[MEncoder-users] Creating YUV stream suitable for dirac

I'm trying to create a stream in YUV444P, YUV422P or YUV420P suitable
for dirac_encoder or schro_encode. I've tried playing with -of
rawvideo -ovc raw -vf format=444p and -vf format=422p, but after
encoding the stream, the image is correct except for the colospace.
Moreover, I've never been able to play the YUV stream, even with
-demuxer rawvideo -rawvideo w=...:h=...:format=....

Any help is welcome.



PS. Here are the command lines I'm using to encode the video:

$ mencoder -nosound -sws 7 -zoom -vf
crop=720:416:0:80,scale=560:224,format=422p -ovc raw -of rawvideo -o
video-422p.yuv dvd://1
$ dirac_encoder -cformat YUV422P -width 560 -height 224 -fr 25.00
-targetrate 762 video-422p.yuv video-422p.drc

PPS. I'm using MPlayer dev-SVN-r27514-4.1.2
