Are you talking about .cue files? If so, Rockbox already supports those,
and I don't quite understand why you'd want to convert it to bookmarks...

You need access to the file itself, to locate the right position. The
exact method depends on the file format. (And it's complicated enough to
be outside the scope of this mailing list, I'd say. :)

A (pseudo-)random number generator needs a start value, from which
further values are calculated. This is the start value to use, and
controls how the playlist will be shuffled, if shuffle (below) is
enabled. Otherwise it is safe to set to 0.

The minutes and seconds part is easy, just take minutes * 60 + seconds,
then multiply that by 1000. As I don't know what kind of frames you're
talking about, I don't know how to add that.

Source code file. You can see the latest version of it here:

It specifies the state of the shuffle setting when the bookmark was created.
