Video playback hiccups with Fedora 35 on RockPro64

[whitecat23]

... just to see what the machine's capabilities are. If 'dual-booting' between µSD and eMMC storage is what it takes to get the job done, well, I'm okay with it for now. I'll continue searching for a Fedora-specific solution, and post back if I find one.

I can't offer anything for Fedora and doubt I have any 4k files. But for me mpv is great, runs about 25% CPU of one of the little cores playing one of my videos full-screen. (So in my case appears bags of horsepower left and I don't ever have stuttering.)

Code:

$ lsb_release -a
LSB Version:    1.4
Distributor ID:    Arch
Description:    Arch Linux
Release:    rolling
Codename:    n/a
chris@RPro64:~$ uname -a
Linux RPro64 5.16.3-1-MANJARO-ARM #1 SMP PREEMPT Fri Jan 28 00:39:47 CET 2022 aarch64 GNU/Linux

Thanks, but unfortunately it seems MPV has serious issues with Wayland and Gnome. I tried playing a couple of short videos in 4k, and they were unwatchable. I came across a suggestion that's supposed to get things going with nVidia hardware, and thought to myself, would it also work with Mali? But it didn't make a difference on my kit. After reading on it a bit, I'm beginning to think that Gnome might just be the problem. Next week I'll have some time to check out LibreElec and look into other options. I'm almost now certain this isn't a RockPro64 problem, rather a software one.
