[MPlayer-users] encoding speed of x264 major change

My old x264 libs were from ~1 year ago, and until this week, mencoder
used them. Now, on a new checkout of mplayer, x264 wasn't recognized
anymore, so I got a new x264 checkout (now with git), compiled and
installed, and mplayer finds it again in the configure step, but still
the encoding speed is about 1/3rd of the previous speed, with all the
same settings.

I usually do a 2-pass encoding using the following options:


mencoder "$1" -o "$2" -oac mp3lame -lameopts abr=128 -ovc x264
- -x264encopts bitrate=512:pass=1:turbo=1:threads=4

mencoder "$1" -o "$2" -oac mp3lame -lameopts abr=128 -ovc x264
- -x264encopts
bitrate=512:subq=6:partitions=all:8x8dct:me=umh:frameref=5:pass=2:threads=4

which delivers ~120-150 fps on the first pass, and 30~40 fps on the
second pass. Now, the new version has 50fps on the first and 10 on the
second...
