If you notice errors in the align stuff, need more alignment for some ASM code
|
140 |
for some CPU or need to use a function with less aligned data then send a mail
|
141 |
to the ffmpeg-devel mailing list, ...
|
142 |
|
143 |
!warning These alignments might not match reality, (missing attribute((align))
|
144 |
stuff somewhere possible).
|
145 |
I (Michael) did not check them, these are just the alignments which I think
|
146 |
could be reached easily ...
|
147 |
|
148 |
!future video codecs might need functions with less strict alignment
