Overlay stream trouble
Able1991 opened this issue · comments
Hi, I experimenting with this demo, sending generally works (a bit confusing how to control the bitrate, but I think I'll find the answer in the mediasoup documentation).
The problem occurred while trying to overlay a stream from mediasoup to another stream (udp, rtmp, etc.).
I understand that this is not a problem with this repository, but perhaps a fresh look and experience with mediaasoup will help localize the problem.
According to ffmpeg logs, it starts working, processes for a while and stops (line 957 of the log file)
I suspect there is something wrong with the stream from mediaasoup

Please don't open a bug report for this. Use the mediasoup public forum for questions or usage problems. BTW your question is about ffmpeg rather than mediasoup ecosystem.
