Hi,
Is there any hardware accelerated video decoding in OpenBSD today?
E.g. in X on AMDGPU and Intel & ARM64 built-in graphics.
My best understanding is that the X graphics rendering is indeed
accelerated on those, but video decoding is not.
HW accelerated video decoding would be very useful as high-resolution
full-screen playback not really works now because there's too much
lag (or maybe I had unsupported hardware, if so glad to be corrected). It
would contribute to a sense of smoothness in X/web browsing.
well...I have some pretty old hw that I don't seem to have any issue
watching full screen 1920x1200 video from YouTube. Or 1920x1080 on my
other monitor. On both Firefox and Chrome. Zero efforts to optimize
performance, just tweaking login.conf to respect the expectations of
modern browsers so they don't get slapped out of RAM for excess memory
consumption.

[pretty sure both those video cards were always lame]
Now, I'm not very picky, but I don't see obvious lag. Kinda sucks,
I was much more productive before youtube and other video sources
became fully functional in OpenBSD. :)
