[x264-devel] --psnr and --dump-yuv

[Étienne Dupuis]

Greetings,

I have noticed that x264 does not output the same PSNR (when using
command line option --psnr) if I use option --dump-yuv or not. I
assume that if --dump-yuv is not set, then x264 does not deblock
frames that are not used as reference.

However, I am inclined to think that if option --psnr is used, x264
should return the correct PSNR and thus deblock all frames. Included
is a patch to encoder.c that should enable deblocking on all frames
when computing PSNR metrics.

Regards,
Étienne
