Again if you test with downloaded (local) videos, vdpau doesn't work for webm, but works for .mp4 and .mkv. Also, if you use vdpau, mpv is a better option than vlc.
Yeah. I like MPV quite a bit more, but VLC has the whole kitchen sink baked in... no additional drivers required. My current work-around for YouTube is to copy the link directly into VLC, and just watch it that way. This way the video runs through VDPAU and uses the HW Video Decoder. Barely any CPU time is used. However, this limits my YouTube viewing to 720p, even if the Video is in 1080p (or higher.) YouTube separates their video and audio when it's over 1080p. There used to be a way to grab both streams, but it's no longer available... Oh well, I guess. Here today, gone tomorrow.
What I am directly attempting to do, is get Stadia working with HW Acceleration. With Software, the decode time isn't as fast as it could be with H.264 video. I can run VP9 as well, but it uses more of the CPU, and the decode time is the same. IMHO, this is one of the best ways to game (for me), due to it being fairly hardware independent, and available on Linux. But, is slightly disappointing at this point, because of the lack of HW Video Decoding.
With (True) HW Acceleration, the decode time drops sufficiently, and allows for consistent 1080p streaming. Without it, or even with "HW Assisted Acceleration" the resolution stays at the 720p area for the proper decode time (speed.)
This was tested in Windows 10 on a friends computer, and it works great. H.264 is Hardware Accelerated, and it streams at full 1080p (4K if you have it). The decode time is significantly lower, and it never (seems to) drop from 1080p down to 720p.
So, I am a little bit bummed out that we now have services like Stadia (Luna / GeForce Now / and soon XBox Game Pass) which would eliminate the need for specific hardware and operating systems... but then only quasi-support.
Holy Cripes on Toast!
