OPUS SDP File

[de_ninja]

Hey,

I'm using opusenc and rtpopuspay in my pipeline and i want to play it with vlc.

This is my SDP File:

v=0
m=audio 5000 RTP/AVP 96
c=IN IP4 192.168.2.255
a=rtpmap:96 OPUS/48000

it worked with my PCMU pipeline (well i used a 0 instead of 96 and PCMU/8000 instead of OPUS/48000)
when i open the stream, vlc tells me:
VLC couldn't identify the Audio- or Videocodec.
Should something else be in the SDP file?
Because i know that VLC supports the Opus codec.

Kind regards

At least with chrome, it only accept "a=rtpmap:96 OPUS/48000/2"
(stereo). Maybe this is what blocks it from working with vlc ?

Check with GStreamer's sdpdemux if you can play back the stream. If
not, check the GStreamer debug logs why not (and fix the SDP
accordingly). If you can, you are probably running into a VLC bug and
should report that to them. Maybe they don't support Opus over RTP yet.

Also see gst-rtsp-server/gst/rtsp-server/rtsp-sdp.c for some code that
allows you to create valid SDP files from GStreamer caps.

I did some test on my own. Work with gst-play-1.0, fails with vlc. For
some reason vlc tries to use PS demux. This is not our bug, the
videolan mailing list would be a better place to get further
assistance.
