Feature request: Enable Intel Quick Sync (QSV) Support

[slymattz]

Hi!

Context:
Both FFmpeg6 and HandBrake in Void Linux are already built with QSV support enabled (libvpl-devel in makedepends in the former and libva-devel libdrm-devel libvpl-devel in the latter (x86_64*).

However, without the vpl-gpu-rt runtime package, these in-built QSV features are non-functional, as the runtime is required for actual GPU-based video encoding and decoding.

QSV hardware encoding is significantly faster and more energy-efficient than CPU-based encoding.
It reduces encoding time dramatically while lowering system load.
The required packaging work is already complete and verified by @zlice and @slymattz (see PRs below)

Proposed Solution:
To enable working QSV functionality, it is sufficient to merge the following two pull requests:
#51133
#57328

No rebuilds are required.

Hardware Coverage:
This would enable QSV for:
Intel Tiger Lake and newer integrated GPUs
Intel Arc GPUs (Alchemist, Battlemage)
Potentially future Intel graphics generations supporting the oneVPL runtime

Don't open issues just to ask that we merge existing pull requests.

Sure thing. I just figured it had been almost one and a half years since PR51133 was opened and decided to bring attention to this pull request as it seemed to me it could have long been forgotten. Additionally, what motivated me to open this issue was the fact that there is the "enhancement" label in Issues so I thought it's the right place to post something like this. But fair enough, I'll keep what you said in mind for the future.
