Hi Andri, I've made this patch, but I'm unable to configure the video pipeline for YCC 420. I'm using libdrm's modetest to set the output format / colorspace and pass a test pattern through. Modetest can see the new "force output format" property, but it's being rejected and falls back to RGB. I verified my EDID has support for YCC 420. Can you tell me how you're testing this change?
Here's my modetest command: modetest -s 185:3840x2160-60@NV12 -w "185:force color format:8" Thanks, Sean
