# Media Server

A REST API server for controlling system media playback on Windows, Linux, macOS, and Android.

## Features

- Control any media player via system-wide media transport controls
- Play/Pause/Stop/Next/Previous track
- Volume control and mute
- Seek within tracks
- Get current track info (title, artist, album, artwork)
- Token-based authentication
- Cross-platform support

## Requirements

- Python 3.10+
- Platform-specific dependencies (see below)

## Installation

### Windows

```bash
pip install -r requirements.txt
```

Required packages: `winsdk`, `pywin32`, `pycaw`, `comtypes`

### Linux

```bash
# Install system dependencies
sudo apt-get install python3-dbus python3-gi libdbus-1-dev libglib2.0-dev

pip install -r requirements.txt
```

### macOS

```bash
pip install -r requirements.txt
```

No additional dependencies - uses built-in `osascript`.

### Android (Termux)

```bash
# In Termux
pkg install python termux-api
pip install -r requirements.txt
```

Requires Termux and Termux:API apps from F-Droid.

## Quick Start

1. Generate configuration with API token:
   ```bash
   python -m media_server.main --generate-config
   ```

2. View your API token:
   ```bash
   python -m media_server.main --show-token
   ```

3. Start the server:
   ```bash
   python -m media_server.main
   ```

4. Test the connection:
   ```bash
   curl http://localhost:8765/api/health
   ```

5. Test with authentication:
   ```bash
   curl -H "Authorization: Bearer YOUR_TOKEN" http://localhost:8765/api/media/status
   ```

## Configuration

Configuration file locations:
- Windows: `%APPDATA%\media-server\config.yaml`
- Linux/macOS: `~/.config/media-server/config.yaml`

### config.yaml

```yaml
host: 0.0.0.0
port: 8765
api_token: your-secret-token-here
poll_interval: 1.0
log_level: INFO
```

### Environment Variables

All settings can be overridden with environment variables (prefix: `MEDIA_SERVER_`):

```bash
export MEDIA_SERVER_HOST=0.0.0.0
export MEDIA_SERVER_PORT=8765
export MEDIA_SERVER_API_TOKEN=your-token
export MEDIA_SERVER_LOG_LEVEL=DEBUG
```

### Configuring Scripts

Add scripts in your `config.yaml`:

```yaml
scripts:
  lock_screen:
    command: "rundll32.exe user32.dll,LockWorkStation"
    label: "Lock Screen"
    description: "Lock the workstation"
    timeout: 5
    shell: true

  shutdown:
    command: "shutdown /s /t 0"
    label: "Shutdown"
    description: "Shutdown the PC immediately"
    timeout: 10
    shell: true

  restart:
    command: "shutdown /r /t 0"
    label: "Restart"
    description: "Restart the PC"
    timeout: 10
    shell: true

  hibernate:
    command: "shutdown /h"
    label: "Hibernate"
    description: "Hibernate the PC"
    timeout: 10
    shell: true

  sleep:
    command: "rundll32.exe powrprof.dll,SetSuspendState 0,1,0"
    label: "Sleep"

### Configuring Callbacks

Callbacks are optional commands executed after media actions. Add them in your `config.yaml`:

```yaml
callbacks:
  # Media control callbacks (run after successful action)
  on_play:
    command: "echo Play triggered"
    timeout: 10
    shell: true

  on_pause:
    command: "echo Pause triggered"
    timeout: 10
    shell: true

  on_stop:
    command: "echo Stop triggered"
    timeout: 10
    shell: true

  on_next:
    command: "echo Next track"
    timeout: 10
    shell: true

  on_previous:
    command: "echo Previous track"
    timeout: 10
    shell: true

  on_volume:
    command: "echo Volume changed"
    timeout: 10
    shell: true

  on_mute:
    command: "echo Mute toggled"
    timeout: 10
    shell: true

  on_seek:
    command: "echo Seek triggered"
    timeout: 10
    shell: true

  # Turn on/off/toggle (callback-only actions, no default behavior)
  on_turn_on:
    command: "echo PC turned on"
    timeout: 10
    shell: true

  on_turn_off:
    command: "rundll32.exe user32.dll,LockWorkStation"
    timeout: 5
    shell: true

## Running as a Service

### Windows Task Scheduler (Recommended)

Run in **Administrator PowerShell** from the project root:

```powershell
.\media_server\service\install_task_windows.ps1
```

To remove the scheduled task:

```powershell
Unregister-ScheduledTask -TaskName "MediaServer" -Confirm:$false
```

### Windows Service

Install:
```bash
python -m media_server.service.install_windows install
```

Start/Stop:
```bash
python -m media_server.service.install_windows start
python -m media_server.service.install_windows stop
```

Remove:
```bash
python -m media_server.service.install_windows remove
```

### Linux (systemd)

Install:
```bash
sudo ./service/install_linux.sh install
```

Enable and start for your user:
```bash
sudo systemctl enable media-server@$USER
sudo systemctl start media-server@$USER
```

View logs:
```bash
journalctl -u media-server@$USER -f
```

## Command Line Options

```
python -m media_server.main [OPTIONS]

Options:
  --host TEXT          Host to bind to (default: 0.0.0.0)
  --port INTEGER       Port to bind to (default: 8765)
  --generate-config    Generate default config file and exit
  --show-token         Show current API token and exit
```

## Security Recommendations

1. **Use HTTPS in production** - Set up a reverse proxy (nginx, Caddy) with SSL
2. **Strong tokens** - Default tokens are 32 random characters; don't use weak tokens
3. **Firewall** - Only expose the port to trusted networks
4. **Secrets management** - Don't commit tokens to version control

## Supported Media Players

### Windows
- Spotify
- Windows Media Player
- VLC
- Groove Music
- Web browsers (Chrome, Edge, Firefox)
- Any app using Windows Media Transport Controls

### Linux
- Any MPRIS-compliant player:
  - Spotify
  - VLC
  - Rhythmbox
  - Clementine
  - Web browsers
  - MPD (with MPRIS bridge)

### macOS
- Spotify
- Apple Music
- VLC (partial)
- QuickTime Player

### Android (via Termux)
- System media controls
- Limited seek support

## Troubleshooting

### "No active media session"
- Ensure a media player is running and has played content
- On Windows, check that the app supports media transport controls
- On Linux, verify MPRIS with: `dbus-send --print-reply --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames | grep mpris`

### Permission errors on Linux
- Ensure your user has access to the D-Bus session bus
- For systemd service, the `DBUS_SESSION_BUS_ADDRESS` must be set correctly

### Volume control not working
- Windows: Run as administrator if needed
- Linux: Ensure PulseAudio/PipeWire is running
