The frame size of audio codecs is pretty much only dependent on the codec itself, which means you would need to basically hard-code this for every codec you care about. Ultimately I wonder however, when does this information really matter? - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
