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

Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
