如果JWPlayer中的主服务器失败，我该如何使用javascript自动切换到备用直播流? [英] How do I use javascript to automatically switch to a backup live stream if primary fails in JWPlayer?

问题描述

我正在尝试编写一个JavaScript函数，该函数将使JW Player的实例在发生错误(例如:主编码器出现故障)时自动从主实时HLS流切换到备用实时HLS流. /p>

我到目前为止所拥有的:

<div id="myElement">Loading the player...</div>

var playerInstance = jwplayer("myElement");
playerInstance.setup({
    file: "http://server/primary/playlist.m3u8",
    width: 640,
    height: 360,
    title: 'Basic Video Embed',
    description: 'work damn you',
});

jwplayer('myElement').on('error', function(event) {
    var prime = document.getElementById("myElement").innerHTML;
    var backup = prime.replace("http://server/primary/playlist.m3u8", "http://server/backup/playlist.m3u8");
    document.getElementById("myElement").innerHTML = backup;
});

在我的测试中，这不起作用(当主要停止时，该功能不执行，播放器旋转).我已经尝试过('错误')，('缓冲')，('空闲')，所有操作都具有相同的结果.

我将在此代码中进行哪些更改以实现自己的目标?欢迎任何帮助.

解决方案

我们的一位工程师刚刚撰写了一篇有关此解决方案的精彩博客文章，其中包括代码示例:

var playerInstance = jwplayer("myElement");
playerInstance.setup({
    file: "http://server/primary/playlist.m3u8",
    width: 640,
    height: 360,
    title: 'Basic Video Embed',
    description: 'work damn you',
});

jwplayer('myElement').on('error', function(event) {
    var prime = document.getElementById("myElement").innerHTML;
    var backup = prime.replace("http://server/primary/playlist.m3u8", "http://server/backup/playlist.m3u8");
    document.getElementById("myElement").innerHTML = backup;
});

In my testing this doesn't work (when the primary stops, the function doesn't execute, the player just spins). I've tried ('error'), ('buffering'), ('idle'), all with the same results.

What would I change in this code to accomplish my goal? Any help is welcome.

解决方案

One of our engineers just wrote a great blog post about this solution, including code samples: https://www.jwplayer.com/blog/building-insights-video-experience/

insightsPlayer.on('error', function(event) {
  playStream('error');
});

insightsPlayer.on('complete', function(event) {
  playStream(currentStream);
});

If there’s an error, the player switches to the error file. The video is a 10-second still that displays an informational slide. Once that completes, the player tries to play the previously determined currentStream.
