# Jellyfin SRF Play Plugin

A Jellyfin plugin for accessing SRF Play (Swiss Radio and Television) video-on-demand content and live sports streaming.

## Status

**Beta/Alpha** - This plugin has been tested on two Jellyfin instances and is working. Some clients may experience issues with hardware decoding, which appears to be client-specific behavior.

## Features

- Access to SRF Play VOD content (video-on-demand, no DRM-protected content)
- **Live Sports Streaming** - Watch scheduled sports events (skiing, Formula 1, football, tennis, etc.)
- Support for all Swiss broadcasting units (SRF, RTS, RSI, RTR, SWI)
- Automatic content expiration handling
- Latest and trending content discovery
- Quality selection (Auto, SD, HD)
- HLS streaming support with Akamai token authentication
- Proxy support for routing traffic through alternate gateways
- Smart caching with reduced TTL for upcoming livestreams

## Testing

The plugin includes comprehensive testing:

- **Unit tests** (xUnit framework) for core services
- **API spec validation tests** for all business units (SRF, RTS, RSI, RTR, SWI)
- **Integration testing** - Tested on multiple Jellyfin instances with VOD and live sports streaming

**Run tests:**
```bash
# All tests
dotnet test

# Unit tests only
dotnet test --filter "Category!=Integration&Category!=APISpec"

# API spec tests only
dotnet test --filter "Category=APISpec"

# With coverage
dotnet test --collect:"XPlat Code Coverage"
```

See [Test Documentation](Jellyfin.Plugin.SRFPlay.Tests/README.md) for more details.

### Key Components

1. **API Client**: Handles all HTTP requests to SRF Integration Layer and Play v3 API
2. **Channel**: SRF Play channel with Latest, Trending, and Live Sports folders
3. **Stream Resolver**: Extracts and selects optimal HLS streams with Akamai authentication
4. **Configuration**: User-configurable settings via Jellyfin dashboard
5. **Metadata Cache**: Thread-safe caching with dynamic TTL for livestreams
6. **Content Providers**: Jellyfin integration for series, episodes, images, and media sources
7. **Scheduled Tasks**: Automatic content refresh and expiration management
8. **Service Layer**: Content discovery, expiration handling, stream resolution, and category management

## Important Notes

### Content Limitations

- **No DRM content**: Only non-DRM protected content is accessible (no Widevine/FairPlay)
- **No live TV channels**: Main channels (SRF 1, SRF zwei, SRF info) use DRM and are not supported
- **Sports livestreams supported**: Scheduled sports events (skiing, F1, football, etc.) work without DRM
- **Content expiration**: SRF content has validity periods, plugin tracks and removes expired content
- **Upcoming events**: Sports events appear before they start but require channel refresh to play once live
- **No subtitles**: Subtitle support not currently implemented

### Extensibility

The plugin is designed to support all Swiss broadcasting units:
- **SRF** (Schweizer Radio und Fernsehen - German)
- **RTS** (Radio Télévision Suisse - French)  
- **RSI** (Radiotelevisione svizzera - Italian)
- **RTR** (Radiotelevisiun Svizra Rumantscha - Romansh)
- **SWI** (Swiss World International)

Currently focused on SRF but easily extensible.

## Development

The plugin includes:
- Complete API integration with SRF Play (Integration Layer v2.0 and Play v3)
- **Live sports streaming** with scheduled event detection
- Channel with Latest, Trending, and Live Sports folders
- Metadata providers for series and episodes
- Image fetching and caching
- HLS stream playback with Akamai token authentication
- Automatic content expiration handling
- Scheduled tasks for content refresh
- Smart caching with dynamic TTL for upcoming livestreams

### Known Issues

- Some clients may experience issues with hardware decoding (appears to be client-specific)
- Some edge cases may need additional handling
- Performance optimization may be needed for very large content catalogs

This plugin was developed with inspiration from the excellent [Kodi SRG SSR addon](https://github.com/goggle/script.module.srgssr) by [@goggle](https://github.com/goggle). The Kodi addon served as a fantastic reference for understanding the SRG SSR API structure, authentication mechanisms, and handling of scheduled livestreams.
