These decoders use a special non-MPEG2 IDCT. Call it directly instead of going through dsputil. There is never any reason to use a regular IDCT with these decoders or to use the EA IDCT with other codecs. This also fixes the bizarre situation of eamad and eatqi decoding incorrectly if eatgq is disabled. Signed-off-by: Mans Rullgard <mans@mansr.com>

If you notice errors in the align stuff, need more alignment for some ASM code

for some CPU or need to use a function with less aligned data then send a mail

to the libav-devel mailing list, ...

!warning These alignments might not match reality, (missing attribute((align))

I (Michael) did not check them, these are just the alignments which I think

could be reached easily ...

!future video codecs might need functions with less strict alignment
