robertoj Posted 3 hours ago Posted 3 hours ago (edited) 1 hour ago, jock said: I compiled mpv 0.40.0 on Debian Trixie with the patches for v4l2request, but the outcome is messy at best. There is a new hwdec v4l2request, but also two new gpu-hwdec-interop v4l2request and v4l2request-overlay. It works with acceleration when launched from a terminal, but in wayland/weston v4l2request refuses to work. I don't know what happened, but it looks like a big regression from 0.39. Better use the old mpv version IMHO. I thought that v4l2request was exclusively in this github project and branch: https://github.com/philipl/mpv/tree/v4l2request Which github project and branch/release are you trying? I successfully compiled and installed the mpv from https://github.com/philipl/mpv/tree/v4l2request I made the /etc/mpv.conf as per the original post Result: 50% cpu in 4 cores, about half dropped frames: Spoiler roberto@orangepizero3:~/mpv-philippl-v4l2request/mpv$ DISPLAY=:0.0 mpv -v ~/donde\ venderan\ buen\ trago\ 720p.mp4 [cplayer] Command line options: '-v' '/home/roberto/donde venderan buen trago 720p.mp4' [cplayer] mpv v0.1.0-18356-g17a8ef7e8 Copyright © 2000-2025 mpv/MPlayer/mplayer2 projects [cplayer] built on Oct 5 2025 18:48:33 [cplayer] libplacebo version: v7.349.0 [cplayer] FFmpeg version: 7.1.1-1 [cplayer] FFmpeg library versions: [cplayer] libavcodec 61.19.101 [cplayer] libavdevice 61.3.100 [cplayer] libavfilter 10.4.100 [cplayer] libavformat 61.7.100 [cplayer] libavutil 59.39.100 [cplayer] libswresample 5.3.100 [cplayer] libswscale 8.3.100 [cplayer] Configuration: [cplayer] List of enabled features: alsa build-date caca cdda cplugins debug dmabuf-interop-gl dmabuf-wayland drm dvbin dvdnav egl egl-drm egl-wayland egl-x11 ffmpeg gbm gl glibc-thread-name glob glob-posix gpl iconv jack javascript jpeg lcms2 libarchive libass libavdevice libbluray libdl libplacebo linux-fstatfs lua52 memfd-create memrchr pipewire posix posix-shm ppoll pthread-condattr-setclock pulse rubberband rubberband-3 sixel sndio sndio-1-9 uchardet v4l2request vaapi vaapi-drm vaapi-wayland vaapi-x11 vdpau vector vk-khr-display vt.h vulkan wayland wayland-protocols-1-32 wayland-protocols-1-38 wayland-protocols-1-39 wayland-protocols-1-41 wayland-protocols-1-44 x11 xv zlib [cplayer] Setting option 'v' = '' (flags = 😎 [clipboard] Initialized vo clipboard backend.
