I just recently encountered some trouble with this domain the other day. I was trying to port a video project from an intel system that was using their QuickSync solution for hardware h.264 decode to a Raspberry Pi 4 using the V4L2 hardware decode API (the Intel system is before the breaking IPU6 change in Alder Lake discussed in the article). In both cases, it's to hardware accelerate FFMpeg decoding on Linux. This was trivial to accomplish on the system with Intel QuickSync, I still don't have V4L2 working properly on the Pi 4 and have had to wade through several complex issues.

Yeah it's complicated to get V4L2 working on Linux and requires recompiling a few things from my experience - we eventually got hardware acceleration on ffmpeg on Ubuntu + RPi working but it was a lot of trial and error, and I really didn't document it too well... can't imagine this won't come back to bite me...
