Video player Flutter crashes

I want to display a video stored locally on my device using the video player package in Flutter. the problem is that the app crashes when i try to load a video either from youtube using .network or locally using .file. When using .asset the player works perfectly.

class CustomVideoPlayer extends StatefulWidget {
  final List<Uint8List> receivedData;
  const CustomVideoPlayer(this.receivedData);

  @override
  State<CustomVideoPlayer> createState() => _CustomVideoPlayerState();
}

class _CustomVideoPlayerState extends State<CustomVideoPlayer> {
  bool _isLoading = true;
  late VideoPlayerController _controller;
  @override
  void initState() {
    if (_isLoading) {
      final videoProcessed =
          Provider.of<VideoProcessed>(context, listen: false);
      videoProcessed.convertListToVideoFile().then((value) {
        print(videoProcessed.videoFile);
        _controller = VideoPlayerController.network(
            'https://www.youtube.com/watch?v=QC8iQqtG0hg');

        Future.delayed(
          Duration(seconds: 10),
          () {
            _controller.addListener(() {
              setState(() {});
            });
            _controller.setLooping(true);
            _controller.initialize().then((value) {
              setState(() {
                _isLoading = false;
              });
            });
            _controller.play();
          },
        );
      });
    }
    // TODO: implement initState
    super.initState();
  }

  @override
  void dispose() {
    _controller.dispose();
    // TODO: implement dispose
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    final height = MediaQuery.of(context).size.height;
    final width = MediaQuery.of(context).size.width;
    return Container(
      height: height * 0.7497223250647908,
      width: width * 0.6573477447516109,
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(20),
      ),
      child: _isLoading
          ? Center(
              child: CircularProgressIndicator(),
            )
          : ClipRRect(
              borderRadius: BorderRadius.circular(20),
              child: _controller.value.isInitialized
                  ? AspectRatio(
                      aspectRatio: _controller.value.aspectRatio,
                      child: VideoPlayer(_controller))
                  : Container(
                      child: Center(
                        child: Text(
                          'Salut',
                          style: TextStyle(color: Colors.white),
                        ),
                      ),
                    ),
            ),
    );
  }
}```

I added the necessary permission in the AndroidManifest file but I still get the same error.

    Alright, for now I don't use to dipslay the video from a youtube link, I want to fix the error when picking a File from the local stroage using .file method.

    The video I wanna read is coming from a python backend server using websocket as Uint8List. So I have a function taht converts the Uint8List data into a video.mp4 file and then I try to read it. Here is the function that converts it:

    Future<void> convertListToVideoFile() async {
final tempDir = await getTemporaryDirectory();
final tempPath = tempDir.path;

// Concatenate the Uint8List chunks into a single Uint8List
final videoData = Uint8List.fromList(
  videoList.expand((list) => list).toList(),
);

// Create a new File in the temporary directory and write the video data
final file = File('$tempPath/myVideo.mp4');
await file.writeAsBytes(videoData);

videoFile = file;
notifyListeners();

    }

    Video Player Package supports only some valid formats of video, MP4 | HLS.

    The error message suggests that the video player is unable to recognize the format of the video stream.

    To solve the issue use another package, an example could be : youtube_player_flutter
