HDR HEVC transcodes were failing with "Failed to get number of OpenCL
platforms: -1001" (CL_PLATFORM_NOT_FOUND_KHR). The tonemap_opencl
filter jellyfin-ffmpeg uses for HDR-to-SDR tone-mapping needs an OpenCL
ICD, which intel-media-driver/vpl-gpu-rt don't provide on their own.

HEVC HDR transcodes were failing with "Error creating a MFX session: -9"
because intel-media-driver only provides VAAPI, not the separate
oneVPL/MFX runtime QSV needs to create a hardware session.

Jupiter's Intel iGPU is configured at the OS level but Jellyfin has no
access to it, so transcodes run on CPU only and stutter.
