Comparing AVCodecContext.pix_fmt against the get_pixel_format() return
value has the side effect of calling the get_format() callback on each
slice. Users of the callback will probably handle hardware accelerator
initialization in the callback.

They were two very short files that cover ffmpeg-specific features.

Necessary after 04a530f7.

Consider the color space as an hypercone with apex alpha=0
and base alpha=1 instead of an hypercube.
Make the encoder consider very transparent colors more similar
even if the hue is very different.
This corresponds roughly to using the alpha as a weight for the
color difference.
Only 4 bits of alpha are used, because this is what dvdsub uses,
and it avoids overflows.

Fix trac ticket #2005.

Use the first 64 bits of the SHA1 of the content as file UID
instead of a random number if the bitexact flag is set.
