Readme
Supported versions
| Platform | Version | | ------------ | ------- | | React Native | 0.79 | | Android | 7+ | | iOS | 15.1+ |
Installation
Add the package to your npm dependencies
npm install expo-libvlc-playerBare React Native projects
For bare React Native projects, you must ensure that you have installed and configured the expo package.
Configure for Android
No additional configuration necessary.
Black screen issue
On Android, the libvlcjni player detaches from the View when surfaces are destroyed after switching screens.
This causes nothing to be displayed when coming back to the player as native resources are released automatically.
The current workaround attaches the View once surfaces are created but this results in a brief black screen.
Configure for iOS
Run npx pod-install after installing the npm package.
Local network privacy
On iOS, the MobileVLCKit player seems to interact with the local network when playing media from external sources.
Starting in iOS 14, a clear message must be provided to the NSLocalNetworkUsageDescription key in the Info.plist file.

Audio playback issue
On iOS, the MobileVLCKit player experiences a small audio delay when resuming or muting media playback.
This might be related to the internal clock used by the library core causing inaccurate position/time values.
