2nd play failure (update)

[dream7180]

Archlinux as a HTPC and NAS server (no desktop): nodejs-18.7, npm-8.16, mpv-0.34.1, ffmpeg-5.0.1 (all official build) mpv-remote-node and app are up-to-date. I run mpv and mpv-remote-node as an system service (mpv.service as below):

[Unit] Description=MPV Media Player After=network-online.target

[Service] User=root Group=root Type=simple ExecStart=/usr/bin/mpv --idle ExecStartPost=/usr/bin/node /root/.config/mpv/scripts/mpvremote/remoteServer.js --expose-gc Environment=NODE_ENV=production Restart=on-failure RestartSec=6 RemainAfterExit=yes

[Install] WantedBy=multi-user.target

mpv-remote APP connection is OK, and play a video by the APP is OK. After the first play is stopped, I choose another (or just the same) video to play, it will fail. The APP connection is still OK, but unable to play unless I restart the mpv.service, problem repeated. It happened since the last issue I raised. It has noting to do with the uselocaldb. Now the service log changes, please take a look, I can not confirm whether mpv or mpv-remote or ffmpeg cause this bug.

Interesting MPV-remote should not affect your decoding settings. The remote server mainpulates only the HTTP Header fields when opening stream from other apps for example Aniyomi.

These lines look suspicious for me. It seems by some reason MPV cannot get Video device and XDG_RUNTIME_DIR has been not set. Maybe try running MPV without the daemon.

BTW: I did a pull request on node-mpv, no response yet (it's been a month). For next release probably gonna replace node-mpv with my fork. Based on recent activity of project, seems it's not maintained anymore. I'll try to maintain it.

XDG_RUNTIME_DIR not set will not cause failure. problem is that 2nd playing can not load GPU decoding anymore. I think run mpv in idle mode is not an issue, and have to do this to keep connection for mpv-remote app. [vo/gpu] Failed to commit ModeSetting atomic request (-13) [vo/gpu/opengl] Failed to set CRTC for connector 95: Permission denied

If I disable GPU decoding (vo=drm in mpv.conf), then everything will be OK. But this is not what I want for it will cause high CPU occupation.
