Add PHP Video Converter Suite with live stream pipelines and nuclear control panel UI
Full-featured video conversion platform with: - FFmpeg-based pipeline system with composable stages (transcode, scale, filter, audio, bitrate, framerate, trim, deinterlace, denoise, stabilize) - Live stream management with real-time format switching (RTMP/RTSP/HTTP) - Industrial/nuclear power plant control room themed UI with gauges, switches, LED indicators - Format switchboard for instant conversion between 16+ video/audio formats - Pipeline designer with visual flow editor and drag-and-drop stage composition - Job queue with priority scheduling and batch conversion - WebSocket server for real-time progress broadcasting - REST API for all operations (upload, convert, streams, pipelines, queue) - System monitoring (CPU, memory, disk) with animated gauge displays - Docker Compose setup with web, websocket, and worker services https://claude.ai/code/session_01WxmHGnVFXGm2bwbFREHkHb
