* avfilter/vf_psnr: use log10 instead of log()/log(10)Ganesh Ajjanagadde2015-10-29
| | | | | | | 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>

* vf_psnr: remove %0.2f format specifiers for stream summary line.Ronald S. Bultje2015-10-22
| | | | This makes output equally precise as vf_ssim.

* vf_psnr: sse2 optimizations for sum-squared-error.Ronald S. Bultje2015-07-14
| | | | | | | | | | | | 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.)

| | | | | | | | 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 255*255*1080*1920 > 2^32).
