Hello I am looking to setup this scenario you discribed below and i am struggling to make it work Did you find a solution for it ? If it is the case, is it possible to share a sample of working code you found ? Thanks in advance. Regards =========================================================== I am trying to learn how to use pjsip with video with pjsip 2.0.1. I don't have a peer/partner to send to so need to use loopback on the PC that runs Ubuntu 10.04 LTS. I am using pjsua like this: pjsua --play-avi=Path_avi_file sip:127.0.0.1 but it is not doing what I imagined it would do. The avi file atworkpcmmulaw8000.avi contains: video: 320x240 ffmpeg mpeg-4 30fps audio: PCM mulaw mono sampling rate 8000 I converted this from a wmv file found at http://www.funny-games.biz/videos/ in section Office Videos under Bored at Work by the ffmpeg utility. There are details about this in another thread 'Cannot get AVI file to play on pjsip 2.0.1' that I will go back to later. Running the command-line command produced a ringtone, but there were points before the ring that I could not understand. 1. I have read PCM mulaw at 8000Hz is widely supported, but the following lines: "18:09:52.335 avi_player.c Unsupported audio stream 18:09:52.335 avi_player.c AVI file player '/home/ken/pjs201c/pjproject-2.0.1/pjsip-apps/bin/atworkpcmmulaw8000.avi' created with 1 media ports 18:09:52.339 pjsua_app.c AVI player atworkpcmmulaw8000.avi created, dev_id=2 18:09:52.339 pjsua_app.c AVI atworkpcmmulaw8000.avi: audio ignored, format=MPG4" seem to indicate it is not supported. Also I am puzzled by 'audio ignored, format=MPG4' since I did not request mpg4 when converting the audio from wmv to avi. 2. The sip INVITE contains SDP that bears no relationship to the audio in the AVI file given in --play-avi option. I imagined pjsip would inspect the avi header and build a corresponding SDP offer because that is what the offerer has got to offer. Can I tell the SIP INVITE to build SDP using the codec info in the avi file from the command-line? Or more generally, how to specify what goes into the SDP part from the command line? 3. Why is the port 0 for video media (video 0 RTP/AVP 31)? since video is needed... 4. Immediately after the UI menu is a message "You have 2 active calls". Why is this? since I have only made one call... 5. a bit further down I can see the message "No pending calls", but I expected one since it was ringing. I tried command-letter a to answer the call, but this did not have any effect. So quit (q) at this point. 6. I also tried some other wmv-to-avi conversions. For example, h.263 for video and audio pcm_s16le, mono,8000hz. Then both video and audio were reported as not supported. Also mystified by this. I really need to understand this a bit better. Hoping for advice. Ken P.S. Here is the console log (probably longer than it needs to be, but could not decide what to leave out): ken at meijin-desktop:~$ ./pjs201c/pjproject-2.0.1/pjsip-apps/bin/pjsua-i686-pc-linux-gnu
