Bug#753435: /usr/bin/ghb: Cannot unselect "Burned In" subtitle when output is "MPEG-4 (avformat)"

[Eric Delaunay]

Package: handbrake
Version: 0.9.9+svn6032+dfsg1-2
Severity: normal
File: /usr/bin/ghb

Dear Maintainer,
  when ripping a DVD in MPEG-4 format with including subtitles (VOBSUB tracks),
it is impossible to unselect all "Burned In" radio buttons.
Looking at sources, this restriction seems to come from libhb/common.c,
hb_subtitle_can_pass function, where test "if (source == VOBSUB) return 1"
exists only for HB_MUX_MP4V2.
Don't know why this test cannot be applied to HB_MUX_AV_MP4 (aka libavformat)
too? It is really annoying to always get a subtitle burned in the video track.
Btw, handbrake from Ubuntu supports it due to its linkage against libmp4v2.

I hope you can find a solution to this problem.
Best regards.
Eric.
