AFAIK, Vega was designed long after Kaby Lake was locked down and since Intel doesn't do anything radical with their architectures - they just shrink things for the most part - and has more resources than AMD or Nvidia, it's easier for Intel to implement new things into their decoders.

Ask Sir Bridgeman. I think it was probably the fact that AMD was in a bit of a crisis and had to focus on the important things. Technically speaking, AMD sold all the video decoder stuff to Broadcom back in 2006, so they lost the personnel and R&D that ATI had built up for years. Had they kept it, I think they would have had a much better IP portfolio and resources to handle today's multi-media landscape. Back then, ATI cards were very much considered the Go-To choice for XP media center PCs and they had the whole CableCard thing going for them too, at least until AMD cut that shit off.

vaapi-egl interop is a better bet than omx on Desktop Linux, but you'll have to wait for libva-2.0. It's not AMD's fault that there's no vaapi-egl yet, libva is designed too much around how Intel hardware works, but there is a proposal for a more flexible interface in libva-2.0 which will make egl interop on AMD possible.

I see. But how is this hybrid decoder supposed to be used then? When I check vainfo / vdpauinfo for Polaris (RX 480), there is no trace of VP9, while it supposedly should also have that hybrid decoding support.

Edit: But this doesn’t mean it works on Wayland, my fault.Last edited by holunder; 16 August 2017, 07:36 AM.

A bit of messing around I guess to replicate the "shortcut" convinience of all the options --vo=opengl-hq transparently enabled , but --target-trc=srgb does work as before with that (which is mainly what I would only have missed anyway).
Edit: on wayland I wasn't realy concerned about that - last time I tried weston any fullscreen video got trashed by some tiling issue, the patch for which got "discussed" to death. Maybe things are different now, it was a while ago.Last edited by legume; 16 August 2017, 07:55 AM.

BTW: Amongst the many interesting commit messages in your amd-staging-drm-next tree (which I currently run to enjoy HDMI 2 support) I spotted one regarding HDR10 signaling: https://cgit.freedesktop.org/~agd5f/...28243e6f41b64a
Is it way too early to ask for this, or is there already preliminary support for emitting an HDR signal via HDMI? If so, how would one configure the X11 server to make use of it?
