AppImage version unable to use hardware decode

[SeeleVolleri]

Describe the bug Moonlight unable to call va_openDriver when Host machine has a different version libva and intel-media-va-driver or i965-va-driver-shaders. tldr: failed to use hardware decode

Steps to reproduce 1, download latest release moonlight-qt AppImage 2, update host libva and intel-media-va-driver and/or i965-va-driver-shaders 3, start streaming and observed a warning shows unable to use hardware decode

Other Moonlight clients

• Does the issue occur when using Moonlight on iOS or Android? No

Moonlight settings (please complete the following information)

• Changed decode setting from auto to Force hardware decode
• The problem still occur after reverting settings back to default.

Client PC details (please complete the following information)

• OS:
• Moonlight Version: v6.0.1 Release

This is unfortunately a side effect of how libva driver versioning works. The version of libva.so must be >= the version of the VA drivers. We use the latest libva version at the time of each Moonlight release, but it will break when your distro's VA drivers are updated to build against a newer libva than Moonlight was.

I recommend avoiding the AppImages if you're on bleeding edge distros, and instead use the Flatpak (which includes compatible libva and VA drivers in the runtime) or another package format that is specific to your distro (like AUR for Arch).
