I compiled Gentoo on Raspberry Pi 5 with 8GB RAM, and my own custom kernel. But there is no hardware acceleration when playing videos, either in browser or using mpv. Mpv say vo is gpu, but playback is worse than on Raspberry Pi 4. Same result with official kernel.
Mesa is at ver. 23.3.3 with v3d and vc4 videocards enabled, kernel is 6.6.12, DE is xfce 4.19, firefox is v121, also vivaldi was used, ffmpeg has support for v4l2 mml. Tried also hyprland (full wayland), but same result. Of course, glxinfo report: direct rendering: Yes.
Video playback is very good only at HD resolution, CPU usage is relatively high, but no framedrop, is acceptable at 2K and completely broken at 4K resolution.
Why I am posting here and not in Gentoo section: I something that Bookworm on Pi have and is not upstreamed in mesa ? Is a setting in config.txt ?
Display resolution is not autodected, I had to put dtoverlay=vc4-kms-v3d-pi5 in config.txt to gain 4K resolution (both framebuffer and graphical interface).
Full config.txtAny hint ?
Thank you!
