1st, I don’t quite understand why it’s me to provide such “a link to authoritative evidence”. Contrariwise, it’s me posting here exactly to get somehow these “authoritative evidences”.
2nd, I don’t care about Direct X surfaces, viewports and Adobe Premiere Pro. I’m talking of 10-bit videos (like HEVC Main10), on Linux, with proprietary Nvidia’s Linux drivers.
3rd, I happen to have a Quadro too (Fermi 600), and it doesn’t output 10-bit either (at least, over DVI-HDMI and Displayport-HDMI adapters)
4th, Pascal is marketed as having “PureVideo feature set H” (plenty of authoritative links can be found in internets). But as far as I can see, current drivers lack both 10-bit HW decoding (at least, with VDPAU), and 10-bit output (regardless being it video, viewport, or something else).
It quite may be that I simply misunderstand something, or just don’t know how to get these things working – and I would like to get an answer on how I can fix this. Otherwise, I will be forced to conclude that Nvidia’s marketing tells us (let’s put it as follows:) not the whole truth.
5th, if you don’t know what to say on topic – don’t bother answering.
PS. Don’t know if this link is authoritative enough or not https://devtalk.nvidia.com/default/topic/771081/?comment=4464366
