Observed Behavior

Tried to play an mp3 stream and CasparCG gets into a fatal exception and quits

Expected behaviour

The stream would start or, if it cannot, at least keeps running.

Steps to reproduce

The error does not happen each time, but when it is, it is playing an mp3 stream

Environment

leftearsons commented 2 months ago

I have also faced multiple cases with Fatal errors causing CasparCG to crash, which seem to be related to unhandled ffmpeg errors.
@Julusian, Do all ffmpeg errors cause CasparCG to exit with a fatal error?

Below are the logs from some related examples i have (also related to ffmpeg audio (aac codec) like the mp3 case above) :

If this is the case (unhandled ffmpeg errors causing CasparCG to crash), wouldn't it make sense to just kill the related producer/consumer when such an internal ffmpeg error occurs?
