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 ________________________________ From: Sean Summers <[email protected]> Sent: Wednesday, May 28, 2025 10:23 AM To: [email protected] <[email protected]> Cc: [email protected] <[email protected]>; [email protected] <[email protected]> Subject: Re: [PATCH v2 0/4] New DRM properties for output color format Hi Andri, I've made this patch, but I'm unable to configure the video pipeline for YCC 420.
