[vlc] Unable to view a video image on YCbCr 4:2:2 video device

Thanks Jean. I have already resolved this issues. but another issues that I
observe that I420_YUY2 module is not implemented for video resizing.

I tried to use the algorithm presented in i420_RGB but it does not work.
can you help me to support video resize for i420_yuy2?

The framebuffer device only outputs RGB atm. I have a similar issue for
another embedded device, but then sending I420 directly to the framebuffer.

Try forcing the Chroma at line 243 of modules/video_output/fb.c
VLC_FOURCC( 'U','Y','V','Y' );

I am still working on it.
