I'm very happy about #gnomeshell / #gnome47 shipping HW encoding for its internal screen recorder. With the upcoming #gstreamer 1.24.6 release all currently known bugs are fixed, even though I kinda expect more to come on some multi-GPU setups.
It's about time that we use hw-enc in more places by default and the screen recorder is IMO in a pretty good spot to role things out: on one hand it's used by many people, ensuring we get bug reports, while OTOH its functionality is not crucial.

If things are broken for some users they have lots of alternatives to switch to.

In #gnome47 we'll limit things to H264 on (semi-recent) Intel and AMD (those using VA-API). In the future we'll hopefully be able to extend things to AV1, maybe VP9, and more platforms. Depending on how things develop that'll be V4L2 or Vulkan.

@rmader if going for semi recent hardware then why not go for h265 or would that be too incompatible

Robert Mader

@zyx Compatibility. H265 doesn't work on the web, HW-decoding is supported on less devices etc. VP9 and AV1 are options I'm looking forward to - H265 is not worth it, IMO.

@rmader @nekohayo this is the thing Aral was complaining about, right? funny how it happened without any help/input from him whatsoever

Brage Fuglseth

@rmader On a positive note, though, I'm stoked for this! Modern hardware enablement is great.

@bragefuglseth @nekohayo Err, this is about the screen recorder, not screen reader ;)
But fortunately the later is getting resolved as well, see floss.social/@sonny/1127733995

@rmader Oh, you don’t know about his screen recorder rant? It’s separate from the screen reader ragebait. See this discussion (start from the top) mastodon.social/@nekohayo/1126

@rmader I’d argue that this is a major part of why people were fed up with him when he started smearing the Fedora community right afterwards.

Robert Mader

@bragefuglseth Oh, wasn't aware about that, thanks for letting me know!
And yeah, hw encoding allows us to produce videos with much better quality - but IIRC for professional videos you'd still want to use OBS with optimized setting. Something something 4:2:0 subsampling is not nice for RGB content and something something sw encoders produce better quality than hw ones or so.
