I'm using flutter video_player
package to play a list of video.
List sourceList;
sourceList = [
{
"size": 69742504,
"name": "lucky-roulette.mp4",
"mimetype": "video/mp4",
},
{
"size": 69742504,
"name": "BigBuckBunny.mp4",
"mimetype": "video/mp4",
}
];
I've checked out this issue, and did some custom codes upon it.
void play() {
log.fine("Now playing: $_nowPlayingUrl");
_adController = VideoPlayerController.network(_nowPlayingUrl);
_adController.initialize().then((_) => setState(() {}));
_adController.play();
_adController.addListener(checkIfVideoFinished);
}
void checkIfVideoFinished() {
if (_adController == null ||
_adController.value == null ||
_adController.value.position == null ||
_adController.value.duration == null) return;
if (_adController.value.position.inSeconds ==
_adController.value.duration.inSeconds) {
_adController.removeListener(checkIfVideoFinished);
_adController.dispose();
// Change _nowPlayingIndex
setState(() {
_nowPlayingIndex = (_nowPlayingIndex + 1) % _totalIndex;
});
play();
}
}
But use this code snippet would send out an exception Another exception was thrown: A VideoPlayerController was used after being disposed.
Is there a better way to play and loop a list of video in Flutter?
Recently I tested video list example. please check the source in github FlutterVideoListSample. I think the video widget must be disposed.
In my case, I clear the old VideoPlayerController before initialize it. And I don't use chewie
plugin that make new page in entering fullscreen so cannot handle the next video widget.
video_player: '>=0.10.11+1 <2.0.0'
some code in FlutterVideoListSample
VideoPlayerController _controller;
void _initializeAndPlay(int index) async {
print("_initializeAndPlay ---------> $index");
final clip = _clips[index];
final controller = VideoPlayerController.asset(clip.videoPath());
final old = _controller;
if (old != null) {
old.removeListener(_onControllerUpdated);
old.pause(); // mute instantly
}
_controller = controller;
setState(() {
debugPrint("---- controller changed");
});
controller
..initialize().then((_) {
debugPrint("---- controller initialized");
old?.dispose();
_playingIndex = index;
controller.addListener(_onControllerUpdated);
controller.play();
setState(() {});
});
}
