WebRTC to MKV or hlssink2 - problems with audio+video streams together

[Mandar Joshi]

Hello deim31,
This is just something that popped up in the head when I first saw your
problem. No guarantees it will work but I think it is certainly worth an
attempt.

In the callback to the pad-added signal, audio and video seem to be
arriving one by one and not together.
Can you try creating a common bin starting the bin only after both audio
and video have arrived?

If possible, posting your pad-added callback would certainly help.

Does something apart from hlssink2 work? Like "... ! matroskamux !
filesink" or "... ! matroskamux ! splitmuxsink"
