[MEncoder-users] what video output to select for mencoder when encoding dvd's to h.264

[Cristian Manea]

this is the mencoder filters I use:

mencoder vobfile.vob -vf crop=704:464:12:8,yadif,hqdn3d=2:1:2 -nosound -ovc
> x264 -x264encopts
> crf=18.0:preset=slower:tune=film:profile=high:level_idc=30:threads=auto -of
> rawvideo -o encodedstream.264


but even if I open "vobfile.vob" with mplayer, without -vf, without
appending any filter, mplayer stiil outputs "The selected video_out device
is incompatible with this codec", therefore, I don't think it's an error in
the filter chain, maybe it's a ffmpeg problem...
