Hello,<div><br></div><div>I'm going through the same thing. Perhaps we can cooperate - it would be nice to get a nice open-source HowTo to get this working - it is quite a challenge piecing everything together. However, progress is being made and actually on the face of it, it isn't that hard.</div>
<div><br></div><div><div>It isn't a problem with 1.6...</div><div> </div><div>The problem you are having there is that the swscale library isn't being linked in. I had this problem and fixed it but it was long enough now that I have forgotten exactly what I did.</div>
</div><div><br></div><div>But basically, you need to ensure that ffmpeg is built properly, including libavcodec and libswscale, and you are linking all the right libraries with app_transcoder. i.e. in the Makefile you have -lpthread -lavcodec -lswscale as your library flags when linking.</div>
<div><br></div><div>When it is right it kicks up a few warnings, but compiles ok.<br><br></div><div>Andrew</div><div><br><div class="gmail_quote">On Tue, Feb 9, 2010 at 3:16 AM, Pham Quy <span dir="ltr"><<a href="mailto:quyps@vega.com.vn">quyps@vega.com.vn</a>></span> wrote:<br>

<br>
Thank to all your kind reply,<br>
<br>
I downloaded this packages<br>
<a href="http://asteriskvideo.svn.sourceforge.net/viewvc/asteriskvideo/" target="_blank">http://asteriskvideo.svn.sourceforge.net/viewvc/asteriskvideo/</a><br>
<br>
and followed this guide<br>
<br>
<a href="http://asterisk-party.net/index.php/Asterisk_Video_3G_FR" target="_blank">http://asterisk-party.net/index.php/Asterisk_Video_3G_FR</a><br>
<br>
As i understand what i do need is that: installing H324 and AMR in order<br>
to make 3G calls, app_mp4 to playback mp4 video, app_rtsp for video<br>
streaming, app_transcoder to use my webcam.<br>
<br>
Since, I just need to make a video IVVR, or video call with SIP phones,<br>
i just need to buid app_mp4 (to playback), app_rtsp, and app_transcoder,<br>
is that right?<br>
<br>
To make a video call, I successfully build app_rtsp and load into<br>
Asterisk (1.6) but still have some problem with app_transcoder the<br>
message from asterisk as following:<br>
<br>
--------------------------------------<br>
[Feb 9 09:08:23] WARNING[4672]: loader.c:428 load_dynamic_module: Error<br>
loading<br>
'app_transcoder.so': /usr/lib/asterisk/modules/app_transcoder.so:<br>
undefined symbol: sws_scale<br>
[Feb 9 09:08:23] WARNING[4672]: loader.c:781 load_resource: Module<br>
'app_transcoder.so' could not be loaded.<br>
--------------------------------------<br>
<br>
I guess it due to incompatibility of asterisk 1.6, how can I overcome<br>
this problem?<br>
<br>
There is a simple dialplan in the guide<br>
<br>
---------------------------------------------<br>
[default]<br>
exten => 5003.1, Answer ()<br>
exten => 5003, n, RTSP (rtsp: / / <a href="http://192.168.1.1/live.sdp" target="_blank">192.168.1.1/live.sdp</a>)<br>
exten => 5003, n, Hangup ()<br>
---------------------------------------------<br>
<br>
I dont really understand the call RTSP(rtsp://<a href="http://192.168.1.1/live.sdp" target="_blank">192.168.1.1/live.sdp</a>)<br>
what argument should i pass in RTSP()? What is the IP?<br>
<br>
Did i ask to much!!? ;)<br>
<br>
plz help.<br>
