Hi anandapip,
app_transcoder only supports encoding in h263-1998/2000 (h263p), not in
h263-1996.
Best regards

Hi Sergio
Thanks for the reply.
There was a problem in my ffmpeg (livavcodec) which was not buit with
videocodec support.I have replaced it and now not getting the error.
But a strange problem I am facing now.
I have tried transcoding between h263 and h263+.I have used Xlite and
linphone.
I am calling from linphone which is using h263-1998 codec; App
transcoder encodes the incoming h263-1998 to h263 and places call to
xlite. It is also evident from the sip signalling traces that codec
between asterisk and linphone is h263-1998 and between asterisk and
xlite is h263.But if i configure xlite only for h263 ; no video is
apperaing. But if i keep codec in xlite h263-1998 (i.e h263+) video
appears.
I am not sure if app_transcode module is really encoding in h263
format thogh log says it is encoding.
Thanks and regards
Anand

Hi
I want to make video call between two sip phone having different
video codecs using app_transcoder.
I have used the following dialplan
[default]
exten => 101,1,Answer
exten =>
101,2,transcode(,1...@default,h...@qcif/fps=12/kb=52/qmin=4/qmax=12/gs=50)
exten => 102,1,Dial(SIP/101)
the 102 ( having h263-1998 codec) extension is calling 101
(having h263 codec).
I can see the call between the two phone established but no
video; also i dont see any ack coming from 101 and within seconds
asterisk gives a segfault.
Without app transcoder, video call works fine when both phone use
h263-1998 codec.
I am using asterisk 1.4; the transcode module loads succesfully;
even it executes and places a call to the configured extension)
Please help me if i am using the correct dialplan or am i missing
something.
Any help will be much appreciated.
Regards
Anand

Hi
I have successfully compiled and able to load the
app_transcoder.so;
I want to know the configuration of extension.conf to put
the app_transcoder in use.
I have two sip soft phone(video capable) 3000, 3001 which are
already registered to asterisk and I can make audio call
between them;
Also please let me know if i have to add anything specific to
extesion.conf and sip.conf for enabling video call.
Any help will be very much appreciated.
Thanks and regards
