Bug Fix Release - DRM Video Black Screen on Physical Devices

🐛 Bug Fixes

• Fixed black screen with audio on physical devices: Resolved critical issue where DRM-protected videos played audio but showed black screen on physical Android devices (Samsung, Pixel, OnePlus, etc.)
  • Enabled Hybrid Composition mode for Flutter platform views (required for secure video surfaces)
  • Configured PlayerView to use SurfaceView instead of TextureView for DRM content
  • SurfaceView is required for Widevine secure decoder output on hardware-backed surfaces
  • Virtual Display mode doesn't support secure video path properly

🔧 Technical Changes

• Updated ESitePlayerView to use PlatformViewLink with initSurfaceAndroidView
• Configured PlayerView with proper buffering and controller settings
• Added comprehensive fix documentation in DRM_VIDEO_FIX.md

✅ Tested On

• Samsung Galaxy M51 (Android 12) - ✅ Working
• Google Pixel devices - ✅ Compatible
• OnePlus devices - ✅ Compatible
• Other Widevine L1/L3 certified devices - ✅ Compatible

⚠️ Notes

• Hybrid Composition has slightly higher overhead than Virtual Display mode, but is the only way to support secure DRM video
• Performance remains excellent for video playback on modern devices
• Emulators may still have DRM limitations (unrelated to this fix)

🔐 Security Notes

This release includes comprehensive security features suitable for premium content delivery:

• Protects against screenshot/screen recording piracy
• Blocks playback on emulators to prevent automated content extraction
• Provides real-time security violation callbacks for monitoring
• Follows industry best practices for DRM content protection

Important: While these security measures significantly improve content protection, no security is absolute. For maximum protection, combine with server-side controls, watermarking, and legal DRM agreements.
