Radeon VCN Video Decode Support Lands In Mesa

That's not a real solution. Its only limited to Linux and it has its own Problems. The easiest solution would be OpenMax in the Windows Driver with De- and Encoding capability.

Openmax is supposed to be disgusting. Like, similar to fully supporting matroska.
vaapi may be slice based, but it appears to be well defined.

vaapi may be slice based, but it appears to be well defined.

And its totally uninteresting since it can't use the encoding features (and not even decoding is fully supported) and its limited to Linux.

Openmax is supposed to be disgusting.

Why? Its supported by ffmpeg.

Like, similar to fully supporting matroska.

??? The Container is also uninteresting in this case.

Because you ignore the Encoding Part. If you decode only on the hardware and encode on the cpu you benefits are to small.

No I don't. Obviously, I don't, otherwise I wouldn't have written it

For BD Support you need it.

Vast majority of Blu Rays is enoded in h.264. Also, you "can't" really play BDs on Linux anyway due to DRM. And if you can, software decoding a 1920x1080 stream with <24 fps is no problem at all. I just don't see the reason putting fixed function hardware for that it but leaving VP9 out.

VC-1 = WMV 9 = Lots of HD videos from pre-2009, before MPEG-4 became the standard for web video downloads.

Older Blu-Rays, which are pretty much the only ones you actually can play on Linux, were encoded with MPEG2 or VC-1.

Therefore, it's useful to a lot of people.

VP9 is not relevant at this point because it has no real-world use other than Google's own infrastructure.

Yeah, just like the internet is irrelevant
Something around 2/3 of the worldwide traffic is video, mostly YouTube. Netflix is also using vp9, btw. 2013(!) Netflix+YouTube were responsible for over 50% of the traffic. I didn't even know Netflix back then.

That's probably because the industry does not and will never care for open-source codecs.

Actually, the industry does not care whether the codec is open source or not.

But it would be much different if that codec were standardized by MPEG, ITU, or some other recognized standards body. Google has apparently recognized this, and submitted VP9 to the AV-1 workgroup, as did Mozilla (Daala) and Cisco (Thor) to create a vendor-independent open standard. That could see broad industry adoption once it is finalized.

There were times when most Internet traffic was bittorrent, or when the most searched term on Altavista was "sex".
Youtube or Netflix can switch out VP9 for any other codec on a whim, while for a hardware manufacturer this requires years from silicon design to final product.

Which is exactly why they can't and don't.

Go do your software decoding on a raspberry pi (v1). The computing world is bigger than stupidphones and PCs. not to mention better energy efficiency of fixed pipeline decoding.

That would be one big whim... I honestly do not believe they do live transcoding.

What does the porn industry use? That is the important question

Now the important question :
So what is VCN and what does it support?
decode : MPEG-2/h264/vc-1/h265
encode : h264/h265 (all profiles + 10bit?)

That's probably because the industry does not and will never care for open-source codecs. Just look at audio codecs.

that's bullshit. just look at aomedia member list

encoding is much more rare than decoding, i.e. who cares
