Mpv: Please make GPU device for hardware accelerated decode selectable

[cwbsw]

Most people have two GPUs, a Intel integrated GPU, and a AMD/NVIDIA discrete GPU. The decoding capacity of them are different. For example, the latest AMD Polaris GPUs don't support VP9 codec, and GTX 970/980 don't support HEVC codec. If mpv could support integrated GPU decoding, users would have more choices, especially useful for those who have both latest Kabylake CPU and old discrete GPU.

For Intel IGP and old Nvidia GPU you might want to use vaapi-copy https://github.com/mpv-player/mpv/pull/3609
It works with Skylake and should work with Kaby too.

However, vaapi-copy is just Linux only. I think it should be possible to support Intel integrated GPU by d3d11va-copy on Windows 10.

Why support malware?

[Hrxn]

What malware?
Sure this is the right issue?

@fhlfibh Does vaapi-copy work for AMD GPU?

@fhlfibh Does vaapi-copy work for AMD GPU?

I never had an ATI/AMD card, so I don't know for sure.
Afaik, it should work, in theory (but may be somehow tricky to set up in practice).

You said most people have two GPUs. Where did you get this information? I doubt this is a fact.

[Hrxn]

I think it's meant like internal GPU (like Intel Core CPUs, etc.) plus dedicated GPU, connected via PCI(e).

Yes, but I, for one, have never seen any numbers about how spread are those setup. There still a lot of laptops with Intel only. And I think they’re still some Intel procs without GPU. Not sure about AMD world.
