VideoPlayerController's isInitialized state is turning to false, when network is gone for a while.

[Blacktaler]

I'm using VideoPlayer plugin and there are issues with network. For example, I initialize the video in initState, video starts to play, VideoPlayerController buffers 1-3 minutes of the video. I turn off the network(wifi or mobile data). Video plays until the buffered position(3 minutes). If I do not turn on the network while that time, VideoPlayerController's isInitialized state turns false. After that, video will not continue even if the network is back.

Steps to reproduce:

1) Declare VideoPlayerController as variable, initialize in initState method. 2) Use VideoPlayer widget inside the body, give the videoPlayerController to the widget. 3) Turn off the network for a while,(until the videoPlayerController gets reset). 4) Turn on the network, video will not continue to play.

it's happening with all videos, just play the video when wifi is turned on, then play the video until the buffered position, then it will stop showing the video and controller's isInitialized value becomes false, then even if your network is returned it will not continue playing.

Anyways, I was trying to check and re initialize when the controller becomes uninitialized, but after once it does not even message that controller has become unInitialized.

Please fix at least one of these errors above, thanks in advance.

Hi @Blacktaler, what version of video_player are you using? What device(s) are you seeing this on? And what issue did you want to reply to?

Hi @Blacktaler, what version of video_player are you using? What device(s) are you seeing this on? And what issue did you want to reply to?

In any android device it's happening. I'm using 2.7.2-version of video_player plugin. I wanted to reply in this #107802 issue issue

I checked this using the sample code below (which has VideoProgressIndicator to see the cached video part more easily).

• On Flutter iOS which uses AVPlayer underlying, the issue is not reproduced.
• On Flutter Android, the issue is reproduced. Once the network is resumed, the video does not continue playing. I also checked this using ExoPlayer Android native sample code here, and the issue is not there. The playback button will turn into "pause" state automatically when turning off network. Once I turn network on again, press Play button, the video continue playing as desired.

Reproduced the issue with the latest package version video_player_android: ^2.4.14.

Flutter sample code

```dart import 'dart:async'; import 'package:flutter/material.dart'; import 'package:video_player/video_player.dart'; void main() => runApp(const VideoPlayerApp()); class VideoPlayerApp extends StatelessWidget { const VideoPlayerApp({super.key}); @override Widget build(BuildContext context) { return const MaterialApp( title: 'Video Player Demo', home: VideoPlayerScreen(), ); } } class VideoPlayerScreen extends StatefulWidget { const VideoPlayerScreen({super.key}); @override State createState() => _VideoPlayerScreenState(); } class _VideoPlayerScreenState extends State { late VideoPlayerController _controller; late Future _initializeVideoPlayerFuture; @override void initState() { super.initState(); // Create and store the VideoPlayerController. The VideoPlayerController // offers several different constructors to play videos from assets, files, // or the internet. _controller = VideoPlayerController.networkUrl( Uri.parse('http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4'), ); // Initialize the controller and store the Future for later use. _initializeVideoPlayerFuture = _controller.initialize(); // Use the controller to loop the video. _controller.setLooping(true); } @override void dispose() { // Ensure disposing of the VideoPlayerController to free up resources. _controller.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Butterfly Video'), ), // Use a FutureBuilder to display a loading spinner while waiting for the // VideoPlayerController to finish initializing. body: FutureBuilder( future: _initializeVideoPlayerFuture, builder: (context, snapshot) { if (snapshot.connectionState == ConnectionState.done) { // If the VideoPlayerController has finished initialization, use // the data it provides to limit the aspect ratio of the video. return Stack( alignment: Alignment.bottomCenter, children: [ AspectRatio( aspectRatio: _controller.value.aspectRatio, // Use the VideoPlayer widget to display the video. child: VideoPlayer(_controller), ), VideoProgressIndicator( _controller, allowScrubbing: true, colors: VideoProgressColors(playedColor: Theme.of(context).primaryColor), ), ], ); } else { // If the VideoPlayerController is still initializing, show a // loading spinner. return const Center( child: CircularProgressIndicator(), ); } }, ), floatingActionButton: FloatingActionButton( onPressed: () { // Wrap the play or pause in a call to `setState`. This ensures the // correct icon is shown. setState(() { // If the video is playing, pause it. if (_controller.value.isPlaying) { _controller.pause(); } else { // If the video is paused, play it. _controller.play(); } }); }, // Display the correct icon depending on the state of the player. child: Icon( _controller.value.isPlaying ? Icons.pause : Icons.play_arrow, ), ), ); } } ```
