.swfinfo
    Cache of SWF Verification information

NAME

    rtmpgw − RTMP streaming media gateway

SYNOPSIS

    rtmpgw [−r url] [−n hostname] [−c port] [−l protocol] [−S host:port] [−a app] [−t tcUrl] [−p pageUrl] [−s swfUrl] [−f flashVer] [−u auth] [−C conndata] [−y playpath] [−v] [−d subscription] [−e] [−k skip] [−A start] [−B stop] [−b buffer] [−m timeout] [−T key] [−j JSON] [−w swfHash] [−x swfSize] [−W swfUrl] [−X swfAge] [−D address] [−g port] [−q] [−V] [−z]
    rtmpgw −h

DESCRIPTION

    rtmpgw is a server for streaming media content from RTMP out to HTTP.

    rtmpgw listens for HTTP requests that specify RTMP stream parameters and then returns the RTMP data in the HTTP response. The only valid HTTP request is "GET /" but additional options can be provided in URL-encoded fashion. Options specified on the command line will be used as defaults, which can be overridden by options in the HTTP request.

OPTIONS

Network Parameters

    These options define how to connect to the media server.

    −−rtmp −r url
    URL of the server and media content.

    −−host −n hostname
    Overrides the hostname in the RTMP URL.

    −−port −c port
    Overrides the port number in the RTMP URL.

    −−protocol −l number
    Overrides the protocol in the RTMP URL. 
      0 = rtmp
  1 = rtmpt
  2 = rtmpe
  3 = rtmpte
  4 = rtmps
  5 = rtmpts

    −−socks −S host:port
    Use the specified SOCKS4 proxy.

Connection Parameters

    These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt.

    −−app −a app
    Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the app name automatically, so it must be given explicitly using this option.

    −−tcUrl −t url
    URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath.

    −−pageUrl −p url
    URL of the web page in which the media was embedded. By default no value will be sent.

    −−swfUrl −s url
    URL of the SWF player for the media. By default no value will be sent.

    −−flashVer −f version
    Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18".

    −−auth −u string
    An authentication string to be appended to the Connect message. Using this option will append a Boolean TRUE and then the specified string. This option is only used by some particular servers and is deprecated. The more general −−conn option should be used instead.

    −−conn −C type:data
    Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. 
      −C B:1 −C S:authMe −C O:1 −C NN:code:1.23 −C NS:flag:ok −C O:0

Session Parameters

    These options take effect after the Connect request has succeeded.

    −−playpath −y path
    Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option.

    −−live −v
    Specify that the media is a live stream. No resuming or seeking in live streams is possible.

    −−subscribe −d stream
    Name of live stream to subscribe to. Defaults to playpath.

    −−start −A num
    Start at num seconds into the stream. Not valid for live streams.

    −−stop −B num
    Stop at num seconds into the stream.

    −−buffer −b num
    Set buffer time to num milliseconds. The default is 20000.

    −−timeout −m num
    Timeout the session after num seconds without receiving any data from the server. The default is 120.

Security Parameters

    These options handle additional authentication requests from the server.

    −−token −T key
    Key for SecureToken response, used if the server requires SecureToken authentication.

    −−jtv −j JSON
    JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken

    −−swfhash −w hexstring
    SHA256 hash of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the −−swfVfy option below. The hash is 32 bytes, and must be given in hexadecimal. The −−swfsize option must always be used with this option.

    −−swfsize −x num
    Size of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the −−swfVfy option below. The −−swfhash option must always be used with this option.

    −−swfVfy −W url
    URL of the SWF player for this media. This option replaces all three of the −−swfUrl, −−swfhash, and −−swfsize options. When this option is used, the SWF player is retrieved from the specified URL and the hash and size are computed automatically. Also the information is cached in a .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time rtmpdump is run. The .swfinfo file records the URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking.

    −−swfAge −X days
    Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again.

Miscellaneous

    −−device −D address
    Listener IP address. The default is 0.0.0.0, i.e., any IP address.

    −−sport −g port
    Listener port. The default is 80.

    −−quiet −q
    Suppress all command output.

    −−verbose −V
    Verbose command output.

    −−debug −z
    Debug level output. Extremely verbose, including hex dumps of all packet data.

    −−help −h
    Print a summary of command options.

EXAMPLES

    The HTTP request 
    	GET /?r=rtmp:%2f%2fserver%2fmyapp&y=somefile HTTP/1.0
    is equivalent to the rtrmpdump(1) invocation 
    	rtmpdump −r rtmp://server/myapp −y somefile

    Note that only the shortform (single letter) options are supported.

ENVIRONMENT

    HOME
    The value of $HOME is used as the location for the .swfinfo file.

FILES

    $HOME/.swfinfo
    Cache of SWF Verification information

You can cross-compile for other platforms using the CROSS_COMPILE variable: $ make CROSS_COMPILE=arm-none-linux- INC=-I/my/cross/includes Please read the Makefile to see what other make variables are used. This code also requires you to have OpenSSL and zlib installed. You may optionally use GnuTLS or polarssl instead of OpenSSL if desired. You may also build with just rtmpe support, and no rtmps/https support, by specifying -DNO_SSL in the XDEF macro, e.g. $ make XDEF=-DNO_SSL or $ make CRYPTO=POLARSSL XDEF=-DNO_SSL You may also turn off all crypto support if desired $ make CRYPTO= A shared library is now built by default, in addition to the static library. You can also turn it off if desired $ make SHARED= The rtmpdump programs still link to the static library, regardless. Note that if using OpenSSL, you must have version 0.9.8 or newer. For Polar SSL you must have version 1.0.0 or newer. Credit goes to team boxee for the XBMC RTMP code originally used in RTMPDumper. The current code is based on the XBMC code but rewritten in C by Howard Chu. SWF Verification ---------------- Note: these instructions for manually generating the SWFVerification info are provided only for historical documentation. The software can now generate this info automatically, so it is no longer necessary to run the commands described here. Just use the -W (--swfVfy) option to perform automatic SWFVerification. Download the swf player you want to use for SWFVerification, unzip it using $ flasm -x file.swf It will show the decompressed filesize, use it for --swfsize Now generate the hash $ openssl sha -sha256 -hmac "Genuine Adobe Flash Player 001" file.swf and use the --swfhash "01234..." option to pass it. e.g. $ ./rtmpdump --swfhash "123456..." --swfsize 987... Connect Parameters ------------------ Some servers expect additional custom parameters to be attached to the RTMP connect request. The "--auth" option handles a specific case, where a boolean TRUE followed by the given string are added to the request. Other servers may require completely different parameters, so the new "--conn" option has been added. This option can be set multiple times on the command line, adding one parameter each time. The argument to the option must take the form : where type can be B for boolean, S for string, N for number, and O for object. For booleans the value must be 0 or 1. Also, for objects the value must be 1 to start a new object, or 0 to end the current object. Examples: --conn B:0 --conn S:hello --conn N:3.14159 Named parameters can be specified by prefixing 'N' to the type. Then the name should come next, and finally the value: --conn NB:myflag:1 --conn NS:category:something --conn NN:pi:3.14159 Objects may be added sequentially: -C O:1 -C NB:flag:1 -C NS:status:success -C O:0 -C O:1 -C NN:time:12.30 -C O:0 or nested: -C O:1 -C NS:code:hello -C NO:extra:1 -C NS:data:stuff -C O:0 -C O:0 Building OpenSSL 0.9.8k ----------------------- arm: ./Configure -DL_ENDIAN --prefix=`pwd`/armlibs linux-generic32 Then replace gcc, cc, ar, ranlib in Makefile and crypto/Makefile by arm-linux-* variants and use make && make install_sw win32: Try ./Configure mingw --prefix=`pwd`/win32libs -DL_ENDIAN -DOPENSSL_NO_HW Replace gcc, cc, ... by mingw32-* variants in Makefile and crypto/Makefile make && make install_sw OpenSSL cross-compiling can be a difficult beast. Precompiled OpenSSL binaries for Windows are available on http://www.slproweb.com/products/Win32OpenSSL.html If you're just running a pre-built Windows rtmpdump binary, then all you need is the "Light" installer. If you want to compile rtmpdump yourself, you'll need the full installer. Example Servers --------------- Three different types of servers are also present in this distribution: rtmpsrv - a stub server rtmpsuck - a transparent proxy rtmpgw - an RTMP to HTTP gateway rtmpsrv - Note that this is very incomplete code, and I haven't yet decided whether or not to finish it. It is useful for obtaining all the parameters that a real Flash client would send to an RTMP server, so that they can be used with rtmpdump. The current version now invokes rtmpdump automatically after parsing a client request. rtmpsuck - proxy server. See below... All you need to do is redirect your Flash clients to the machine running this server and it will dump out all the connect / play parameters that the Flash client sent. The simplest way to cause the redirect is by editing /etc/hosts when you know the hostname of the RTMP server, and point it to localhost while running rtmpsrv on your machine. (This approach should work on any OS; on Windows you would edit %SystemRoot%\system32\drivers\etc\hosts.) On Linux you can also use iptables to redirect all outbound RTMP traffic. You need to be running as root in order to use the iptables command. In my original plan I would have the transparent proxy running as a special user (e.g. user "proxy"), and regular Flash clients running as any other user. In that case the proxy would make the connection to the real RTMP server. The iptables rule would look like this: iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner \! --uid-owner proxy \ -j REDIRECT A rule like the above will be needed to use rtmpsuck. Note that you should replace "proxy" in the above command with an account that actually exists on your machine. Using it in this mode takes advantage of the Linux support for IP redirects; in particular it uses a special getsockopt() call to retrieve the original destination address of the connection. That way the proxy can create the real outbound connection without any other help from the user. The equivalent functionality may exist on other OSs but needs more investigation. (Based on reading the BSD ipfw manpage, this rule ought to work on BSD: ipfw add 40 fwd 127.0.0.1,1935 tcp from any to any 1935 not uid proxy Some confirmation from any BSD users would be nice.) (We have a solution for Windows based on a TDI driver; this is known to work on Win2K and WinXP but is assumed to not work on Vista or Win7 as the TDI is no longer used on those OS versions. Also, none of the known solutions are available as freeware.) The rtmpsuck command has only one option: "-z" to turn on debug logging. It listens on port 1935 for RTMP sessions, but you can also redirect other ports to it as needed (read the iptables docs). It first performs an RTMP handshake with the client, then waits for the client to send a connect request. It parses and prints the connect parameters, then makes an outbound connection to the real RTMP server. It performs an RTMP handshake with that server, forwards the connect request, and from that point on it just relays packets back and forth between the two endpoints. It also checks for a few packets that it treats specially: a play packet from the client will get parsed so that the playpath can be displayed. It also handles SWF Verification requests from the server, without forwarding them to the client. (There would be no point, since the response is tied to each session's handshake.) Once the play command is processed, all subsequent audio/video data received from the server will be written to a file, as well as being delivered back to the client. The point of all this, instead of just using a sniffer, is that since rtmpsuck has performed real handshakes with both the client and the server, it can negotiate whatever encryption keys are needed and so record the unencrypted data. rtmpgw - HTTP gateway: this is an HTTP server that accepts requests that consist of rtmpdump parameters. It then connects to the specified RTMP server and returns the retrieved data in the HTTP response. The only valid HTTP request is "GET /" but additional options can be provided in normal URL-encoded fashion. E.g. GET /?r=rtmp:%2f%2fserver%2fmyapp&y=somefile HTTP/1.0 is equivalent the rtmpdump parameters "-r rtmp://server/myapp -y somefile". Note that only the shortform (single letter) rtmpdump options are supported. rtmpdump/thread.h0000644000000000000000000000232312440644353013051 0ustar rootroot/* Thread compatibility glue * Copyright (C) 2009 Howard Chu * * This Program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2, or (at your option) * any later version. * * This Program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. rtmpdump/rtmpgw.80000644000000000000000000001674112440644353013053 0ustar rootroot.TH RTMPGW 8 "2011-07-20" "RTMPDump v2.4" .\" Copyright 2011 Howard Chu. .\" Copying permitted according to the GNU General Public License V2. .SH NAME rtmpgw \- RTMP streaming media gateway .SH SYNOPSIS .B rtmpgw [\c .BI \-r \ url\fR] [\c .BI \-n \ hostname\fR] [\c .BI \-c \ port\fR] [\c .BI \-l \ protocol\fR] [\c .BI \-S \ host:port\fR] [\c .BI \-a \ app\fR] [\c .BI \-t \ tcUrl\fR] [\c .BI \-p \ pageUrl\fR] [\c .BI \-s \ swfUrl\fR] [\c .BI \-f \ flashVer\fR] [\c .BI \-u \ auth\fR] [\c .BI \-C \ conndata\fR] [\c .BI \-y \ playpath\fR] [\c .BR \-v ] [\c .BI \-d \ subscription\fR] [\c .BR \-e ] [\c .BI \-k \ skip\fR] [\c .BI \-A \ start\fR] [\c .BI \-B \ stop\fR] [\c .BI \-b \ buffer\fR] [\c .BI \-m \ timeout\fR] [\c .BI \-T \ key\fR] [\c .BI \-j \ JSON\fR] [\c .BI \-w \ swfHash\fR] [\c .BI \-x \ swfSize\fR] [\c .BI \-W \ swfUrl\fR] [\c .BI \-X \ swfAge\fR] [\c .BI \-D \ address\fR] [\c .BI \-g \ port\fR] [\c .BR \-q ] [\c .BR \-V ] [\c .BR \-z ] .br .B rtmpgw \-h .SH DESCRIPTION .B rtmpgw is a server for streaming media content from RTMP out to HTTP. .LP .B rtmpgw listens for HTTP requests that specify RTMP stream parameters and then returns the RTMP data in the HTTP response. The only valid HTTP request is "GET /" but additional options can be provided in URL-encoded fashion. Options specified on the command line will be used as defaults, which can be overridden by options in the HTTP request. .SH OPTIONS .SS "Network Parameters" These options define how to connect to the media server. .TP \fB\-\-rtmp \-r\fP\ \fIurl\fP URL of the server and media content. .TP \fB\-\-host \-n\fP\ \fIhostname\fP Overrides the hostname in the RTMP URL. .TP \fB\-\-port \-c\fP\ \fIport\fP Overrides the port number in the RTMP URL. .TP \fB\-\-protocol \-l\fP\ \fInumber\fP Overrides the protocol in the RTMP URL. .nf 0 = rtmp 1 = rtmpt 2 = rtmpe 3 = rtmpte 4 = rtmps 5 = rtmpts .fi .TP \fB\-\-socks \-S\fP\ \fIhost:port\fP Use the specified SOCKS4 proxy. .SS "Connection Parameters" These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt. .TP \fB\-\-app \-a\fP\ \fIapp\fP Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the app name automatically, so it must be given explicitly using this option. .TP \fB\-\-tcUrl \-t\fP\ \fIurl\fP URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath. .TP \fB\-\-pageUrl \-p\fP\ \fIurl\fP URL of the web page in which the media was embedded. By default no value will be sent. .TP \fB\-\-swfUrl \-s\fP\ \fIurl\fP URL of the SWF player for the media. By default no value will be sent. .TP \fB\-\-flashVer \-f\fP\ \fIversion\fP Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18". .TP \fB\-\-auth \-u\fP\ \fIstring\fP An authentication string to be appended to the Connect message. Using this option will append a Boolean TRUE and then the specified string. This option is only used by some particular servers and is deprecated. The more general .B \-\-conn option should be used instead. .TP \fB\-\-conn \-C\fP\ \fItype:data\fP Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. .nf \-C B:1 \-C S:authMe \-C O:1 \-C NN:code:1.23 \-C NS:flag:ok \-C O:0 .fi .SS "Session Parameters" These options take effect after the Connect request has succeeded. .TP \fB\-\-playpath \-y\fP\ \fIpath\fP Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option. .TP .B \-\-live \-v Specify that the media is a live stream. No resuming or seeking in live streams is possible. .TP \fB\-\-subscribe \-d\fP\ \fIstream\fP Name of live stream to subscribe to. Defaults to .IR playpath . .TP \fB\-\-start \-A\fP\ \fInum\fP Start at .I num seconds into the stream. Not valid for live streams. .TP \fB\-\-stop \-B\fP\ \fInum\fP Stop at .I num seconds into the stream. .TP \fB\-\-buffer \-b\fP\ \fInum\fP Set buffer time to .I num milliseconds. The default is 20000. .TP \fB\-\-timeout \-m\fP\ \fInum\fP Timeout the session after .I num seconds without receiving any data from the server. The default is 120. .SS "Security Parameters" These options handle additional authentication requests from the server. .TP \fB\-\-token \-T\fP\ \fIkey\fP Key for SecureToken response, used if the server requires SecureToken authentication. .TP \fB\-\-jtv \-j\fP\ \fIJSON\fP JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken .TP \fB\-\-swfhash \-w\fP\ \fIhexstring\fP SHA256 hash of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the .B \-\-swfVfy option below. The hash is 32 bytes, and must be given in hexadecimal. The .B \-\-swfsize option must always be used with this option. .TP \fB\-\-swfsize \-x\fP\ \fInum\fP Size of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the .B \-\-swfVfy option below. The .B \-\-swfhash option must always be used with this option. .TP \fB\-\-swfVfy \-W\fP\ \fIurl\fP URL of the SWF player for this media. This option replaces all three of the .BR \-\-swfUrl , .BR \-\-swfhash , and .B \-\-swfsize options. When this option is used, the SWF player is retrieved from the specified URL and the hash and size are computed automatically. Also the information is cached in a .I .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time rtmpdump is run. The .swfinfo file records the URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking. .TP \fB\-\-swfAge \-X\fP\ \fIdays\fP Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again. .SS Miscellaneous .TP \fB\-\-device \-D\fP\ \fIaddress\fP Listener IP address. The default is 0.0.0.0, i.e., any IP address. .TP \fB\-\-sport \-g\fP\ \fIport\fP Listener port. The default is 80. .TP .B \-\-quiet \-q Suppress all command output. .TP .B \-\-verbose \-V Verbose command output. .TP .B \-\-debug \-z Debug level output. Extremely verbose, including hex dumps of all packet data. .TP .B \-\-help \-h Print a summary of command options. .SH EXAMPLES The HTTP request .nf GET /?r=rtmp:%2f%2fserver%2fmyapp&y=somefile HTTP/1.0 .fi is equivalent to the .BR rtrmpdump (1) invocation .nf rtmpdump \-r rtmp://server/myapp \-y somefile .fi Note that only the shortform (single letter) options are supported. .SH ENVIRONMENT .TP .B HOME The value of .RB $ HOME is used as the location for the .I .swfinfo file. .SH FILES .TP .I $HOME/.swfinfo Cache of SWF Verification information .SH "SEE ALSO" .BR rtmpdump (1) .SH AUTHORS Andrej Stepanchuk, Howard Chu, The Flvstreamer Team .br rtmpdump/ChangeLog0000644000000000000000000002246012440644353013207 0ustar rootrootRTMPDump Copyright 2008-2009 Andrej Stepanchuk; Distributed under the GPL v2 Copyright 2009-2011 Howard Chu Copyright 2009 The Flvstreamer Team http://rtmpdump.mplayerhq.hu/ 20 July 2011 -

fixed endianness - added win32 and arm support (you can cross-compile it onto your Windows box or even PDA) - removed libboost dependency, written a small parser for rtmp urls, but it is more of a heuristic one since the rtmp urls can be ambigous in some circumstances. The best way is to supply all prameters using the override options like --play, --app, etc. - fixed stream ids (from XBMC tree) 19 Jan 2009, v1.3b - fixed segfault on Mac OS/BSDdue to times(0) - Makefile rewritten 16 Jan 2009, v1.3a - fixed a bug introduced in v1.3 (wrong report bytes count), downloads won't hang anymore 10 Jan 2009, v1.3 - fixed audio only streams (rtmpdump now recognizes the stream and writes a correct tag, audio, video, audio+video) - improved resume function to wait till a the seek is executed by the server. The server might send playback data before seeking, so we ignore up to e.g. 50 frames and keep waiting for a keyframe with a timestamp of zero. - nevertheless resuming does not always work since the server sometimes doesn't resend the keyframe, seeking in flash is unreliable 02 Jan 2009, v1.2a - fixed non-standard rtmp urls (including characters + < > ; ) - added small script get_hulu which can download hulu.com streams (US only) (many thanks to Richard Ablewhite for the help with hulu.com) 01 Jan 2009, v1.2: - fixed FLV streams (support for resuming extended) - fixed hanging download at the end - several minor bugfixes - changed parameter behaviour: not supplied parameters are omitted from the connect packet, --auth is introduced (was automatically obtained from url before, but it is possible to have an auth in the tcurl/rtmp url only without an additional encoded string in the connect packet) 28 Dec 2008, v1.1a: - fixed warnings, added -Wall to Makefile 28 Dec 2008, v1.1: - fixed stucking downloads (the buffer time is set to the duration now, so the server doesn't wait till the buffer is emptied - added a --resume option to coninue incomplete downloads - added support for AMF_DATE (experimental, no stream to test so far) - fixed AMF parsing and several small bugs (works on 64bit platforms now) 24 Dec 2008, v1.0: - First release rtmpdump/rtmpsuck.c0000644000000000000000000010262412440644353013452 0ustar rootroot/* RTMP Proxy Server * Copyright (C) 2009 Andrej Stepanchuk * Copyright (C) 2009 Howard Chu * * This Program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2, or (at your option) * any later version. * * This Program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The url should be of the form .nf rtmp[t][e]://hostname[:port][/app[/playpath]] .fi Plain rtmp, as well as tunneled and encrypted sessions are supported. .SH OPTIONS .SS "Network Parameters" These options define how to connect to the media server. .TP \fB\-\-rtmp \-r\fP\ \fIurl\fP URL of the server and media content. .TP \fB\-\-host \-n\fP\ \fIhostname\fP Overrides the hostname in the RTMP URL. .TP \fB\-\-port \-c\fP\ \fIport\fP Overrides the port number in the RTMP URL. .TP \fB\-\-protocol \-l\fP\ \fInumber\fP Overrides the protocol in the RTMP URL. .nf 0 = rtmp 1 = rtmpt 2 = rtmpe 3 = rtmpte 4 = rtmps 5 = rtmpts .fi .TP \fB\-\-socks \-S\fP\ \fIhost:port\fP Use the specified SOCKS4 proxy. .SS "Connection Parameters" These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt. .TP \fB\-\-app \-a\fP\ \fIapp\fP Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the app name automatically, so it must be given explicitly using this option. .TP \fB\-\-tcUrl \-t\fP\ \fIurl\fP URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath. .TP \fB\-\-pageUrl \-p\fP\ \fIurl\fP URL of the web page in which the media was embedded. By default no value will be sent. .TP \fB\-\-swfUrl \-s\fP\ \fIurl\fP URL of the SWF player for the media. By default no value will be sent. .TP \fB\-\-flashVer \-f\fP\ \fIversion\fP Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18". .TP \fB\-\-auth \-u\fP\ \fIstring\fP An authentication string to be appended to the Connect message. Using this option will append a Boolean TRUE and then the specified string. This option is only used by some particular servers and is deprecated. The more general .B \-\-conn option should be used instead. .TP \fB\-\-conn \-C\fP\ \fItype:data\fP Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. .nf \-C B:1 \-C S:authMe \-C O:1 \-C NN:code:1.23 \-C NS:flag:ok \-C O:0 .fi .SS "Session Parameters" These options take effect after the Connect request has succeeded. .TP \fB\-\-playpath \-y\fP\ \fIpath\fP Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option. .TP .B \-\-playlist \-Y Issue a set_playlist command before sending the play command. The playlist will just contain the current playpath. .TP .B \-\-live \-v Specify that the media is a live stream. No resuming or seeking in live streams is possible. .TP \fB\-\-subscribe \-d\fP\ \fIstream\fP Name of live stream to subscribe to. Defaults to .IR playpath . .TP .B \-\-realtime \-R Download approximately in realtime, without attempting to speed up via Pause/Unpause commands ("the BUFX hack"). Useful for servers that jump backwards in time at the Unpause command. Resuming and seeking in realtime streams is still possible. .TP .B \-\-resume \-e Resume an incomplete RTMP download. .TP \fB\-\-skip \-k\fP\ \fInum\fP Skip .I num keyframes when looking for the last keyframe from which to resume. This may be useful if a regular attempt to resume fails. The default is 0. .TP \fB\-\-start \-A\fP\ \fInum\fP Start at .I num seconds into the stream. Not valid for live streams. .TP \fB\-\-stop \-B\fP\ \fInum\fP Stop at .I num seconds into the stream. .TP \fB\-\-buffer \-b\fP\ \fInum\fP Set buffer time to .I num milliseconds. The default is 36000000. .TP \fB\-\-timeout \-m\fP\ \fInum\fP Timeout the session after .I num seconds without receiving any data from the server. The default is 120. .SS "Security Parameters" These options handle additional authentication requests from the server. .TP \fB\-\-token \-T\fP\ \fIkey\fP Key for SecureToken response, used if the server requires SecureToken authentication. .TP \fB\-\-jtv \-j\fP\ \fIJSON\fP JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken .TP \fB\-\-swfhash \-w\fP\ \fIhexstring\fP SHA256 hash of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the .B \-\-swfVfy option below. The hash is 32 bytes, and must be given in hexadecimal. The .B \-\-swfsize option must always be used with this option. .TP \fB\-\-swfsize \-x\fP\ \fInum\fP Size of the decompressed SWF file. This option may be needed if the server uses SWF Verification, but see the .B \-\-swfVfy option below. The .B \-\-swfhash option must always be used with this option. .TP \fB\-\-swfVfy \-W\fP\ \fIurl\fP URL of the SWF player for this media. This option replaces all three of the .BR \-\-swfUrl , .BR \-\-swfhash , and .B \-\-swfsize options. When this option is used, the SWF player is retrieved from the specified URL and the hash and size are computed automatically. Also the information is cached in a .I .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time rtmpdump is run. The .swfinfo file records the URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking. .TP \fB\-\-swfAge \-X\fP\ \fIdays\fP Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again. .SS Miscellaneous .TP \fB\-\-flv \-o\fP\ \fIoutput\fP Specify the output file name. If the name is \- or is omitted, the stream is written to stdout. .TP .B \-\-hashes \-# Display streaming progress with a hash mark for each 1% of progress, instead of a byte counter. .TP .B \-\-quiet \-q Suppress all command output. .TP .B \-\-verbose \-V Verbose command output. .TP .B \-\-debug \-z Debug level output. Extremely verbose, including hex dumps of all packet data. .TP .B \-\-help \-h Print a summary of command options. .SH EXIT STATUS .TP .B 0 Successful program execution. .TP .B 1 Unrecoverable error. .TP .B 2 Incomplete transfer, resuming may get further. .SH ENVIRONMENT .TP .B HOME The value of .RB $ HOME is used as the location for the .I .swfinfo file. .SH FILES .TP .I $HOME/.swfinfo Cache of SWF Verification information .SH "SEE ALSO" .BR rtmpgw (8) .SH AUTHORS Andrej Stepanchuk, Howard Chu, The Flvstreamer Team .br rtmpdump/librtmp/0000755000000000000000000000000012440644353013102 5ustar rootrootrtmpdump/librtmp/amf.c0000644000000000000000000006376712440644353014034 0ustar rootroot/* * Copyright (C) 2005-2008 Team XBMC * http://www.xbmc.org * Copyright (C) 2008-2009 Andrej Stepanchuk * Copyright (C) 2009-2010 Howard Chu * * This file is part of librtmp. * * librtmp is free software; you can redistribute it and/or modify * it under the terms of the GNU Lesser General Public License as * published by the Free Software Foundation; either version 2.1, * or (at your option) any later version. * * librtmp is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

NAME

    librtmp − RTMPDump Real-Time Messaging Protocol API

LIBRARY

    RTMPDump RTMP (librtmp, -lrtmp)

SYNOPSIS

    #include <librtmp/rtmp.h>

DESCRIPTION

    The Real-Time Messaging Protocol (RTMP) is used for streaming multimedia content across a TCP/IP network. This API provides most client functions and a few server functions needed to support RTMP, RTMP tunneled in HTTP (RTMPT), encrypted RTMP (RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled variants of these encrypted types (RTMPTE, RTMPTS). The basic RTMP specification has been published by Adobe but this API was reverse-engineered without use of the Adobe specification. As such, it may deviate from any published specifications but it usually duplicates the actual behavior of the original Adobe clients.

    The RTMPDump software package includes a basic client utility program in rtmpdump(1), some sample servers, and a library used to provide programmatic access to the RTMP protocol. This man page gives an overview of the RTMP library routines. These routines are found in the -lrtmp library. Many other routines are also available, but they are not documented yet.

    The basic interaction is as follows. A session handle is created using RTMP_Alloc() and initialized using RTMP_Init(). All session parameters are provided using RTMP_SetupURL(). The network connection is established using RTMP_Connect(), and then the RTMP session is established using RTMP_ConnectStream(). The stream is read using RTMP_Read(). A client can publish a stream by calling RTMP_EnableWrite() before the RTMP_Connect() call, and then using RTMP_Write() after the session is established. While a stream is playing it may be paused and unpaused using RTMP_Pause(). The stream playback position can be moved using RTMP_Seek(). When RTMP_Read() returns 0 bytes, the stream is complete and may be closed using RTMP_Close(). The session handle is freed using RTMP_Free().

    All data is transferred using FLV format. The basic session requires an RTMP URL. The RTMP URL format is of the form 

      rtmp[t][e|s]://hostname[:port][/app[/playpath]]

    Plain rtmp, as well as tunneled and encrypted sessions are supported.

    Additional options may be specified by appending space-separated key=value pairs to the URL. Special characters in values may need to be escaped to prevent misinterpretation by the option parser. The escape encoding uses a backslash followed by two hexadecimal digits representing the ASCII value of the character. E.g., spaces must be escaped as \20 and backslashes must be escaped as \5c.

OPTIONS

Network Parameters

    These options define how to connect to the media server.

    socks=host:port
    Use the specified SOCKS4 proxy.

Connection Parameters

    These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt.

    app=name
    Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the librtmp URL parser cannot determine the app name automatically, so it must be given explicitly using this option.

    tcUrl=url
    URL of the target stream. Defaults to rtmp[t][e|s]://host[:port]/app.

    pageUrl=url
    URL of the web page in which the media was embedded. By default no value will be sent.

    swfUrl=url
    URL of the SWF player for the media. By default no value will be sent.

    flashVer=version
    Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18".

    conn=type:data
    Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. 
      conn=B:1 conn=S:authMe conn=O:1 conn=NN:code:1.23 conn=NS:flag:ok conn=O:0

Session Parameters

    These options take effect after the Connect request has succeeded.

    playpath=path
    Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option.

    playlist=0|1
    If the value is 1 or TRUE, issue a set_playlist command before sending the play command. The playlist will just contain the current playpath. If the value is 0 or FALSE, the set_playlist command will not be sent. The default is FALSE.

    live=0|1
    Specify that the media is a live stream. No resuming or seeking in live streams is possible.

    subscribe=path
    Name of live stream to subscribe to. Defaults to playpath.

    start=num
    Start at num seconds into the stream. Not valid for live streams.

    stop=num
    Stop at num seconds into the stream.

    buffer=num
    Set buffer time to num milliseconds. The default is 30000.

    timeout=num
    Timeout the session after num seconds without receiving any data from the server. The default is 120.

Security Parameters

    These options handle additional authentication requests from the server.

    token=key
    Key for SecureToken response, used if the server requires SecureToken authentication.

    jtv=JSON
    JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken

    swfVfy=0|1
    If the value is 1 or TRUE, the SWF player is retrieved from the specified swfUrl for performing SWF Verification. The SWF hash and size (used in the verification step) are computed automatically. Also the SWF information is cached in a .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time. The .swfinfo file records the SWF URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking.

    swfAge=days
    Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again.

EXAMPLES

    An example character string suitable for use with RTMP_SetupURL(): 
      "rtmp://flashserver:1935/ondemand/thefile swfUrl=http://flashserver/player.swf swfVfy=1"

ENVIRONMENT

    HOME
    The value of $HOME is used as the location for the .swfinfo file.

FILES

    $HOME/.swfinfo
    Cache of SWF Verification information

In summary, Ping message is used as a special command that are exchanged between client and server. This page aims to document all known Ping messages. Expect the list to grow. The type of Ping packet is 0x4 and contains two mandatory parameters and two optional parameters. The first parameter is the type of Ping and in short integer. The second parameter is the target of the ping. As Ping is always sent in Channel 2 (control channel) and the target object in RTMP header is always 0 which means the Connection object, it's necessary to put an extra parameter to indicate the exact target object the Ping is sent to. The second parameter takes this responsibility. The value has the same meaning as the target object field in RTMP header. (The second value could also be used as other purposes, like RTT Ping/Pong. It is used as the timestamp.) The third and fourth parameters are optional and could be looked upon as the parameter of the Ping packet. Below is an unexhausted list of Ping messages. * type 0: Clear the stream. No third and fourth parameters. The second parameter could be 0. After the connection is established, a Ping 0,0 will be sent from server to client. The message will also be sent to client on the start of Play and in response of a Seek or Pause/Resume request. This Ping tells client to re-calibrate the clock with the timestamp of the next packet server sends. * type 1: Tell the stream to clear the playing buffer. * type 3: Buffer time of the client. The third parameter is the buffer time in millisecond. * type 4: Reset a stream. Used together with type 0 in the case of VOD. Often sent before type 0. * type 6: Ping the client from server. The second parameter is the current time. * type 7: Pong reply from client. The second parameter is the time the server sent with his ping request. * type 26: SWFVerification request * type 27: SWFVerification response */ int RTMP_SendCtrl(RTMP *r, short nType, unsigned int nObject, unsigned int nTime) { RTMPPacket packet;

After the server has sent a complete buffer, and * sends this BufferEmpty message, it will wait until the play * duration of that buffer has passed before sending a new buffer. * The BufferReady message will be sent when the new buffer starts. * (There is no BufferReady message for the very first buffer; * presumably the Stream Begin message is sufficient for that * purpose.) * * If the network speed is much faster than the data bitrate, then * there may be long delays between the end of one buffer and the * start of the next. * * Since usually the network allows data to be sent at * faster than realtime, and rtmpdump wants to download the data * as fast as possible, we use this RTMP_LF_BUFX hack: when we * get the BufferEmpty message, we send a Pause followed by an * Unpause. This causes the server to send the next buffer immediately * instead of waiting for the full duration to elapse. (That's * also the purpose of the ToggleStream function, which rtmpdump * calls if we get a read timeout.) * * Media player apps don't need this hack since they are just * going to play the data in realtime anyway.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This API provides most client functions and a few server functions needed to support RTMP, RTMP tunneled in HTTP (RTMPT), encrypted RTMP (RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled variants of these encrypted types (RTMPTE, RTMPTS). The basic RTMP specification has been published by Adobe but this API was reverse-engineered without use of the Adobe specification. As such, it may deviate from any published specifications but it usually duplicates the actual behavior of the original Adobe clients. The RTMPDump software package includes a basic client utility program in .BR rtmpdump (1), some sample servers, and a library used to provide programmatic access to the RTMP protocol. This man page gives an overview of the RTMP library routines. These routines are found in the -lrtmp library. Many other routines are also available, but they are not documented yet. The basic interaction is as follows. A session handle is created using .BR RTMP_Alloc () and initialized using .BR RTMP_Init (). All session parameters are provided using .BR RTMP_SetupURL (). The network connection is established using .BR RTMP_Connect (), and then the RTMP session is established using .BR RTMP_ConnectStream (). The stream is read using .BR RTMP_Read (). A client can publish a stream by calling .BR RTMP_EnableWrite () before the .BR RTMP_Connect () call, and then using .BR RTMP_Write () after the session is established. While a stream is playing it may be paused and unpaused using .BR RTMP_Pause (). The stream playback position can be moved using .BR RTMP_Seek (). When .BR RTMP_Read () returns 0 bytes, the stream is complete and may be closed using .BR RTMP_Close (). The session handle is freed using .BR RTMP_Free (). All data is transferred using FLV format. The basic session requires an RTMP URL. The RTMP URL format is of the form .nf rtmp[t][e|s]://hostname[:port][/app[/playpath]] .fi Plain rtmp, as well as tunneled and encrypted sessions are supported. Additional options may be specified by appending space-separated key=value pairs to the URL. Special characters in values may need to be escaped to prevent misinterpretation by the option parser. The escape encoding uses a backslash followed by two hexadecimal digits representing the ASCII value of the character. E.g., spaces must be escaped as \fB\\20\fP and backslashes must be escaped as \fB\\5c\fP. .SH OPTIONS .SS "Network Parameters" These options define how to connect to the media server. .TP .BI socks= host:port Use the specified SOCKS4 proxy. .SS "Connection Parameters" These options define the content of the RTMP Connect request packet. If correct values are not provided, the media server will reject the connection attempt. .TP .BI app= name Name of application to connect to on the RTMP server. Overrides the app in the RTMP URL. Sometimes the librtmp URL parser cannot determine the app name automatically, so it must be given explicitly using this option. .TP .BI tcUrl= url URL of the target stream. Defaults to rtmp[t][e|s]://host[:port]/app. .TP .BI pageUrl= url URL of the web page in which the media was embedded. By default no value will be sent. .TP .BI swfUrl= url URL of the SWF player for the media. By default no value will be sent. .TP .BI flashVer= version Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18". .TP .BI conn= type:data Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g. .nf conn=B:1 conn=S:authMe conn=O:1 conn=NN:code:1.23 conn=NS:flag:ok conn=O:0 .fi .SS "Session Parameters" These options take effect after the Connect request has succeeded. .TP .BI playpath= path Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL parser cannot determine the correct playpath automatically, so it must be given explicitly using this option. .TP .BI playlist= 0|1 If the value is 1 or TRUE, issue a set_playlist command before sending the play command. The playlist will just contain the current playpath. If the value is 0 or FALSE, the set_playlist command will not be sent. The default is FALSE. .TP .BI live= 0|1 Specify that the media is a live stream. No resuming or seeking in live streams is possible. .TP .BI subscribe= path Name of live stream to subscribe to. Defaults to .IR playpath . .TP .BI start= num Start at .I num seconds into the stream. Not valid for live streams. .TP .BI stop= num Stop at .I num seconds into the stream. .TP .BI buffer= num Set buffer time to .I num milliseconds. The default is 30000. .TP .BI timeout= num Timeout the session after .I num seconds without receiving any data from the server. The default is 120. .SS "Security Parameters" These options handle additional authentication requests from the server. .TP .BI token= key Key for SecureToken response, used if the server requires SecureToken authentication. .TP .BI jtv= JSON JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken .TP .BI swfVfy= 0|1 If the value is 1 or TRUE, the SWF player is retrieved from the specified .I swfUrl for performing SWF Verification. The SWF hash and size (used in the verification step) are computed automatically. Also the SWF information is cached in a .I .swfinfo file in the user's home directory, so that it doesn't need to be retrieved and recalculated every time. The .swfinfo file records the SWF URL, the time it was fetched, the modification timestamp of the SWF file, its size, and its hash. By default, the cached info will be used for 30 days before re-checking. .TP .BI swfAge= days Specify how many days to use the cached SWF info before re-checking. Use 0 to always check the SWF URL. Note that if the check shows that the SWF file has the same modification timestamp as before, it will not be retrieved again. .SH EXAMPLES An example character string suitable for use with .BR RTMP_SetupURL (): .nf "rtmp://flashserver:1935/ondemand/thefile swfUrl=http://flashserver/player.swf swfVfy=1" .fi .SH ENVIRONMENT .TP .B HOME The value of .RB $ HOME is used as the location for the .I .swfinfo file. .SH FILES .TP .I $HOME/.swfinfo Cache of SWF Verification information .SH "SEE ALSO" .BR rtmpdump (1), .BR rtmpgw (8) .SH AUTHORS Andrej Stepanchuk, Howard Chu, The Flvstreamer Team .br rtmpdump/librtmp/amf.h0000644000000000000000000001276612440644353014032 0ustar rootroot#ifndef __AMF_H__ #define __AMF_H__ /* * Copyright (C) 2005-2008 Team XBMC * http://www.xbmc.org * Copyright (C) 2008-2009 Andrej Stepanchuk * Copyright (C) 2009-2010 Howard Chu * * This file is part of librtmp. * * librtmp is free software; you can redistribute it and/or modify * it under the terms of the GNU Lesser General Public License as * published by the Free Software Foundation; either version 2.1, * or (at your option) any later version. * * librtmp is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
