It's a bug in decoder I think, see attached files.

OK, indeed it's a decoding error, probably a regression.

A hunk for decoding of alpha in old huffyuv is misplaced, causing immediate desync on first pixel.
This also probably means a fate test for this is missing.

What's broken in the output? The output file decodes correctly and is similar to the input file as visualized in another program. Should it have been smaller? Is it not lossless?
