Automatic hardware encoding settings by architecture

[tknx]

It would be nice if I could just have Jellyfin see that I am using an Intel Rocket Lake and prepopulate a good set of default hardware encoding settings instead of making me go back and forth with the Wikipedia article and try to map that to the settings.

It would require a bit of database work to map what is supported by each GPU, but would make setup a lot easier and avoid incompatibilities.

In addition, the mapping could be more exact, in my example, Rocket Lake for HEVC only supports encoding at 4:2:0 only and does not support AVC High 10, but there doesnt seem to be a way to get that granular in the settings.

The problem is that even within a generation of CPUs/GPUs there are inconsistencies. AMD and Nvidia are the bigger offenders. Intel is pretty consistent, but there are still exceptions. So having a static mapping would require a lot of work and validation.

Even using vainfo to attempt to get a GPUs codec support is not a guaranteed way the get the full picture.

Since we are not a for-profit business, we don't have dozens of test benches with various hardware combinations to validate this kind of capability.

Having said that, there are efforts to figure out an acceptably reliable way of doing this. No ETA.

Yeah, I think there are a couple of ways to do it.

Maybe the most dev heavy way would be to run suites on each processor to test encoding and decoding and then catalog the success and failures for that specific architecture.

The other might be something like the other post where you were helping me out and just say, okay for Rocket Lake these are the defaults and if people want to mess with them, fine. And then add in architectures as they are validated.

But I recognize it is a pain in the ass no matter what, especially if AMD and others aren't providing the exact specs easily. Would the ffmpeg group or someone already have this? I feel like someone would...
