oggmeta

oggmeta is a crate that reads .ogg files and decodes the vorbis comments contained within.

Features

oggmeta can read and write vorbis comments and theora comments within ogg files

in case the album art is contained as a theora frame, using theorafile, oggmeta can read the first frame of video and store it as an album cover.

NOTE: that implementation is pretty much completely wrong. ffmpeg does this by default when converting from, for instance, an mp3, but covert art in an ogg file should always be stored in METADATA_BLOCK_IMAGE. However, I don't want oggmeta to overwrite data in an ogg file (besides tags); oggmeta will keep the theora stream, but will exclusively write album covers to METADATA_BLOCK_IMAGE tag.

Limitations

regardless of how much video is in the file, oggmeta will always assume there is only one frame of video and save the first one as an album cover.
