This morning on my distribution (Fedora 29) a lot of packages was upgraded.
After this upgrade, CPU load while playing 4K VP9 videos was decreased in t=
wo
times.
And most importantly, the GPU was stop heated like it was yesterday. (1-2 L=
ED
only glow during playing video) And disappeared dropped frames.
But:
1) Error message "Failed to open VDPAU backend libvdpau_nvidia.so: can=
not open
shared object file: No such file or directory" are still out. I am als=
o want to
say that I not touched settings and don't know why mpv want load
libvdpau_nvidia.so library. May be you can help in where I can check this
settings.
2) Problem was gone only in mpv and Firefox (I am not checking another
players), but Totem still working as yesterday (GPU overheating, on the vid=
eo
card all LED are glow + 200% CPU and more ...)
3) On Firefox and mpv I was note that happens new problem. This issue in
desyncing video and audio. The video is always late.
4) CPU loading during playing video was decreases in two times in some
applications as I said above, but I am curious about 100% CPU load it norma=
l or
too much? I read somewhere that somebody's said that CPU load must does not
exceed 30% on the mobile CPU with IGPU during playing 4K video. It's true?<=
