Video decoding on NVIDIA
Please buy some real Linux hardware.
This doesn't really help at all. Is it supposed to be funny, or is it
just cynical resignation?
After trying to configure HW acceleration on 9xx series GPU, I'll just take
that as a serious response.
Consider following points:
* VDPAU is not compatible with Wayland, our main desktop scenario.
* Video decoding in Firefox on X11 is limited to X11/EGL, which does not work
with the Nvidia proprietary driver (but at least there's a hope for that
scenario).
* There's no NVDEC vaapi backend, and I see opinions that it would be hard to
fit NVDEC into vaapi model.
* Nouveau support ends at VP5 (7xx series).
The wording might be different, but _at the moment_ any recent Nvidia hardware
cannot be used for HW video acceleration in Firefox.
