is the QuickTime @ 1080 this much cpu-hungrier than x264 @ 720? I wonder
a bit.
It is probably not an issue for you, but I still got no answer about how
to encode at the current moment using x264 (a fresh svn from this morning).
All I do is
mencoder input.avi -o output.avi -ovc x264 -oac copy,
and I get the running audio, which resets at every seek (and starts at
0). using -nobps fixes the speed issue, but not the seeking. Any ideas
about this, or any other container suggestion?
