Chrome html5视频缓存.事件结束

chrome html5 video buffered.end event

我正在尝试检测视频文件何时完成加载。我使它在firefox和safari上成功工作，但在chrome上，缓冲事件的行为很奇怪。所以,在我的本地主机chrome工作正常，但当我上传到服务器;

  1. 缓冲百分比停止在%50左右，但缓冲%100，

  2. 当页面刷新时，百分比保持在%0，但它继续缓冲。

这是我的javascript

function loaded()
        {
            var v = document.getElementById('myVideo');
            var r = v.buffered;
            var total = v.duration;
            var current=v.currentTime;
            var start = r.start(0);
                    var end = r.end(0); 
            var downloadPercent= Math.round((end / total)*100)
            $("#loadProgress").css('width',downloadPercent+ '%');
                    if(downloadPercent==100){
                $("#preloaderWrapper").fadeOut(function(){
                document.getElementById('myVideo').play();
                clearInterval(ratoteLoad);
                $(this).remove();                   
                    });             
            }       
        }   
            $('#myVideo').bind('progress', function() 
            {
                loaded();
            });

任何想法?谢谢你

试试这个:

myVideoTag = document.getElementById('video');
myVideoTag.addEventListener('progress', function(e) {
    var percent = null;
    // FF4+, Chrome
    if (myVideoTag && myVideoTag.buffered && myVideoTag.buffered.length > 0 && myVideoTag.buffered.end && myVideoTag.duration) {
        percent = myVideoTag.buffered.end(0) / myVideoTag.duration;
    } 
    // Some browsers (e.g., FF3.6 and Safari 5) cannot calculate target.bufferered.end()
    // to be anything other than 0. If the byte count is available we use this instead.
    // Browsers that support the else if do not seem to have the bufferedBytes value and
    // should skip to there. Tested in Safari 5, Webkit head, FF3.6, Chrome 6, IE 7/8.
    else if (myVideoTag && myVideoTag.bytesTotal != undefined && myVideoTag.bytesTotal > 0 && myVideoTag.bufferedBytes != undefined) {
        percent = myVideoTag.bufferedBytes / myVideoTag.bytesTotal;
    }
    if (percent !== null) {
        percent = 100 * Math.min(1, Math.max(0, percent));
        // ... do something with var percent here (e.g. update the progress bar)
    }
}, false);

…从mediaelement.js复制的注释，以及代码，但调整为更容易显示在这里。我省略了Firefox 3.0的代码，因为它不太相关。

PS: thanks to John Dyer for mejs - great stuff;)
