RTMP/RTMPE Support

[insane822]

Reading their mailing list, it looks like they moved to github, so I'm assuming that's now the official repository. If that's the case, the handshake-10 support is unofficial and only available on the branch: https://github.com/svnpenn/rtmpdump/tree/handshake-10.

We'll wait and see, I guess. Thanks for the help.

Not sure that rtmpdump will be updated, since the Adobe company asked SourceForge deleting a protocol implementation hosted on this site (rtmpdump), under the law DMCA3.

I think it only relates to USA, so if the code is hosted in Europe they can't do anything

I have compiled a windows binary with the code that supports shared libraries and everything appears to work perfectly.

Here is my compiled 32-bit windows binary of ffmpeg with handshake-10 support compiled from the code above: https://c388930.ssl.cf1.rackcdn.com/ffm ... mp-2.5.zip

cool, I'll try to build using your rtmpdump sources.

I was looking at this. Currently having issues cross-compiling this, but also the rtmpdump team seems to suggest the Handshake 10 code is illegal, so will not distribute it with 1.0 for now. Users are obviously free to get your builds.

[insane822]

I'm pretty sure if you're in the USA, all versions of rtmpdump would be deemed "illegal", as it's reverse engineering the RTMPE protocol. I won't argue, though.

Just a heads up, the handshake-10 code needs to be compiled on a 32-bit platform if that was causing any issues.

[insane822]

Is there a chance to have the windows build of ffmpeg use a shared librtmp library, so we can just replace the dll with any new versions when needed?

[zip]

not any time soon I think

Right, it's probably missing some additional parameters (swfUrl etc). You should try to do the rtmpserv trick linked in the plugin dev guide - basically pretending your PC is the rtmp server, the player will send rtmp request to it and you'll be able to see the parameters thay are using.

Do you refer to the link http://stream-recorder.com/forum/tutori ... #post18142 ?

I tried that link and allways got sent back to the forums front page. However, I just did a search and found this page

http://stream-recorder.com/forum/tutori ... t6325.html

which works (and is obviously the thread you refer to). So maybe you should drop the "?p=18142#post18142" from the link in the .pdf

Troubleshooting tip I discovered with regards to RTMP.
I am working on an ABC (Australia) iView plugin and I have commands that work to download a stream using RTMPDump. This command works to download the video (if you get a new auth string from the server before you run it).

  Code:

 rtmpdump --rtmp rtmp://cp53909.edgefcs.net:1935 --app 'ondemand?auth=daEc1aMaUa8dicCbYcKcmcSbda5cfaZb3b5-bqnQIz-8-mkt_xErqN&aifp=v001' --playpath mp4:flash/playback/_definst_/drwhoconfidential_06_07 --swfUrl http://www.abc.net.au/iview/images/iview.jpg --swfVfy 1 --swfsize 2122 --swfhash 96cc76f1d5385fb5cda6e2ce5c73323a399043d0bb6c687edd807e5c73c42b37 -o /home/god/Videos/drwho_confid2.mp4


I then tried to use these commands in my plugin. But my plugin would report the following to the logs

  Code:

2012-08-24 08:07:29,473 DEBUG [FFMPEGWrapper] Invoking FFMPEG to retrieve media information for file: rtmp://cp53909.edgefcs.net:1935 app=ondemand?auth=daEdXdUcKbibqc1amcEcDdacDcwcidoana8-bqnQMC-8-snr_xFzoL&aifp=v001 playpath=mp4:flash/playback/_definst_/drwhoconfidential_06_07 swfUrl=http://www.abc.net.au/iview/images/iview.jpg swfVfy=1 swfsize=2122 swfhash=96cc76f1d5385fb5cda6e2ce5c73323a399043d0bb6c687edd807e5c73c42b37

It might not play.
java.io.IOException: org.serviio.library.local.metadata.extractor.InvalidMediaFormatException: Unknown video file type.


and if I ran the ffmpeg -i command from the logs it would just sit there and do nothing.

What I figured out is that I need a command of the form

rtmp://<server>:<port>/<app> playpath=<playpath>

The part of my rtmpdump that was the --app parameter goes after the port number prefixed with slash. And the playpath is specified with a playpath=parameter.
And I did not need any of the rest of the swfUrl, swfVfy, swfsize, swfhash stuff. (See edit below)

  Code:

ffmpeg -i "rtmp://cp53909.edgefcs.net:1935/ondemand?auth=daEcnaKdQaocedWbKa1cycda5dyc9dbd4aZ-bqoINR-8-mkr_tEvpJ&aifp=v001 playpath=mp4:flash/playback/_definst_/drwhoconfidential_06_07"


returns something like

At least one output file must be specified



Which is success. We dont care about "At least one output file must be specified" because we are just getting the metadata with this command. And Ignoring SWFVerification request does not seem to matter.

Edit: Ignoring SWFVerification does matter. If this services does not complete SWFVerification the video stops playing after about a minute. See this thread for my battle with SWFVerification on iView.

I do need a swfUrl and a swfVfy (but not swfsize swfhash)

For playing RTMP streams, Serviio uses ffmpeg containing the standard librtmp support. This does not include key features such as redirect which allows domain names instead of server ips, and other features supported by modified rtmpdump/librtmp such as that provided by KSV. In the absence of an ffmpeg compiled with the modified librtmp, I have successfully used an ffmpeg.bat to invoke a modified rtmpdump for rtmp streams and pipe the output to serviios ffmpeg for DLNA streaming. Given the advantages I will be making this a prerequisite for using my plugins once it has been fully tested.

to compile your own ffmeg with the right rtmpdump and dependencies you can try this method
