Commit 10188644 authored by hartman's avatar hartman

* mkv.cpp: retrieve the original framesize from the vobsub idx and store in es_format_t

* vobsub.c: rewrite of the vobsub module. Now has track support. This is UNFINISHED.
  TODO, repair the 'Control' commands store the timestamp/location combo's in the arrays of subtitle_t structs

  and find a way to pass the info from the decoder to the core of course....
