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
|
2011-03-13 22:29:19 +00:00
|
|
|
to the libav-devel mailing list, ...
|
2008-03-10 18:42:09 +00:00
|
|
|
|
|
|
|
!warning These alignments might not match reality, (missing attribute((align))
|
|
|
|
stuff somewhere possible).
|
2008-03-12 23:58:46 +00:00
|
|
|
I (Michael) did not check them, these are just the alignments which I think
|
2008-03-10 18:42:09 +00:00
|
|
|
could be reached easily ...
|
2001-07-22 14:18:56 +00:00
|
|
|
|
2002-09-14 19:00:09 +00:00
|
|
|
!future video codecs might need functions with less strict alignment
