LBRY Downloader

A Python tool that incrementally syncs downloadable file claims from configured LBRY/Odysee channels into a structured local archive.

Features

• Incremental Sync: Only downloads new claims and updated versions
• Version Preservation: Keeps old versions instead of overwriting them
• Robust Identity: Uses stable LBRY claim IDs, not display names or titles
• Atomic State: Database writes are atomic to prevent corruption
• Daemon-Based: Talks directly to local lbrynet daemon via JSON-RPC
• Flexible Input: Accepts Odysee URLs, LBRY URIs, or claim IDs
• Audit Trail: Maintains run history in JSONL format
• Dry-Run Mode: Test what would happen without downloading

Installation

One-Line Install (Easiest)

Install with a single command:

curl -fsSL https://raw.githubusercontent.com/PR0M3TH3AN/LBRY-Downloader/main/remote-install.sh -o install-lbry.sh && bash install-lbry.sh

Requirements: Git and Python 3.8+ must be installed.

Easy Install (Recommended)

Run the interactive setup script that handles everything:

# Clone the repository
git clone https://github.com/PR0M3TH3AN/LBRY-Downloader.git
cd LBRY-Downloader

# Run the interactive installer
./setup.py

The setup script will:

• ✅ Check and install system dependencies
• ✅ Download and install LBRY SDK (lbrynet) - No blockchain sync required!
• ✅ Set up a Python virtual environment
• ✅ Install Python packages
• ✅ Ask for your download location
• ✅ Configure channels to download from
• ✅ Set download limits
• ✅ Create launcher scripts

Important: The LBRY SDK (lbrynet) requires syncing blockchain headers (not full blocks) to function. On first run:

• Downloads ~1.7 million block headers (takes 5-10 minutes)
• Uses minimal storage (headers only, not full blockchain)
• Subsequent starts are instant
• This is required to verify content claims on the network

This is lighter than Bitcoin's full blockchain sync, but still necessary for the downloader to work.

Manual Install

See LINUX_SETUP.md for detailed manual installation instructions.

Uninstall

To remove LBRY Downloader:

./uninstall.py

Prerequisites

You need to have the LBRY SDK daemon (lbrynet) installed and running:

# The daemon should be accessible at http://127.0.0.1:5279
# Check if it's running:
curl -X POST http://127.0.0.1:5279 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"status","params":{},"id":1}'

To install lbrynet, see: https://lbry.com/get

Configuration

Copy the example config and edit it:

cp config.yaml.example ~/Documents/lbry-downloads/config.yaml
# Edit the file to add your channels

Example configuration:

lbrynet:
  api_url: "http://127.0.0.1:5279"
  timeout_seconds: 60

general:
  base_dir: "~/Documents/lbry-downloads"
  max_workers: 2
  dry_run: false
  include_reposts: false

channels:
  - input: "https://odysee.com/@SomeChannel:1"
    enabled: true
  - input: "lbry://@AnotherChannel#5"
    enabled: true

Finding Channel URLs

Yes, you can get channel info from Odysee! Here's how:

Method 1: From Odysee Website (Easiest)

1. Go to https://odysee.com
2. Search for the channel you want to download from
3. Click on the channel name to go to the channel page
4. Copy the URL from your browser's address bar
   • Example: https://odysee.com/@TechChannel:1
   • Example: https://odysee.com/@DocumentaryFilms:2
5. Paste this URL into your config.yaml

Method 2: From Any Video Page

1. Find a video from the channel you want
2. Click on the channel name below the video
3. Copy the URL from the address bar

Method 3: Using LBRY Desktop App

1. Open the LBRY desktop app
2. Navigate to the channel
3. Right-click on the channel name
4. Select "Copy Link" or look at the URL bar

URL Formats Supported

The tool accepts multiple URL formats:

channels:
  # Odysee URL (most common)
  - input: "https://odysee.com/@ChannelName:1"
    enabled: true
  
  # LBRY URI format
  - input: "lbry://@ChannelName#1"
    enabled: true
  
  # Short form
  - input: "@ChannelName:1"
    enabled: true
  
  # Channel claim ID (most stable)
  - input: "f3b9b2b7c1c3d8e9a1234567890abcdef123456"
    enabled: true

Tip: The Odysee URL is the easiest to find and use. Just copy-paste from your browser!

Per-Channel Download Locations

You can specify a custom download location for each channel:

channels:
  - input: "https://odysee.com/@TechVideos:1"
    enabled: true
    download_path: "/mnt/media/tech"  # Downloads go here instead of base_dir
  
  - input: "https://odysee.com/@Music:1"
    enabled: true
    download_path: "~/Music/LBRY"
  
  - input: "https://odysee.com/@DefaultLocation:1"
    enabled: true
    # No download_path - uses general.base_dir/channels/

Download Limit

Limit how many new downloads per channel (downloads most recent first):

general:
  # Download only 10 most recent items per channel (default)
  download_limit: 10
  
  # Or set to 0 to download everything
  # download_limit: 0

This is useful for:

• Testing: Download just a few files to verify everything works
• Large channels: Gradually sync channels with thousands of videos
• Bandwidth: Control how much data is downloaded per run

Launching the Application

After installation, you can launch LBRY Downloader in several ways:

Method 1: Using the Launcher Script (Recommended)

# Run from install directory
cd ~/Documents/LBRY-Downloader
./bin/lbry-downloader

# Or if you added it to your PATH (see below)
lbry-downloader

Method 2: Using the Virtual Environment

cd ~/Documents/LBRY-Downloader
source venv/bin/activate
python main.py

Method 3: Quick Test Script

cd ~/Documents/LBRY-Downloader
./bin/lbry-test  # Automatically runs with --dry-run

Add to PATH (Run from Anywhere)

Add this to your ~/.bashrc or ~/.zshrc:

export PATH="$HOME/Documents/LBRY-Downloader/bin:$PATH"

Then reload your shell:

source ~/.bashrc  # or source ~/.zshrc

Now you can run lbry-downloader from any directory!

Prerequisites Before Running

Important: Make sure the LBRY daemon is running first:

# Start the daemon
lbrynet start

# Check if it's running
lbrynet status

Usage

# Run with default config
python main.py

# Use custom config
python main.py --config ./my-config.yaml

# Dry run - see what would happen
python main.py --dry-run

Directory Structure

Downloads are organized as:

~/Documents/lbry-downloads/
  config.yaml
  state/
    database.json
    run-history.jsonl
  channels/
    <channel_name>__<channel_claim_id>/
      channel.json
      claims/
        <claim_name>__<claim_id>/
          claim.json
          versions/
            <version_token>/
              <downloaded_file>
              metadata.json
              download.json
              checksums.txt

How It Works

1. Channel Resolution: Converts URLs/URIs to stable channel claim IDs
2. Claim Enumeration: Paginates through all claims in each channel
3. Version Detection: Uses sd_hash to detect updated content
4. Smart Skipping: Only downloads new claims or changed versions
5. Metadata Preservation: Stores normalized metadata beside each file

State Management

The tool maintains state in state/database.json:

• Tracks which channels have been scanned
• Records claim metadata and version history
• Prevents duplicate downloads
• Detects missing files for re-download

Troubleshooting

"Could not connect to LBRY daemon"

Make sure lbrynet is running:

lbrynet start

"Config file not found"

Create a config at the default location or specify a path:

python main.py --config ./config.yaml

Dry run shows no downloads

Check that your channels are enabled and have downloadable content (streams, not just reposts).
