[Bug] VobSub import does not honor origin [sf#187] #187

Open rbouqueau opened 9 years ago

rbouqueau commented 9 years ago

Reported by jeppeoland on 2010-01-02 01:38 UTC When cropping widescreen videos (to not compress the letterbox area), the original subtitle layout is no longer correct.

The IDX file supports specifying an origin. For example:

Origin, relative to the upper-left corner, can be overloaded by aligment

org: 0, 58

MP4Box seems to ignore this value, whereas mkvmerge correctly offsets the subtitle.

Commented by jeppeoland on 2010-01-02 03:51 UTC FWIW, I found a workaround. Applying the inverse offset to the size accomplishes the same thing.

In the previous example, the 720x480 frame size changes to:

Original frame size

size: 720x422

Commented by jeanlf on 2011-07-18 12:47 UTC could you provide a sample vobsub test file for that ?
