Comment (by eero-t):
Note: the "A decode call did not consume any data: expect more data at
input" messages in FFmpeg output are there also before PSNR regression,
they are not new.
FYI: When asking FFmpeg to calculate SSIM between the original and
transcoded file instead of PSNR, the regression is ~5%. Performance is
not impacted.
