[Unit]
Description=mpv persistent player (DRM/HDMI output, JSON IPC)
# Wait until udev has settled so the DRM/HDMI devices (/dev/dri/*) exist
# before mpv tries to grab the display. Without this, a cold-boot race can
# leave mpv running but never rendering to HDMI (you see the console instead),
# even though the exact same command works when run by hand later.
