Andreas Rheinhardt	8fcc5d963e	avfilter/vf_convolution: Fix build failures `98e419cb` added SIMD for the convolution filter for x64 systems. As usual, it used a check of the form if (ARCH_X86_64) ff_convolution_init_x86(s); and thereby relied on the compiler eliminating this pseudo-runtime check at compiletime for non x64 systems (for which ff_convolution_init_x86 isn't defined) to compile. But vf_convolution.c contains more than one filter and if the convolution filter is disabled, but one of the other filters (prewitt, sobel, roberts) is enabled, the build will fail on x64, because ff_convolution_init_x86 isn't defined in this case.

Ruiling Song	98e419cbf5	avfilter/vf_convolution: add x86 SIMD for filter_3x3() Tested using a simple command (apply edge enhance): ./ffmpeg_g -i ~/Downloads/bbb_sunflower_1080p_30fps_normal.mp4 \ -vf convolution="0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:5:1:1:1:0:128:128:128" \ -an -vframes 1000 -f null /dev/null The fps increase from 151 to 270 on my local machine.

Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
