Hello,
I got following worrying error when video resolution is not divisible by 8.
Resolutions near that one divisible by 4 resulted in same exception.
This happens at the end of execution, video file seems fine. This error
prevented my 2-pass script from working.
Using only 1 thread results in ordinary Segfault.
