Theres one on ffmpeg.c rate_emu code, this is valid, its argument is int64_t

This should be reverted at once!

Theres a large number of invalid looking uses in v4l.c. Theres also a
invalid nanosleep in there. Luckily v4l2.c doesnt contain any.
Ill take the liberty to remove the usleeps() together with the whole AIW
support code. Whoever wants it has to clean it up. The code as it is, is
not fit for ffmpeg svn (doing _uneeded_ colorspace convertion in v4l.c).

Theres also one in bktr.c
