I don't know if there are bug reports, but as of r35708, there are
still issues. Now that I'm checking again, this seems to come down to 2
other problems, though: you have to use -demuxer lavf to make some
files work, and changing to 422P is broken.

It's easy enough to create sample files with ffmpeg. Just encode to
multiple resolutions/pixel formats as .mpg, and cat them together.

Anyway, my point stands: as the defaults are broken anyway, I find it
hard to follow the explanation why multithreaded decoding was disabled.
