Hi @Hoang_Dang ,

I’ve reviewed your video playback issue and identified two adjustments that should resolve the black screen problem.

## What I Found

1. **Missing playback trigger** : Since you’ve set `autoplay = false`, the video loads but doesn’t start playing automatically.

2. **Video format compatibility** : ShakaPlayer requires adaptive streaming formats like DASH manifests rather than direct MP4 files.

## Suggested Changes

Please try these modifications:

**1. Add the play() call**

In your `initVideoPlayer` function, add this line after loading the content:

```javascript
await shakaPlayer.current.load(content, true);
console.log('✅ Shaka content loaded');

// Add this line:
await shakaPlayer.current.play();
console.log('▶️ Playback started');

```

**2. Use a compatible video format**

Replace your current video URL with this DASH format example:

```javascript
const content = {
  secure: false,
  uri: 'https://storage.googleapis.com/shaka-demo-assets/angel-one/dash.mpd', // DASH format example
  drm_scheme: '',
  drm_license_uri: '',
};

```

Would you be able to give these changes a try? Let me know if you run into any other issues.

Regards,  
Aishwarya
