    Looks like 10bit & 12bit support were added 4 years ago for HEVC https://gitlab.freedesktop.org/vdpau...6327e85add7fa9

      FireBurn Have you tried that in an actual player? Note how the patch you linked to only adds definitions to a header. Meaning it's possible for a driver to advertise support, but that's it. There is no way to actually use 10bit, unless you can point me to a commit that adds 10bit surface support to VDPAU.

      Edit: There's a possibility that the driver has the ability to decode 10bit video to 8bit surfaces, but that means you aren't getting the full 10 bits, but a scaled down result. And I'm not sure even that is supported by players. With VAAPI, you'll get the full 10 bits.

        I believe that's what happens. It decodes 10 bit video but with lower quality output.
