Hello all!

I have a fairly specific need to output YCbCr, instead of RGB, on the DPI bus for a video playback application. Unfortunately, for my application the DPI output is the only cost effective solution and outboard color space conversion may not be possible. As an experiment I tried specifying hdmi_pixel_encoding as YCbCr Full in config.txt. This didn't seem to work and I knew it was a long shot.

Does anyone know if there's support for YCbCr output on the DPI bus? Alternatively, does anyone know if omxplayer (or similar) is capable of doing a color space conversion prior to output?

Thanks!

OMXPlayer doesn't use frame buffer, that's why your output looked incorrect most likely. You may want to try with other players like VLC or Mplayer.
