🎬 Execute ffmpeg command [video]

Execute raw FFmpeg commands for advanced video/audio processing operations not covered by template functions. CRITICAL RULES: - Command MUST start with 'ffmpeg' (lowercase) - NO command chaining: prohibited patterns include &&, ||, `, $(), >, >>, <, 2>, eval, exec - NO dangerous commands: rm, wget, curl are blocked - NO system paths: /etc/, /bin/bash are forbidden - Width limit: 2048px maximum (2K resolution) - Bitrate limit: 200M maximum for video/audio - Duration limit: 1200 seconds (20 minutes) maximum with -t flag - Output format: STRONGLY prefer .mp4 format for compatibility WHEN TO USE: Use this tool when template functions (create_video_from_assets, trim_video, add_subtitles_to_video, etc.) cannot achieve the desired effect. Common advanced use cases: - Custom filter chains (complex filtergraphs, color grading, advanced transitions) - Precise codec control (specific encoders, bitrate modes, pixel formats) - Multi-stream operations (multiple audio tracks, video overlays with timing) - Format conversions requiring specific parameters EXAMPLES: 1. Apply color correction and resize: ffmpeg -i input.mp4 -vf eq=brightness=0.1:saturation=1.2,scale=1280:720 output.mp4 2. Extract audio and convert format: ffmpeg -i video.mp4 -vn -acodec libmp3lame -ab 192k audio.mp3 3. Create fade in/out effect: ffmpeg -i input.mp4 -vf fade=t=in:st=0:d=2,fade=t=out:st=8:d=2 output.mp4 4. To grab the last frame of a video, use this: ffmpeg -sseof -3 -i "https://res.cloudinary.com/..." -vsync 0 -update 1 output.png RETURNS: Cloudinary URL of the processed video/audio file (automatically uploaded after processing). ERROR HANDLING: - Validates command structure before execution - Returns detailed FFmpeg error messages on failure - Verifies output file exists and has content
