I have a video stream encoded in H264 video format. The video stream is sent using RTP to the Kurento relay server. From Kurento it is sent to the browser using WebRTC. I adjusted the Kurento configuration in a way, that it prevents transcoding from H264 to VP8 to save CPU resources.
The problem is, that the video sometimes does not show in Firefox (just black screen). It always works in Chrome, in Firefox it appears only in about 30% cases. The data are flowing OK. There is no clear pattern.
I think that it has to do something with the video format (maybe some profile/keyframes/level settings), but by trial and error I was not able to pinpoint the problem.
Is there any way how to get detailed debug information about video decoding in Firefox? I hope there will be some useful information.
