description
Convert bookmarked videos from YouTube, X (Twitter), and other sites into a podcast RSS feed hosted on Cloudflare R2. Use when the user says things like "add this to my podcast feed", "add this video to my podcast", "sync my podcast feed", "put this YouTube video in my podcast", or "subscribe to this playlist as a podcast". Manages a persistent episode list and hosts audio files + feed.xml on Cloudflare R2.

video-podcast

Turn any video URL into a podcast episode. Publishes a valid RSS feed to Cloudflare R2 that can be subscribed to in Apple Podcasts, Overcast, Pocket Casts, and any podcast app.

Supports YouTube, X (Twitter), and the ~1,000 other sites that yt-dlp supports.

First-time Setup

1. Install dependencies

# Python packages
pip3 install yt-dlp boto3

# ffmpeg (required for audio conversion)
brew install ffmpeg        # macOS
sudo apt install ffmpeg    # Linux

2. Create a Cloudflare R2 bucket

  1. Sign up at cloudflare.com (free tier is sufficient)
  2. Go to R2 Object Storage → Create bucket
  3. Name it anything — e.g. podcast-feed
  4. Enable Public access on the bucket (R2 → bucket → Settings → Public Access → Enable)
  5. Note the r2.dev public URL shown (e.g. https://pub-abc123.r2.dev)

3. Create an R2 API token

  1. R2 → Manage R2 API Tokens → Create token
  2. Set permissions: Object Read & Write on your bucket
  3. Note the Access Key ID and Secret Access Key
  4. Note your Account ID from the dashboard top-right

4. Configure the skill

Run the interactive setup:

python3 /path/to/skills/video-podcast/scripts/video_podcast.py setup

Or add these to ~/.openclaw/.env manually:

VIDPOD_R2_ACCESS_KEY=your_access_key_id
VIDPOD_R2_SECRET=your_secret_access_key
VIDPOD_R2_ENDPOINT=https://<account_id>.r2.cloudflarestorage.com
VIDPOD_R2_BUCKET=podcast-feed
VIDPOD_PUBLIC_BASE=https://pub-<hash>.r2.dev

# Optional
VIDPOD_FEED_TITLE=My Video Podcast
VIDPOD_FEED_AUTHOR=Your Name

5. Add a cover image (optional but recommended)

Podcast apps display a 1400×1400px JPEG as artwork. Upload one to your bucket:

# Using AWS CLI (if installed)
aws s3 cp cover.jpg s3://podcast-feed/cover.jpg \
  --endpoint-url https://<account_id>.r2.cloudflarestorage.com \
  --content-type image/jpeg

# Or via the Cloudflare R2 dashboard — drag and drop cover.jpg into the bucket

The image must be named cover.jpg in the root of your bucket.

Usage

Add a single video

python3 video_podcast.py add "https://www.youtube.com/watch?v=..."
python3 video_podcast.py add "https://x.com/user/status/123456789"
python3 video_podcast.py add "https://vimeo.com/..."

Sync a YouTube playlist

Add all videos from a playlist that aren't already in the feed:

python3 video_podcast.py sync-youtube PLxxxxxxxxxxxxxxxx

The playlist ID is the part after list= in the YouTube URL.

List episodes

python3 video_podcast.py list

Get the RSS feed URL

python3 video_podcast.py feed

Remove an episode

python3 video_podcast.py remove "https://www.youtube.com/watch?v=..."

How It Works

  1. yt-dlp fetches the best available audio stream from the source URL — no browser automation, no screen capture.
  2. ffmpeg converts the audio to MP3 (VBR ~130kbps).
  3. The MP3 is uploaded to your Cloudflare R2 bucket with a 7-day public cache header.
  4. feed.xml is rebuilt and uploaded with no-cache headers so podcast apps always see the latest version.
  5. Your podcast app polls the feed URL periodically and downloads new episodes automatically.

Storage & State

Location Purpose
~/.openclaw/video-podcast-state.json Episode list + processed URL GUIDs (deduplication)
R2 <guid>.mp3 Audio files (public, 7-day cache)
R2 feed.xml Podcast RSS feed (public, no-cache)
R2 cover.jpg Podcast artwork (optional)

Supported Sources

Any URL that yt-dlp supports, including:

Troubleshooting

ffmpeg not found

brew install ffmpeg   # macOS
sudo apt install ffmpeg  # Linux

SSL errors with R2 Make sure you're using Python 3.10+ with OpenSSL 3.x. On macOS the system Python (/usr/bin/python3) uses LibreSSL which may not work. Install Python via Homebrew:

brew install python@3.13

Age-restricted YouTube videos yt-dlp needs your browser cookies:

yt-dlp --cookies-from-browser chrome "https://youtube.com/watch?v=..."

Then run add again — yt-dlp caches the cookies.

X/Twitter videos fail Public tweets work without auth. Private accounts require cookies:

yt-dlp --cookies-from-browser chrome "https://x.com/user/status/..."

Episode not appearing in podcast app Most podcast apps cache the feed for 1–24 hours. Force a refresh in the app, or check the feed directly: python3 video_podcast.py feed

OpenClaw Agent Usage

When used via the OpenClaw agent, trigger phrases include:

  • "Add this to my podcast feed: [URL]"
  • "Add this video to my podcast"
  • "Sync my podcast from playlist [ID]"
  • "What's in my podcast feed?"
  • "Remove [URL] from my podcast"

The agent will run the appropriate subcommand and report back the result.
