Reviving this old thread now that rkvdec2 'stuff' emerged.
I have (actually) done quite some tests with this (and "media: rkvdec: Add
HEVC backend" patch set) and they have been part of my kernel builds ever
since.
I _think_, but don't know, that is relevant for Andy's question:

I have the same question and I think you'd need this and the HEVC patch set
and then also patch FFmpeg and then it should enable HW acceleration.
So my question boils down to: with the rkvdec2 patch set, should V4L2-requests
now also work with rkvdec, so not just Hantro anymore?
BTW: the libdrm commits have been merged upstream quite some time ago, so if
you have a recent version of that, you don't need to patch that.
If you use FFmpeg 7.0, then Jonas has a branch for that too (haven't tried it
yet though).
FWIW: my test results were a bit mixed. I didn't post them before as I don't
fully/really understand this 'video stuff', and I didn't want you all to suffer
from what was likely a PEBKAC issue.
On my PineTab2 (rk3566) I had some h.264 videos HW accelerated, but not all.
My guess is that it's related to the resolution. 1920x1080 worked, while it
didn't work with a 1280x640 video. The video still played, just not HW
accelerated. IOW: improvements in some and otherwise it was just rendered by
the CPU (I think), just like before.
On my Rock64 I got a pink tint with all videos, like described here:
https://github.com/mpv-player/mpv/issues/12968
IIUC, that's actually a problem in the lima driver?
