<div>Hi Sergio</div>
<div>Thanks for the reply.</div>
<div>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.</div>
<div>But a strange problem I am facing now.</div>
<div>I have tried transcoding between h263 and h263+.I have used Xlite and linphone.</div>
<div>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.</div>
<div>I am not sure if app_transcode module is really encoding in h263 format thogh log says it is encoding.</div>
<div> </div>
<div>Thanks and regards</div>

<div>Hi</div>
<div>I want to make video call between two sip phone having different video codecs using app_transcoder.</div>
<div>I have used the following dialplan</div>
<div>[default]<br>exten => 101,1,Answer<br>exten => 101,2,transcode(,102@default,h263@qcif/fps=12/kb=52/qmin=4/qmax=12/gs=50)<br>exten => 102,1,Dial(SIP/101)</div>
<div> </div>
<div>the 102 ( having h263-1998 codec) extension is calling 101 (having h263 codec).</div>
<div>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.</div>
<div>Without app transcoder, video call works fine when both phone use h263-1998 codec.</div>
<div>I am using asterisk 1.4; the transcode module loads succesfully; even it executes and places a call to the configured extension)</div>
<div> </div>
<div>Please help me if i am using the correct dialplan or am i missing something.</div>
<div> </div>
<div>Any help will be much appreciated.</div>
<div> </div>
<div>Regards</div>
