Yes, x264 is default.

No.

Of course, have tested. The only issue I notice is when fps=1/1, it can't work
as expected(too fast). Try to use mplayer as follow:

mplayer -demuxer rawvideo -rawvideo fps=25:w=176:h=144:format=i420 your.yuv

If it works, it means you're not the latest svn source. Try:
svn up
then
svn status
then
svn diff
