flutter flutter_vlc_player播放视频设置循环播放失效、初始化后获取不到视频宽高

news 2025/7/3 5:30:53

插件：flutter_vlc_player: ^7.4.3

问题1：设置循环播放_controller.setLooping(true);无用。

解决方法：

//vlcPlayer设置循环播放失效，以这种方式失效循环播放
_setLoopListener() async {if (_videoController!.value.hasError) {esLoadingToast('视频加载失败');} else {if (_videoController!.value.playingState == PlayingState.ended) {_videoController!.stop().then((_) => _videoController!.play());}}
}initState(){
super.initState();
_videoController!.addListener(_setLoopListener);
}

问题2：播放器初始化完成但是元数据还未解析完成，导致无法获取到视频的宽高

_videoController?.addOnInitListener((){if (_videoController!.value.isInitialized) {//已经初始化final size = _videoController!.value.size;//打印出来获取到0print('width= ${size.with}');//打印出来获取到1print('aspectRatio= ${_videoController!.value.aspectRatio}');}
});

解决方法：

_videoController?.addOnInitListener((){_waitForVideoSize();
});//视频虽然初始化完成但是元数据还未解析完成，使用轮询直到获取到宽高
_waitForVideoSize() {if (_videoController!.value.isInitialized) {int _attempt = 0;Timer.periodic(Duration(milliseconds: 300), (timer) {final size = _videoController!.value.size;if (size.width > 0 && size.height > 0) {timer.cancel(); // 停止轮询_totalDuration = _videoController!.value.duration;_videoController!.setVolume(0);_videoController!.setLooping(true);//VlcPlayer对于网络视频有时生效，有时失败double _videoWidth = _videoController!.value.size.width;double _videoHeight = _videoController!.value.size.height;print('_videoWidth= $_videoWidth  _videoHeight= $_videoHeight');print('aspectRatio= ${_videoController!.value.aspectRatio}');_sizeWidth = _videoWidth;_sizeHeight = _videoHeight;double _aspectRatio = _videoHeight / _videoWidth;_logic.videoAspectRatio = _aspectRatio;print('videoAspectRatio===== ${_logic.videoAspectRatio}');_videoController!.play();_isVideoInit = true;setState(() {});}else if(_attempt>= 200){timer.cancel();}});}
}
