RTMPE Support

[Mirko Puliafito]

RTMPE demuxing seems not to work on current version using native implementation (ffrtmpcrypt)

How to reproduce:

ffmpeg -loglevel debug -probesize 4000 -i rtmpe://127.0.0.1/live/myStream -rtmp_swfverify ​http://127.0.0.1/test.swf -acodec copy -vcodec copy -f flv /home/mirkpul/Scrivania/test_audio.flv

Output:

Please test with

$ ./configure --enable-openssl

or

$ ./configure --enable-gnutls

Generally, you should only use --disable-everything here if you want to report a specific problem about the option, please don't use when reporting missing features (or bugs).

Sorry,

those were my settings. BTW I'm getting the same error with openssl:

Sometimes it also hangs on the "get_packet" just after the "gen_connect" on line 2493 libavformat/rtmpproto.c.

It seems that there's something wrong with the handshake and the server is no more replying to the client.

[Carl Eugen Hoyos]

Which server is this / how can the problem be reproduced?

[Mirko Puliafito]

Flash ui

[Mirko Puliafito]

I tried both with red5 media server:

​http://www.red5.org/red5-server/

and crtmpserver:

​http://www.rtmpd.com/

I used the attached flash app to publish the stream (you need to change the URL to rtmp://127.0.0.1/live and then connect, change the name after Publish video to myStream and then click Publish)

and then try to demux using the provided command.
