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 ffmpeg-devel mailing list, ...
|
|
|
|
!warning These alignments might not match reality, (missing attribute((align))
|
|
stuff somewhere possible).
|
|
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
