picture: align pictures on 64 bytes Code relying on AVX-2 (like dav1d) cannot work without an alignment of 32 bytes at least. Even avcodec has a requirement of 64 (likely to get at least 32 on all planes). So it's probably time to upgrade. picture_Setup ensures a horizontal alignment to 32 bytes and a vertical to 16 bytes. So for all buffers allocated by the core, we have a size multiple of 512 bytes. > http://git.videolan.org/gitweb.cgi/vlc.git/?a=commit;h=0667915e5ad073ca054eb22463d64af400da7ec5 --- src/misc/picture.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/misc/picture.c b/src/misc/picture.c index b373ebd21f..90c6bd7c8d 100644 --- a/src/misc/picture.c +++ b/src/misc/picture.c @@ -73,16 +73,16 @@ static void picture_Destroy(picture_t *pic) VLC_WEAK void *picture_Allocate(int *restrict fdp, size_t size) { - assert((size % 16) == 0); + assert((size % 64) == 0); *fdp = -1; - return aligned_alloc(16, size); + return aligned_alloc(64, size); } VLC_WEAK void picture_Deallocate(int fd, void *base, size_t size) { assert(fd == -1); aligned_free(base); - assert((size % 16) == 0); + assert((size % 64) == 0); } /***************************************************************************** _______________________________________________ vlc-commits mailing list [email protected] https://mailman.videolan.org/listinfo/vlc-commits
