VA-API AV1 Decode Lands In Mesa 21.3 Gallium3D

[Masush5]

What about encoding?

There is no current AMD hardware that supports AV1 encoding.

Hm, somehow I'd don't have even H264 acceleration on my 6700XT with Mesa 21.1.7... does any one have any suggestions why?

Yeah I was about to post this. It's fixed in 5.14.rc6 and I imagine it'll be backported to the next 5.13 bugfix release but I'm not certain. Either way you can use the patch submitted in the Gitlab report to create a patched kernel module if you can't wait, I did this and its been working great

Oh, wow, thanks. I've switched to the 6700XT exactly on a day fedora released 5.13 kernel, so I thought it's been broken. Appreciate the pointer.

i always find audio and video support is lacking in Linux compare it to windows

If only Windows did a good job. It is always a bad joke.

Linux GUIs is one thing that AMD gets very, very wrong. They are not on the scene and they are nowhere in sight.

If it was an AMD only issue I'd buy that but when pretty much everyone isn't on the scene then it's not a surprise.

Linux not having a singular backwards compatible GUI toolkit is not making things easier. I mean there are things like Qt (which are properly cross platform as a bonus) but then you will always have someone from the Linux side complaining (i.e. gnome people saying it doesn't adhere to their design guidelines).

It's a shitshow all around. Qt is cross platform but cross platform toolkits are a never ending joke. They never look well across most of the OS's they support. You build with Qt and GNOME users will complain. You build with Gtk+ and KDE users will complain. I don't blame either side.

And as parent pointed out: if you build with GTK, you also have to deal with the fact that your code will either break, or at a minimum look different, with every GTK release.
I have no idea if Qt is any better on THAT front - but even Firefox, which is using GTK, on a GTK desktop, has literally NEVER rendered scrollbars etc correctly for more than maybe a month or two at a time at best, just because of GTK's CONSTANT random breakages from one version to the next. sigh...

True. But every ones next gen cards will at least for 4:2:0 sub sampling.
