Is there any tool that can edit Opus comments? In particular, I want to add multiple METADATA_BLOCK_PICTURE
s to an Ogg/Opus file.
- opusenc can’t edit comments.
- EasyTag corrupts Ogg files.
- ffmpeg doesn’t support duplicate fields.
All existing answers to my knowledge either only work on Ogg/Vorbis, require re-encoding the audio, or don’t support multiple pictures.
