I'm using the HDMI output through the framebuffer device on the i.MX6QP.
I have a YUV422 video source and I'd like to emit it on the HDMI without conversion. HDMI 1.4 supports YUV422 pixel encoding.
As for now, the HDMI always outputs a RGB444 stream.
I've tried setting fb_var_screeninfo.nonstd before passing it to ioctl(FBIOPUT_VSCREENINFO), but it seems that any non-zero value provokes the ioctl to fail.
I've also tried giving the kernel argument "mxcfb1:dev=hdmi,1920x1080M@60,if=UYVY16", but it doesn't change anything.
Thanks for your help.
