Ok, I think I tracked down part of the problem: it seems that the
deblocking filter is involved (in ffmpeg, it is disabled by default. In
mencoder and in the x264 CLI, it is enabled). Adding the "-loop" option
to ffmpeg, the quality improves a lot (BTW: are "loop filter" and
"deblocking filter" the same thing?).
Can anyone confirm?
