Render Demo Preview
render_demo_previewRender a quick 480p/25fps preview clip from a demo. Use this FIRST to verify you have the right moment before a full-quality render. The demo is cut to the given server-time range (plus padding) and rendered completely in the background via xvfb-run + wolfcamql + ffmpeg. start_time_ms / end_time_ms come directly from seek_demo or get_frame_state server_time_ms values. Blocks until render is done. Requires WOLFCAMQL_BIN, WOLFCAMQL_BASEPATH env vars and xvfb-run + ffmpeg to be installed.
