Hello,
I am experiencing an issue with Shutter Encoder on Arch Linux where the "Hardware acceleration" dropdown menu is greyed out and stuck on "none". I am unable to select Intel QSV, despite it working perfectly on my system.

System Information:

• CPU: Intel Core i5-1235U (12th Gen Alder Lake, featuring Iris Xe Graphics)
• OS: Arch Linux (Dual-boot with Windows 11)
• Shutter Encoder Version: latest version

The Issue:
On Arch Linux, the "Hardware acceleration" option in Shutter Encoder is greyed out and cannot be changed from "none". Therefore, I cannot use Intel QSV to encode. However, on my Windows 11 partition on the exact same machine, the Intel QSV option is available and works flawlessly.

I have verified that this is not a driver or system-level issue on my Linux installation:

1. Drivers are installed: The i915 driver, intel-media-driver, and oneVPL-intel-gpu (required for 12th Gen Intel QSV) are all correctly installed on my Arch Linux.
2. QSV works in other apps: Intel QSV hardware acceleration works perfectly in other Linux applications on my system (e.g., OBS Studio, and when using FFmpeg directly via the terminal with -init_hw_device qsv=hw).
3. VAAPI works: Standard VAAPI acceleration works fine on my system, but Shutter Encoder specifically lacks the QSV option.
4. System FFmpeg fully supports QSV: My Arch Linux FFmpeg is compiled with --enable-libvpl. When I run encoding directly from the terminal using the system FFmpeg, Intel QSV works perfectly and utilizes the iGPU: ffmpeg -i input.mp4 -c:v h264_qsv -global_quality 23 -c:a copy output.mp4 (This encodes at a much higher FPS using the Intel GPU, proving the hardware and drivers are fully functional).
5. Replacing the bundled FFmpeg doesn't fix the UI: I replaced the bundled FFmpeg binary inside Shutter Encoder's directory with my system's FFmpeg (which supports libvpl and QSV). However, the GUI dropdown remained greyed out.

how to fix this?

Thank you for your time and for this great software!
