[x264-devel] Mac Quicktime codec

I've been using the x264 codec with great pleasure for some time now for the
european SEMAINE project. To play the x264 encoded videos I prefer to use
mplayer, which always works. However, due to limitations of OpenCv, a
computer vision library, I now have to use Quicktime for decoding. I've
found the x264 Quicktime codec 1.1 on Berlios, which seems to be an inactive
project. Installing it helps, as I know don't get a quicktime error and I
can hear the recorded sound. I do not, however, see anything: it's just
playing black frames.
I used mencoder to encode some low quality videos. This is the line I used
mencoder -o avtracks.avi -audiofile atracks.wav -oac copy -ovc x264 -vf
scale=640:480 -x264encopts subq=4:bframes=2:b_pyramid:weight_b vtracks.avi
Any clues, or pointers to new decoders for quicktime?
