### 🔧 **Implementation Details**
|
||
|
||
#### API Response Changes
|
||
```typescript
|
||
// OLD: Transcoding redirect
|
||
{
|
||
type: 'fallback',
|
||
url: '/api/stream/123', // Redirects to transcode
|
||
warning: 'Limited playback features'
|
||
}
|
||
|
||
// NEW: Local player guidance
|
||
{
|
||
type: 'local-player',
|
||
supportLevel: 'local-player-required',
|
||
url: '/api/stream/direct/123',
|
||
action: 'launch-local-player',
|
||
recommendedPlayers: ['vlc', 'elmedia', 'potplayer'],
|
||
streamInfo: {
|
||
contentType: 'video/x-matroska',
|
||
acceptRanges: 'bytes',
|
||
supportsSeek: true
|
||
}
