Iirc, mp2 and mp3 are very similar, FFmpeg's mp3 decoder also handles mp2 internally. > In particular, I’m interested if the timecodes for each frame (if it exists) > are stored in that frame, or if the timecodes belonging to a frame somehow > have to be calculated by counting the frames? Do you mean timestamps? Generally, the container provides timestamps, mp2 is a codec. For decoded audio, "counting" seems the right approach. > This is a sub-question of my longer more ffmpeg-specific one, which > unfortunately didn’t get a response: > http://ffmpeg.org/pipermail/libav-user/2018-February/010945.html I don't know the answer, you were using old FFmpeg (which is not supported here) and it looked like "wrong mailing list".
