Replaces the Windows port with a Raspberry Pi / Linux implementation on Raspberry Pi OS "Trixie" (Debian 13, aarch64, Wayland/labwc). The Windows code is removed here but preserved on the Windows-Player branch. Entry point ----------- linux/run_linux.py replaces windows/run_win.py. src/main.py stays platform-neutral; all Pi-specific behaviour is injected from linux/. Five bugs that prevented the port (all measured on real hardware) ---------------------------------------------------------------- 1. Kivy's PyPI wheel bundles an SDL2 built WITHOUT the wayland driver, so no window could be created (Trixie has no X server). linux/fix_kivy_sdl2.sh symlinks the system SDL2 over the bundled filename. 2. SDL2 requires WAYLAND_DISPLAY to be *set* - the socket alone is not enough, unlike wlopm. This broke every systemd/cron/autostart launch. linux_display.ensure_session_environment() detects and exports it. 3. Kivy's Clock resolves callbacks via func.__name__; a patch assigned under a different name crashed the player ~20s after a successful start. 4. The inherited signal_screen_activity() shelled out to tvservice, xdotool and ydotool - none exist on Trixie - and mis-escaped 'wlopm --on \*', so the display blanked after 10 minutes. 5. The launchers ran src/main.py directly, bypassing every platform patch and resolving the data directory one level too high. Web links --------- - --ozone-platform-hint=auto does NOT fall back to Wayland on Chromium 152; it aborts. The platform is now chosen explicitly. - The keyring password prompt is suppressed via the ENVIRONMENT, not the flags: launch_env() strips DBUS_SESSION_BUS_ADDRESS for the child so Chromium cannot reach gnome-keyring-daemon. - Teardown kills the whole process group (needs start_new_session=True); previously it silently fell back to terminate() and orphaned children. Video normalisation ------------------- A 4K video cannot play on a Pi 4: ffpyplayer decodes in software, measured at 0.90x realtime (1080p is 3.03x). Oversized media is downscaled to 1920x1080 at sync time using the hardware h264_v4l2m2m encoder (~31s for an 18s clip), triggered by resolution only so already-playable files are untouched. src/media_state.py owns the shared on-disk contract: a .kiwy-converting marker makes the player skip the item while it is being rebuilt, then the converted file is played instead. If nothing is playable at all (a single-item playlist whose only video is converting), the player loops the intro video rather than leaving a blank screen. Also fixed ---------- - network_monitor: replaced netsh/ifconfig/dhclient with nmcli (Trixie uses NetworkManager; ifconfig and dhclient are not even installed). - Removed the Windows-only focus keeper/guardian from main.py. - main.py: duplicate SDL_AUDIODRIVER setdefault (a silent no-op); Settings "Test connection" now uses tempfile.gettempdir(). - config/app_config.json: credentials blanked so a fresh clone runs the first-run setup flow. Verification ------------ linux/test_media_state.py 18/18, test_linux_patches.py 21/21, test_linux_browser_flags.py 27/27. Verified live against a real DigiServer: image -> weblink -> image -> video with correct durations, zero leaked Chromium processes, and no throttling over a 10 minute monitored run.
