[FFmpeg-user] Extracting opus frames from webm/mkv

I have webm files with only opus encoded audio track that I'm streaming
through a voice chat that requires opus encoded packets as input. So far
I've been using ffmpeg to convert the webms with opus audio to ogg
containers and then use my own code to extract opus packets from ogg, which
is obviously inefficient, because webms already contain the very same opus

I would like to extract opus encoded packets so that I can directly serve
them to the voice chat. Is it possible to achieve with ffmpeg cli or any of
its C libraries?

Best regards,
Adam Nowak
