Question

我希望在第一个播放后的第二个管状实例启动时间超过几秒钟。

我使用2个div将播放器附加到

<div id="player1"></div>
<div id="player2"></div>

我有两个启动管道的脚本。

var options = { 
            videoId: ytid, 
            start: diffInSeconds, 
            mute: false, 
            width: $(window).width(), 
            height:$(window).height(),
            playercount: 1
            };

$('#player' + options.playercount).tubular(options);

它成功启动了第一个管状实例。当第二个实例playercount: 2应该启动时，它只会附加管状容器和盾牌，而不是iframe。

我已添加控制台日志以监控实例是否已加载。

这里是指向jquery.rhtv.init.js的链接（这会调用管状函数）。

这里是修改后的管状JS的链接：

如何设法在第二个实例（以及更多）中加载youtube iframe，最终结果应该是YouTube视频的不间断播放流。每个已经开始播放的视频在哪里播放＆＃39; div应该出现（如在jquery.rhtv.init.js中）

提前谢谢你！

Answer 1

您遇到的问题是由于您如何初始化管状。如果您希望两个玩家使用相同的选项，您将要向玩家添加一个类并使用该类名初始化管状。对于此示例，我们将类名tubular-player添加到容器中，并为每个存在的类初始化管道。

<强> HTML

<div id="player1" class="tubular-player"></div>
<div id="player2" class="tubular-player"></div>

<强>的JavaScript

$('.tubular-player').tubular(options);

Answer 2

管状库默认情况下不支持重新加载其他视频。我做了一些调整，以便可以完成。

以下是工作的jsfiddle链接：

*编辑

以下库现在支持videoFinshed回调和多次管道调用

有电影预告片背靠背播放。

将视频背靠背加载的示例用法

$(function () {
    var videoArr = ["InqU8CLwbPg", "owgrkAQ-Log", "UgBWSPD6MUU"];
    var vidI = 0;

    try {
        $('#wrapper').tubular({
            videoId: videoArr[vidI], 
            mute: false,
            videoFinished: function (state, player) {
                vidI++;
                vidI %= videoArr.length;
                var nextVideo = videoArr[vidI];/* it can directly be loaded from server */
                player.loadVideoById(nextVideo);
            }
        });
    } catch(e) {
    }
});
