Will try on one of my Pi 5 tomorrow.
Nice dangerouslaser, will be trying as well. Does this retain @popcornmix's awesome 3D work?
great work dangerouslaser - please pull in popcornmix amazing 3D efforts. If the Pi can get on par with all the amazing DV work that has been happening in NUC/mini pc world, that would be incredible.
Btw, does this work on a Pi4 too or does it require a Pi5?
The RPi4 has Vulkan support on the GPU, so just give it a shot. Older RPi versions will not work. There is a project for Vulkan emulation on RPi3 and lower:
ATM it's incomplete. Maybe it's worth using AI to complete the project, but the hardware might still be too weak.

It's untested but IMHO unlikely to work on RPi4 as its GPU has about 50% the grunt of an RPi5 which is already on the marginal end of support, and DV depends on GPU performance.
It runs pretty good on my Pi 5/4GB, .srt gets purple though, minor problem.

Installed on a Samsung 850 evo ssd, with a small silent fan the Pi sits at 35C when idle and playing 4k FEL7 it stays below 45C.
chewitt Is this portable to RK3288?
dangerouslaser, I can test 3D and share logs with any test builds.

No hope whatsoever. RK3288 is about a decade too old in terms of CPU/GPU performance.

Oops! I meant 3588 - Rock 5B+
3d build to test here
3D is working fine for me on a LG OLED65E6V 
(have a modified oppo 203 for reference)
Dolby Vision P7 FEL is working with all the test files except "FEL TEST DT DL P7 CMV4.0 4000nits V4.mp4"
Dolby Vision is working with MKV, but not with full BDMV titles for me - I only get HDR10
And there is still a minor problem with the gui colors being wrong when playing Dolby Vision.

I ran smoke tests on a Rock5B a coupe of weeks ago and it ran fine (some frame drops when the OSD is active) but I have other things to finish before I circle back and think about creating test images.
Nice work dangerouslaser, who woulda thunk just a couple months ago we'd have DV, and w/FEL, today on a RPi??!!
Haven't had a chance to spend a whole lot of time, but a few things of note using my RPi5:
One issue is the OSD with DV playback, and weird colors and artifacts:
