Bug#787086: totem: cuts off subtitles if video stream was trimmed

[Alban Browaeys]

Package: totem
Version: 3.38.0-2
Followup-For: Bug #787086

Dear Maintainer,
I alos have this issue. This seems to only affect subtitle whose stream is sized larged than the video one
 (the subtitle stream is not rescaled to the video one).
This is an upstream issue. I have not yet checked an upstream bug report is submitted.
It may be a gstreamer issue.

That is handbrake trim the black border from the video stream. But the size of the subtitles
 (DVD ones, ie video, not text format) is kept at original video stream size thus larger.
Thuswhy when played back teh subtitles are cut off at the video stream size and only their upper half is shown
(if more than one line of subtitle then nothing is shown).

vlc rescale the subtitle stream to the video one. Thus works. Totem does not.

Cheers,
Alban
