render_wallpaper.py drives headless Firefox frame by frame (four at a time, resuming where it stopped), then ffmpeg. Thirty seconds at 30 fps is exactly one plasma cycle, so frame 900 meets frame 0 and the loop has no seam. plasma-plugin/dev.emil.video is a minimal Plasma 6 video wallpaper: one file per screen, filling the screen, looping. H.264 is encoded Baseline because Qt here decodes through openh264, which rejects High profile and leaves a frozen frame; a new source also has to be played explicitly. The #shot hash learned info=0 to hide the on-screen hint for renders.
