Adding/Embedding fonts in MKV

[quamt]

Hello @rigaya

I want to check if it is possible to add fonts to mkv files, same as mkvtoolnix does when encoding the files? This would be especially helpful for subtitles in ASSformat.

I saw this option --attachment-source but not sure if this can be used for fonts and if yes, what the mimetype would be.

Thank you

I did try --attachment-source "arial.ttf":metadata=mimetype=font/ttf But this errors out with:

Error: Unknown option: font/ttf

Did you mean option(s) below?
  --output
QSVEncC.exe finished with error!

I have added example of using --attachment-source with fonts on the documents.

Thank you @rigaya Will report back.
