Hello everyone,
I am trying to record audio & video tracks from multiple RTP
streams(currently only 2 streams) with merged audio(using amix) and stacked
video (hstack).
RTP streams are coming from mediasoup RtpTrasnports that got the
initial streams from webrtc.
Everything works when I'm mixing and mapping only audio(OPUS), but
when I try it with video(VP8) it constantly gets missing keyframe
errors resulting to corrupted files.
ffmpeg args:
-loglevel,debug,-protocol_whitelist,data,rtp,udp,-fflags,+genpts,-f,sdp,-i,data:application/sdp;charset=UTF-8,v=0
o=- 0 0 IN IP4 127.0.0.1
