Those are very strange URLs, don't you think? Seems VLCs SDP parsing is not compatible with PAs SDP generation. Or maybe VLC is just not able to deal with S16BE audio data? I think you should discuss this with the VLC people. (This looks like a VLC issue to me, although I wouldn't rule out that PA is the evildoer here.) > ok. i'll try to modify wireshark to use a audio decoder lib and route > the results to an available audio device ;-) > i played with mplayer, but annot figure out the syntax for the rtp > stream? rtp://225.0.0.1? You should pass the RTP port number as well. PA randomizes the RTP port number on each call (which is a good thing when SAP is used). If you want to use RTP without SAP/SDP you need to use a fixed port number by passing port=46000 or similar to module-rtp-send.
