[Question]How can I add a cover to an opus file ? #50

Hi,

How can I add a cover to an opus file ?

fmang commented 3 years ago

I don’t think it’s something specific to Opus, but more like a convention followed by most of Xiph’s formats. See https://wiki.xiph.org/VorbisComment#METADATA_BLOCK_PICTURE

opustags does not generate that tag, but if you dump the base64 data as a regular comment it should work. Note however that opustags does not currently support tags exceeding 64kB.

I saw your question on Stack Overflow (https://superuser.com/questions/1385109/add-album-art-cover-to-an-ogg-opus-file-from-the-command-line). How about trying hackerb9’s answer to generate a recoded Opus with the right tags using opusenc, then reproducing the tags from the recoded file to the original one using opustags? The command for reproducing tags is opustags merged.opus | opustags -S audio.opus -o final.opus. Though that solution is quite wasteful, the result should be just right.

Maybe someday opustags will support cover arts. Someone once hacked opustags for that, see https://github.com/fmang/opustags/pull/21.

@fmang Thanks a lot. I'll look into it.

I'm interested in this as a future option.

This fork had a feature for adding a cover, but it was deleted: https://github.com/zvezdochiot/opustags

I saved the repo though, so there is an example how it can be done.

Oh, thanks for the pointer!

Would it make sense to merge these projects since opustag is active now too? Adding a cover was a really hard to do operation for opus files when last time I tried, until I found that fork.

Opustags writes multi-page meta correct. In libopustag, multi-page metas are written with a small error == warning. But I can't stand C++, so there won't be any merging under any pretext.

My recent works on 1.7.0 for supporting multi-page headers made support for cover arts one step closer. I’ve just added --set-cover and --output-cover in the master branch if anyone would like to try. I will probably release the feature by the end of the month.
