Intel Gen12/Xe Graphics Have AV1 Accelerated Decode - Linux Support Lands

[discordian]

Please learn to fucking read, I didn't say that. I said that it's mostly useful for media that is BIG, while compressing 1080p won't see the same massive compression space savings.

From my own experience HEVC does save alot on bad quality footage (without me noticing a difference, even with some filters showing the difference), less on high quality.
Or put differently, HEVC will still look good at lower bitrates than H264.
At high bitrates the differences quickly vanish.

Only if you are into downloading and storing 10-15GB per movie. The 2-4GB version is always in 264 (and usually also 720p or something). For A LOT of movies it's really not worth the space and bandwith/time, which is why the h264 still exists for all movies.

Not at all, do I need to get the bartender post links from my account ?

Oh I have no doubt it will be H266, I'm just saying it will be mostly there for show while the media that actually needs it is rare.

I think you have the usecase reversed, the newer formats will allow lower bitrates for "ok" quality (the likes streaming services use).

Ah yes and of course the CCTV camera manufacturers will use it to claim massive size reduction or something like they did for h265 (where in practice it is an inflated number and I could do the same by tweaking a bit h264 encode settings in a system that isn't embedded bullshit and lets me do that).

How long ago did you test this?
The last two years H265 easily went past H264 in all regards, both from what my Huawei Phone can do (reencoded alot of my older stuff last year, tried both x264 and x265), and what tests report: https://www.compression.ru/video/cod...son/hevc_2019/

You mean like Netflix? Yeah no one sends movies over the internet.

(Pirates aswell, HEVC is pretty much standard now

Id guess that cameras will pick one format, and TVs will follow. Id further guess that this will be H266 or EVC, as HW for realtime encoding is a design criteria for those.

as said above, it's inconvenient and the main use is huge media that is at odds with internet speeds. Yes they will pay lip service to it for a lucky few, but it's going to be 265 all over again.

(Pirates aswell, HEVC is pretty much standard now - I heard from a friend's bartender I barely know)

With the added issue that 266 is unlikely to be adopted in a new and unlikely optical disk standard for movies or something.

I mean I hope EVC succeeds, but why?

It's not. All content providers will be all over lowered bit rates

unless it is very useful for 1080p (and I doubt it), i really doubt it will see much use. I mean yeah they will add it to their infrastructure in some capacity but who is watching a 8k stream anyway, as even with better compression it's far too large for most internet infrastructure.

[discordian]

It seems to me that AV1 repeats the mistakes of VP8/VP9, by not proving their standard with multiple software/hardware implementations before finalizing it (with conformance tests suites). See the sorry state of HW acceleration in Linux, with AVC/HEVC you can be pretty sure HW will adhere to standards and not randomly crash.

H266 is DOA

They can't add support for something that did not exist when the hardware was designed.

I only meant: unreleased hardware lacks support, it will be a while till we see the next generation.

[starshipeleven]

So... No H266 for at least a couple more years. Not surprised at all.

is this aisc based or gpu based decoder?

both are entirely different thing
asic offers, decoding with powersaving
gup offers decoding at thecost powersaving(though better than cpu)
