Myy, both Gstreamer and mpv in libELEC would work

Well, is there the package "alone" ? I guess I could try to find a librElec distro and put a mainline kernel in it, but that might just generate more issues than anything

My solution to not-having-VPU-accel is "learn to love reading instead". Am I doing it right? :^)

rk3288 is more powerful than t7200 or whatever and it has no problem in decoding video

if someone gets xvideo working, it should be done

ah, thanks, need to try --sws-scaler=fast-bilinear

^^ fastest I'm able to get with pure software although it ought to be possible to get much better perf with VOP overlays and such
18:00

x11 I knew already

I tried reporting that as a bug on the mpv issue tracker... they did not appreciate the help apparenly

right now I don't have sound either, so getting video output seems less interesting
18:18
<
Ke >
I mean on rk3399
18:18
<

there is probably some race in initializing the codecs and the sound card
18:23

I have sound working on kevin but it was a pain

I can send my configs in a bit
18:23

(although I'm on CrOS kernel so maybe that's related)
18:31

I had sound working on 4.18-rc3 or rc-2
18:31
<
Ke >
after that I have improved the config quite a bit, but sound stopped working
18:35
<

if I get smooth video with that --sws-scaler=fast-bilinear, perhaps getting sound beck would be worthwhile

huh, ok

gles with drm out would, but I only started working on GLES drivers for this thing like a week ago so..

for rk3399 I assumed you'd want to do scaling via VOP (which I guess is that?)
19:41
<

and that's exposed over DRM
19:41

alyssa--- >
mpv just doesn't implement hw overlay support on --vo drm
19:42

I tried to implement it a few weeks back but kept hitting walls and I watch so little video that I couldn't justify the time spent :p

well then there is rockchip's gstreamer plugin which does the drm overlay afaik
