jwplayer :若请求不到流,则页面一直转圈请求效果
思路: 利用jwplayer onPlay(播放) 、onError(出错)事件。
页面:背景图为黑色,嵌入一张背景为黑色的 git 动态图,加载页面时隐藏。
流程:若进入到onPlay 方法,则说明能正常播放,则 黑色背景与 gif动态图隐藏。
若进入到onError方法,则说明播放有问题,则 黑色背景与 gif动态图显示,并且不断地调用初始化方法。
关键代码如下:
var thePlayer; //保存当前播放器以便操作 var playpath = ""; var callback = function () { console.log("callback");};//定义一个回调方法 var initPlayer = function(playpath) { thePlayer = jwplayer('container_video').setup({ flashplayer: 'jwplayer/jwplayer.flash.swf', file: playpath, width: "100%", height: "", aspectratio:'16:9', allowfullscreen:true, allowscriptaccess:"always", autostart:true, enablejs:true, bufferlength:1, rotatetime:1, dock: false, bwfile:playpath, rtmp: { subscribe: true },events: { onComplete: function () { console.log("播放结束!!!"); }, onVolume: function () { console.log("声音大小改变!!!"); }, onReady: function () { console.log("准备就绪!!!"); }, onPlay: function () { console.log("开始播放!!!"); $("#mygif").hide(); $("#myblack").hide(); }, onPause: function () { console.log("暂停!!!"); }, onBufferChange: function () { console.log("缓冲改变!!!"); }, onBufferFull: function () { console.log("视频缓冲完成!!!"); }, onError: function (obj) { console.log("播放器出错!!!" + obj.message); $("#mygif").show(); $("#myblack").show(); initPlayer(playpath); }, onFullscreen: function (obj) { if (obj.fullscreen) { console.log("全屏"); } else { console.log("非全屏"); } }, onMute: function (obj) { console.log("静音/取消静音") } } }); }
