# TVH2Jellyfin

Transfer completed recordings from TVHeadend to Jellyfin media storage.

## Features

- Monitors TVHeadend for completed recordings via JSON API
- Pulls files from TVHeadend server via SCP
- Writes to local Jellyfin media directory (Docker volume)
- Organizes files by show name: `{dest_path}/{show_name}/{episode}.ts`
- Deletes recordings from TVHeadend after successful transfer
- Tracks transferred files to avoid duplicates
- Runs as a Docker container
- Dry run mode for testing without making changes

## Prerequisites

1. SSH key access from the Docker host to the TVHeadend server
2. TVHeadend API access (username/password)
3. Docker and Docker Compose

## Setup

### 1. Generate SSH Key (if needed)

```bash
ssh-keygen -t rsa -b 4096 -f ~/.ssh/tvh2jellyfin
ssh-copy-id -i ~/.ssh/tvh2jellyfin.pub user@tvheadend-server
```

### 2. Configure Environment

Copy the example environment file and edit with your settings:

```bash
cp .env.example .env
```

Edit `.env` with your configuration:

```bash
# TVHeadend server
TVH_HOST=192.168.1.100
TVH_PORT=9981
TVH_USER=admin
TVH_PASS=your_password

# SSH user on TVHeadend server (defaults to TVH_USER)
TVH_SSH_USER=admin

# SSH key path on Docker host
SSH_KEY_PATH=~/.ssh/tvh2jellyfin

# Jellyfin media library path on Docker host
JELLYFIN_MEDIA_PATH=/mnt/jellyfin/tv

# Poll interval in seconds (default: 300 = 5 minutes)
POLL_INTERVAL=300
```

### 3. Build and Run

```bash
docker compose up -d
```

### 4. View Logs

```bash
docker compose logs -f
```

## Configuration Options

| Variable | Description | Default |
|----------|-------------|---------|
| `TVH_HOST` | TVHeadend server hostname/IP | `localhost` |
| `TVH_PORT` | TVHeadend HTTP port | `9981` |
| `TVH_USER` | TVHeadend API username | (required) |
| `TVH_PASS` | TVHeadend API password | (required) |
| `TVH_SSH_USER` | SSH username for TVHeadend server | `TVH_USER` |
| `SSH_KEY_PATH` | Path to SSH private key on Docker host | `~/.ssh/id_rsa` |
| `JELLYFIN_MEDIA_PATH` | Jellyfin media path on Docker host | `/mnt/jellyfin/tv` |
| `POLL_INTERVAL` | Seconds between checks | `300` |
| `LOG_LEVEL` | Logging level | `INFO` |
| `DRY_RUN` | Test mode (no transfers/deletions) | `false` |

```

1. Container queries TVHeadend API for completed recordings
2. Downloads files via SCP from TVHeadend server
3. Writes to local Jellyfin media volume
4. Removes recording from TVHeadend via API

## File Organization

Recordings are organized by show name:

```
/mnt/jellyfin/tv/
├── Show Name/
│   ├── Show Name - Episode Title.ts
│   └── Show Name - 2024-01-15 2000.ts  (if no episode title)
└── Another Show/
    └── Another Show - Episode.ts
```

## Dry Run Mode

Test what would happen without actually transferring or deleting anything:

```bash
DRY_RUN=true docker compose up
```

In dry run mode:
- Connects to TVHeadend API and lists completed recordings
- Shows what files would be transferred and where
- Shows which recordings have already been transferred
- Does NOT connect via SSH
- Does NOT transfer any files
- Does NOT delete recordings from TVHeadend
- Does NOT update the state file
- Exits after a single check (no polling loop)

Example output:
```
[DRY RUN] Starting sync cycle...
[DRY RUN] Found 2 new recording(s) to transfer
[DRY RUN] Would process: The News - Evening Edition
[DRY RUN]   Source: /recordings/The News - Evening Edition.ts
[DRY RUN]   Destination: /media/tv/The News/The News - Evening Edition.ts
[DRY RUN]   Size: 1250.5 MB
[DRY RUN]   Would delete from TVHeadend after transfer
```

## Development

### Install Dependencies

```bash
python -m venv venv
source venv/bin/activate
pip install -e ".[dev]"
```

### Run Tests

```bash
pytest
```

### Run Locally

```bash
export TVH_HOST=...
export TVH_USER=...
export TVH_PASS=...
export TVH_SSH_USER=...
export DEST_PATH=/path/to/destination
python -m tvh2jellyfin.main
```

## Troubleshooting

### SSH Connection Issues

Ensure the SSH key has correct permissions:
```bash
chmod 600 ~/.ssh/tvh2jellyfin
```

Test SSH connection manually:
```bash
ssh -i ~/.ssh/tvh2jellyfin user@tvheadend-server
```

### TVHeadend API Issues

Test API access:
```bash
curl -u admin:password http://tvheadend:9981/api/serverinfo
```

### Permission Issues

Ensure the Jellyfin media directory is writable:
```bash
touch /mnt/jellyfin/tv/.test && rm /mnt/jellyfin/tv/.test
```

### View Transfer History

The state file (`data/state.json`) contains all transfer records.
