I get this error when trying to run any video while having vo=gpu-next in my config. If I remove that then the video works but defeats the purpose of the whole thing because you need it for vulkan video decode.

[vo/gpu-next] Failed initializing any suitable GPU context!
Error opening/initializing the selected video_out (--vo) device.
Video: no video

vo=gpu-next is not the problem. I've determined that gpu-api=vulkan is what does not work. I have to get it to gpu-api=opengl to get video output. If I use opengl then I can use vo=gpu-next.

Vulkan video decode working correctly now on my Intel Xe integrated graphics system with h264 and h265 video files after adding the ANV_VIDEO_DECODE=1 variable using flatseal. AV1 files do not yet work but that is expected since it has not yet been fully implemented for the Intel ANV Vulkan driver.

also works with nvidia + wayland using gput-context=waylandvk
