[]调用JSMpeg会闪屏

Laya.init(720,1280,WebGL);
Stat.show();
//设置水平对齐
Laya.stage.alignH = Stage.ALIGN_CENTER;
//设置垂直对齐
Laya.stage.alignV = Stage.ALIGN_MIDDLE;
//设置适配模式
Laya.stage.scaleMode = Stage.SCALE_EXACTFIT;
//设置横竖屏
Laya.stage.screenMode = Stage.SCREEN_VERTICAL;

__JS__('var canvas = document.getElementById("layaCanvas")');
__JS__('var url = "ws://xxx.xxx.xx.xx:xxxx"');
__JS__('var player = new JSMpeg.Player(url, {canvas: canvas})');
