How to set MIME type for cbf embedded in Matroska container?

[bluedan]

Is it already implemented?
I did NOT manage to get it work. I want bsplayer to open embedded cbf file in chapter viewer when I watch the movie.
Anyone successful so far? Could not retrieve a positive post here in the forum.

As matroska is the most powerful container of all existing it would be great if bsplayer would be able to take advantage of all the advanced features that it offers.
Some of it is that you can attach files for which you can define a MIME type, i.e. image/jpg for DVD-cover.jpg being attached.

How do I have to set that type for cbf (chapter images) files IF it is already supported?

I have to refer to this thread as well.
