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
Ganesh Ajjanagadde	59d37f5a4e	avfilter/vf_psnr: use log10 instead of log()/log(10) This is likely more precise and conveys the intent better. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Ronald S. Bultje	ae4c9ddebc	vf_psnr: sse2 optimizations for sum-squared-error. The internal line accumulator for 16bit can overflow, so I changed that from int to uint64_t in the C code. The matching assembly looks a little weird but output looks correct. (avx2 should be trivial to add later.)

Ronald S. Bultje	9879421f1a	vf_psnr: always calculate MSE over full pixel range. This makes the output compatible with that of pretty much any other tool that calculates PSNR. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago

Neil Birkbeck	a11c16a0b0	avfilter/vf_psnr: Prevent integer overflow. The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data. (e.g., for 1080p white frame compared to a black frame can give sum of 2552551080*1920 > 2^32).
