I'm using beamcoder to save an RTP-OPUS stream into an OGG-OPUS file.
I have an SDP/RTP demuxer that is feeding into an OGG-OPUS muxer. It's using a very simple demuxer.read / muxer.writeFrame loop. It's all working fine, but I'm running into problems shutting it down when I'm done saving.
My first approach was to call demuxer.forceClose to try and unblock the unresolved demuxer.read promise. This, however, is generating a segmentation fault. I suspect it is related to this issue: https://github.com/Streampunk/beamcoder/issues/53 If you'd like, I can provide more debugging information, but it's probably redundant.

interrupt_callback
in the AVFormatContext struct. See https://github.com/FFmpeg/FFmpeg/blob/3da35b7cc7e2f80ca4af89e55fef9a7bcb19c128/libavformat/avformat.h#L1503This would require patching beamcoder. I think it would probably go before
avformat_open_input
is called. Maybe around here: https://github.com/Streampunk/beamcoder/blob/ab226a7aefa0dd1e09de9bc81bff964ee818fb6f/src/demux.cc#L55Could you let me know if I'm on the right path? Is there a better way to close an RTP demuxer early?
Thanks for your help! beamcoder has been a lifesaver!
