Michael Niedermayer	68f328fcdd	avfilter/vf_psnr: avoid 64bit arithmetic in the inner loop Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 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).
