if u notice errors in the align stuff, need more alignment for some asm code for some cpu
|
2002-09-14 22:00:09 +03:00
|
|
|
or need to use a function with less aligned data then send a mail to the ffmpeg-dev list, ...
|
|
|
|
|
|
|
|
!warning these alignments might not match reallity, (missing attribute((align)) stuff somewhere possible)
|
|
|
|
i (michael) didnt check them, these are just the alignents which i think could be reached easily ...

!future video codecs might need functions with less strict alignment
