Subject: [PATCH] vaapi_decoder/linux: P010 Zero-Copy for VA-API Video Decoding
|
|
for Vulkan
|
|
|
|
This CL adds P010 to the list of renderable formats for Vulkan, enabling
|
|
zero-copy video decoding via VA-API. By avoiding the unnecessary
|
|
conversion from P010 to NV12, this optimization preserves color depth
|
|
and improves overall performance.
|
|
|
|
Test on Ubuntu 22.04 for Alder Lake:
|
|
Linux Ozone-Wayland Vulkan:
|
|
`
|
|
chrome --ignore-gpu-blocklist --disable-gpu-driver-bug-workaround
|
|
--enable-features=Vulkan,VaapiIgnoreDriverChecks,DefaultANGLEVulkan,VulkanFromANGLE
|
|
--use-gl=angle --use-angle=vulkan --ozone-platform=wayland
|
|
`
|
|
|
|
Linux Ozone-X11 Vulkan:
|
|
`
|
|
chrome --ignore-gpu-blocklist --disable-gpu-driver-bug-workaround
|
|
--enable-features=Vulkan,VaapiIgnoreDriverChecks,DefaultANGLEVulkan,VulkanFromANGLE
|
|
--use-gl=angle --use-angle=vulkan --ozone-platform=x11
