Patch

This is just sad.

As far as I can tell, these files are non compliant. Unfortunately, there are out in the wild (the sample I have is from streaming service) and they decode with both FFmpeg and hardware decoders. So obviously users expect them to play.

Relevant issues in FFmpeg:

Improved patch

VUI if parsing fails at any point after default display window, tries alternative layout (starting with timing information, skipping default display window) which is what FFmpeg seem to do.

Fixes both my sample file and sample file from FFmpeg issue.
