HI Ilya,

a=rtpmap:96 H264/90000

H264 is not supported yet in app_transcoder.

Best regards
Sergio

Hello Sergio

I use:
asterisk-1.4.13
chan_ss7
libh324m (revision 244)
amr ( _http://sip.fontventa.com/_ )
videocodec_nego_fix_ast-1.4.13.patch (
_http://bugs.digium.com/view.php?id=9815_ )

I want to provide video camera to 3G network.
I have a working app_mp4, but *app_transcoder *don't work for me...
Unable to find a codec translation path from unknown to unknown ...

My dialplan:
[incoming-ss7]
exten => 003633379,1,h324m_gw(s@webcamera)
[webcamera]
exten =>
s,1,transcode(,s@camera,h263@qcif/fps=10/kb=52/qmin=4/qmax=12/gs=50)
[camera]
exten => s,1,rtsp(rtsp://192.168.1.49:554/test.sdp)
exten => s,n,HangUp

My test video source
vlc -vvv '/tmp/sample.3gp' --sout
"#transcode{venc=x264,vcodec=x264,width=176,height=144,vb=51,acodec=alaw,ab=8,channels=1,samplerate=8000}:rtp{dst=192.168.1.49,port=554,sdp='rtsp://192.168.1.49:554/test.sdp'}"

One more: amr patch conflicts with videocodec_nego_fix patch near
"[96] = {1, AST_FORMAT_H264}," (main/rtp.c)
