Missing cover image when converting into OGG #23

Open xtemp09 opened 9 years ago

xtemp09 commented 9 years ago

I converted a FLAC into OGG and found that cover art is missing.

The Ogg/Vorbis Encoder (oggenc2.exe) does not offer a way to pass an artwork image – that's why.

Maybe artwork could be added, in a separate step, via vorbiscomment.exe, but I'll have to see ...

Opusenc2 doesn't support art embedding; output APE files lack cover image too. It will require third-party tool(s) to add that feature. Looking through temporary directory, I found that LameXP uses lxp_tag for mp3 metadata.

Might I point at a multifunctional library, like TagLib (http://taglib.github.io), that can kill several birds with one stone?

Nope, 'tag.exe' is used only to embed is only used to emebed ApeTags into Monkey's Audio files. LAME supports adding meta tags to the MP3 it creates files just fine.

Since OggEnc2 doesn't support cover artwork, we could use VorbisComment to add cover artwork to Ogg/Vorbis files. But VorbisComment doesn't provide a way to easily add cover artwork either. It just takes the "raw" data. For cover artwork, we would have to put together a METADATA_BLOCK_PICTURE structure manually. I will have to look into that.
