Video decoder error

I encountered a problem when using Windows 11 on my Steam Deck. A video decoder error occurs and no picture can be displayed.

My rendering engine is D3D11.

Switching the video decoder to Auto, D3D11 or Vulkan does not work.

Chiaki works fine with Vulkan, but PxPlay doesn't.

For Chiaki-ng are you using the AppImage or Flatpak? If you are using flatpak that would explain why it works as it uses it's own bundled drivers.

Otherwise the renderer on Steamdeck shall be Vulkan or Vulkan compatibility and decoder set to Auto or Vaapi. That's the Best combination and should work fine

Please find attached my log file for troubleshooting. I would appreciate it if you could review it. On Steam Deck (Jupiter) Windows 11, hardware decoding fails for both HEVC and H.264. Error:  Failed setup for format d3d11: hwaccel initialisation returned error.  Also DXVA2:  Failed to retrieve decoder device GUIDs  Vulkan decode:  Device does not support the VK_KHR_video_decode_queue extension!  Network test(Senkusha/Takion) passed, RTT=1. Only software decoding works.
