None

### Describe the Bug

After system update on Void Linux, sunshine (v2026.516.143833 latest release, AppImage version) cannot init vaapi encoder anymore, leaving me with only software x264 encoder, but i found temporary solution :

1. extract libgallium-26.1.5.so from mesa-libgallium-26.1.5_1.x86_64.tar.zst
2. place symlink at /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so pointing to libgallium-26.1.5.so
3. sunshine vaapi encoder finally works again, after that, no issues

answering question "Is your issue present in the latest beta/pre-release?" - If i use the pre release version, I only see the black screen when connected via moonlight

### Expected Behavior

1. Run ./sunshine.AppImage
2. Lines in log, like :

[2026-08-04 09:18:06.182]: Info: Found H.264 encoder: h264_vaapi [vaapi]
[2026-08-04 09:18:06.182]: Info: Found HEVC encoder: hevc_vaapi [vaapi]
[2026-08-04 09:18:06.182]: Info: Found AV1 encoder: av1_vaapi [vaapi]

and "libva info: Found init function __vaDriverInit_1_22" instead of "Info: /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so has no function __vaDriverInit_1_0"

3. Use

Reproduce the failure with the Sunshine AppImage on Void Linux using Mesa 26.1.6, then inspect the VAAPI/libva initialization log showing the missing driver entry point. Compare it with Mesa 26.1.5, where VAAPI works, and consider the issue complete when the expected VAAPI encoders initialize without the radeonsi error.
