# Draft: Anime-Sama Player Fallback System

## Requirements
- **Mode**: Automatique - essayer tous les players jusqu'à en trouver un qui fonctionne
- **Success Criterion**: Test téléchargement (télécharger un petit chunk pour vérifier)
- **Workflow**: Si le player détecté échoue, essayer VidMoly, SendVid, Sibnet, etc. automatiquement

## Technical Decisions

### Player Priority Order (for Anime-Sama fallback)
1. VidMoly - most reliable
2. SendVid - second most reliable
3. Sibnet - third
4. Lpayer - last (requires Playwright, slower)

### Success Detection
- Download first 10KB of the video
- If successful (200 OK, valid data), consider player working
- Cache which player works for future episodes

### Implementation Approach
1. Add `get_download_link_with_fallback()` method in `AnimeSamaDownloader`
2. Test each player by downloading first 10KB
3. Use first player that returns valid data
4. Cache working player per anime URL/series

## Scope
- INCLUDE: Anime-Sama downloader with automatic player fallback
- INCLUDE: Video URL validation via chunk download test
- INCLUDE: Player caching for performance
- EXCLUDE: Frontend UI changes (backend only)
- EXCLUDE: Other anime sites (Anime-Sama only for now)

## Files to Modify
- `app/downloaders/anime_sites/animesama.py` - Add fallback logic
- `app/downloaders/base.py` - May need base helper method
