[Asterisk-video] amr sound support for app_rtsp and h324m?

[Sergio Garcia Murillo]

Try making audio packets smaller, as some encoders try to fit as many audio
packets as possible in one rtp frame.

For the video problem also try creating a video with fewer bitrate to see if
it fix the problem.

Best regards
Sergio

I have tested several handsets:

- Sony Ericsson K800i: OK but asynchronous
- Nokia N73: OK but asynchronous
- Nokia N95: audio OK, video very bad (plays but seems to be corrupted)

I am hoping for Sergio as well... ;)

Ok - I will try next week ;-)

Fyi: I played around the last days and managed:
h324m_loopback
h324m_play with helix encoded video (Nokia only, not Sony Ericsson V800)

I guess this is what you achieved too. I'm sure if Sergio is back from
holiday we can make more progress.
