[MPlayer-users] mencoder, x264 and freeze

I recently got a new SVN version of mplayer, which needed a fresh git
pull of x264 (which is now libx264.so.79).

After building mencoder, and running the following line, mencoder runs
for about 10 minutes or a bit more, then stops and does nothing, CPU
usage is at 0%, ps ax shows 'Sl+' or 'Sl' as status, nothing else. I
cannot press Ctrl+C, only killing it (with SIGKILL) will terminate
mencoder, SIGTERM (and of course SIGINT) does nothing.

I use the following line:

mencoder infile -o outfile -oac mp3lame -lameopts abr=128 -ovc x264
- -x264encopts bitrate=512:pass=1:turbo=1:threads=8 -vf $scale -srate
44100 -ofps 24


(the 2nd pass would look like this, if it ever came to this:)
mencoder infile -o outfile -oac mp3lame -lameopts abr=128 -ovc x264
- -x264encopts
bitrate=512:subq=6:partitions=all:8x8dct:me=umh:frameref=5:pass=2:threads=8
- -vf $scale -srate 44100 -ofps 24

Two days earlier, I was able to compress a movie this way (I'm doing it
exactly this way for now more than two years), but on the end of the 2nd
pass I got a segmentation error (which now I cannot reproduce since it
freezes on the first pass).

So my question is, if someone experienced something similar with
encoding, and/or if my used options are somewhat outdated and therefore
causing the problem...

On my machine I was usually able to attain a speed of ~230 fps on the
first pass and ~120fps on the 2nd pass, but now I only get 180fps on the
first pass...
