Subject: Re: [PATCH v2 0/4] New DRM properties for output colo
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.
After some discussion, we decided to drop the "active color format"
property and rename the "preferred color format" property to "force
color format".
The user can probe available color formats in combination with other
properties using TEST_ONLY commits.
