I occasionally write long posts but you should assume I'm talking out of my ass until proved otherwise. I do like writing shit sometimes.

50/50 chance of suit pictures end up here or on the Art Directory account. Good luck.

Be 18+ or be gone you kids act fuckin' weird.

I tag all of my posts complaining about stuff #complaining, feel free to muffle that if you'd like a more positive cohost experience.

Hey smarties can you fact check this for me?

I wanted to know what the oldest CPUs that would have sufficient hardware decode for 4k 60 video, just in case, and as far as I can tell it appears to be Intel CPUs with 600 series graphics, which would be "Kaby Lake" and later (7000 series), and AMD APUs with Vega branded graphics, which is basically anything Ryzen based, including the "Bristol Ridge" Athlon branded CPUs such as the 200GE and 3000G.

This is based mostly on checking the inconveniently named bluesky software website, who apparently makes a program that checks for Direct X video acceleration. They also just, have tables on the website. Here's the one for Intel, and here for AMD. See also the wikipedia pages for AMD's UVD and Intel's QSV.

The only snag here is that these are just hardware features and Windows support, obviously I care about working decode on Linux. Given neither of these companies are Nvidia I would expect hardware decoding to just work out of the box with the correct video player, such as mpv, but figured I'd ask before juggling systems around to actually find out. I'm sure someone has done this before.

I'm including VP9 in this because, let's be real, youtube sourced video is basically a standard now. If I can't downscale Gravis' face to 1080p instead of just telling mpv to download the best 1080p quality instead, what's the point?

imo a cpu with QSV is your best bet, intel has a lot of contributions directly to the linux kernel so as long as you are on kernel >6 you should have full support

Plum @plumpan4/14/2024, 5:51 AM

I imagine/would hope Vega works too, it's more a toss up of which one I can find for cheaper at that point. You'd think Kaby Lake desktops would be scrap money now but those 2400GEs are pretty cheap too. I've got a 2400GE and 3000G on hand that I can test with later.

The end goal of this is potentially a "if you want to make a media center PC nowadays, here's what to look for" guide so if both work that's even better.

in other news i just picked up the CM3588 nas kit which is based on the RK3588 and it’s hw video accel has been solid so far. $170 shipped and it has 4 nvme slots and the VPU can do 8k60 (untested but 4k60 worked) as well as 4k60 capture?? it’s a nice bit of kit

I'm done touching ARM kit, they're too damn fussy for me. They're real cool when you get them running, and I'm all about the power efficiency on them... but ugh.

Thankfully used office PCs are available <$100 shipped all day here, and you can usually get it fully working with all the parts required for at or under $100 too. That's my hammer now.

What OS do you plan on running on that? I'm assuming rolling your own setup for NAS duty instead of TrueNAS or whatever?

nys @nys4/14/2024, 7:54 AM

i’m actually thinking about using it as video capture/recording so probably rolling my own based off a friendly distro with a lightweight de. given that a like elgato pro mk2 or avermedia top capture cards are like $200 i think it would be really cool to offer a super budget option as a kind of experiment.

nys @nys4/14/2024, 5:51 AM

here’s the arch wiki on the relevant options (imo they are broadly what you’ll have access to on other distros): https://wiki.archlinux.org/title/Hardware_video_acceleration

Plum @plumpan4/14/2024, 5:54 AM

It was at this moment that I realized my desktop doesn't have hardware decode for VP9. This explains some things!

Nevermind the fact that I've been reading pages for the past hour telling me my GPU doesn't do it.

https://wiki.archlinux.org/title/Hardware_video_acceleration#Comparison_tables ahhhh exactly what I wanted. Thank you!
