Xvid-1.1.3-27042008:
- Plugh pointed me to another bugfix that made it into CVS but wasn't backported to Xvid-1.1.3. There was an issue with motion vectors (MVs), an array was too small so a wrong MV could have been chosen in some cases. Since those MVs are costly bitrate-wise, it should have happened very seldom.


Xvid-1.1.3-12042008:
- Fixes an error that could occur when calling plugins and could result in the wrong frame being passed to a plugin.


Xvid-1.1.3-28062007:
- {core}: Fixed possible security issue in mbcoding.c


Xvid-1.1.2-01112006:

- {core}: Fixed potential crash on AMD64/EMT64 architecture.
- {core}: Fix for visual_object_verid vs. video_object_layer_verid problem.

- On uniprocessor machines set number of threads to 0!


XviD-1.2.-127-07012006

XviD-1.0.3
Changelog:

-MPEG4 compliance is back (beta1 was missing the VOS header)
-matrix quantization is finally thread safe
