The basic format is shared with Vorbis, but the 'magic signature' is different ('OpusTags' instead of '0x05vorbis') and vorbis puts a 0x01 value in an extra byte after the last tag. The OpusTag packet layout is described in

For example, these tags are created by default on my files: ENCODER=opusenc from opus-tools 0.2 ENCODER_OPTIONS=--bitrate 6 --comp 10 --framesize 60 --padding 0 I've tried using `--discard-comments` but that has no effect. I've tried using `--comment ENCODER=` but that adds a duplicate tag. My limited knowledge of C suggests that the following lines in opusenc.c are where the magic happens: https:/...
