Convert AV1 container file to AV1 bitstream with ffmpeg
I want to extract AV1 bitstream from an AV1 container file(webm, mkv etc). For H264 files this command works:
ffmpeg -i trial.mp4 -c:v copy new.h264
But when same is used for AV1 bitstream:
ffmpeg -i trial.webm -c:v copy new.av1
It throws an error: Unable to find suitable output format for 'new.av1'
I tried vcodec copy as well, and getting the same result. Can anyone help me out in converting Av1 container to bitstream?
Solution 1:
AV1 bitstream can be muxed using the OBU muxer.
ffmpeg -i trial.webm -c:v copy new.obu
