Emby bundles its VA-API drivers (iHD, i965, radeonsi, etc.) under /app/emby/lib/dri on the beta image, but the service's LIBVA_DRIVERS_PATH only searched /usr/lib/x86_64-linux-gnu/dri (empty) and /app/emby/extra/lib/dri (not populated on beta). libva then failed to load any driver and Emby reported 'Failed to initialize VA /dev/dri/renderD128. Error -1', falling back to software transcoding on any Intel GPU. Adding /app/emby/lib/dri to the search path lets libva find the bundled driver. Validated on an Intel iGPU: emby:beta went from 'Error -1' to detecting the Intel iHD driver with full codec enumeration. Harmless on images that ship the driver in extra/lib/dri (path simply ignored). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Description:
Adds
/app/emby/lib/dritoLIBVA_DRIVERS_PATHin the Emby service run script (root/etc/s6-overlay/s6-rc.d/svc-emby/run).On the beta image, Emby ships its bundled VA-API drivers (iHD, i965, radeonsi, etc.) under
/app/emby/lib/dri, but the service'sLIBVA_DRIVERS_PATHonly searched/usr/lib/x86_64-linux-gnu/dri(empty) and/app/emby/extra/lib/dri(not populated on beta). libva therefore couldn't find any driver, and Emby reported:…for both VAAPI and QuickSync, silently falling back to software (libx264) transcoding on any Intel GPU (Arc dGPU or iGPU). Adding
/app/emby/lib/drito the search path lets libva locate the bundled driver. It's appended after the existing entries, so it's harmless on images that ship the driver inextra/lib/dri(the path is simply ignored when empty).A changelog entry has been added to
readme-vars.yml.Benefits of this PR and context:
Restores out-of-the-box Intel hardware transcoding (VAAPI/QSV) on the beta image, which is currently broken for all Intel GPUs. Without this, users get software transcoding with no indication of why hardware acceleration fails. The stable (
latest) image is unaffected because it ships the driver inextra/lib/dri, which is already on the path — but beta moved the driver tolib/dri, exposing the gap.How Has This Been Tested?
Ran Emby's own detection command (
ffdetect vaencdec) inside thelscr.io/linuxserver/emby:betacontainer with the service's exact environment, against a real Intel/dev/dridevice, before and after the change:Failed to initialize VA /dev/dri/renderD128. Error -1, empty Driver, no codecs.Intel iHD driver for Intel(R) Gen Graphics - 25.3.4, full decode/encode codec enumeration (H264, HEVC, MPEG2, VC1, etc.).Test environment: Intel UHD Graphics iGPU,
/dev/dri/renderD128, image base Ubuntu 24.04 (noble), Emby 4.10.0.x.Source / References:
