Provide at least one sample file, better more, best a "regular" one
and also some trivial ones (white only, black only, simple patterns,
simple alternating, simple slowly moving patters) to ease development
of a native FFmpeg decoder (of course, if there is or if you can somehow
get a specification for the format even better - though it seems Apple
is far more interested in ensuring vendor-lockin).
