每當播放列表中的下一個項目被加載到jwplayer中時，就會動態更改相關視頻6.8

Question

有沒有一種方法可以在播放列表的下一個項目加載時動態更改相關視頻？有點像你可以自己處理播放列表。

我願做這樣的事情：

player.onPlaylistItem(function(e) { 

    player.load([{related: { 
     file: "/assets/related.xml" 
    }]); 

});

這根柺杖使用介質ID來完成。

Media ID Replacement 

The Media ID Replacement feature allows JW Player to dynamically construct URLs to related videos RSS feeds. This is required in two situations: 

    If you have a playlist with multiple videos and want to display related videos for each item. 
    If you set the onclick option to play and want to display related videos of related videos. 

Here is an example embed using a simple playlist with 2 items: 

    jwplayer("container").setup({ 
    playlist: [{ 
     file: "/videos/12345.mp4", 
     mediaid: "12345" 
    },{ 
     file: "/videos/67890.mp4", 
     mediaid: "67890" 
    }], 
    related: { 
     file: "/related/MEDIAID.xml" 
    } 
}); 

For the first item in the playlist, JW Player will request the RSS feed /related/12345.xml. For the second item, JW Player will request the feed /related/67890.xml. 

If the items in these RSS feeds also contain a mediaid (using the guid element), JW Player is able to in turn construct a related videos URL and display related videos of these related videos: 

<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/"> 
    <channel> 
    <item> 
     <title>Big Buck Bunny</title> 
     <guid isPermalink="false">28839</guid> 
     <media:thumbnail url="http://example.com/thumbs/28839.jpg"/> 
     <media:content url="http://example.com/videos/28839.mp4" type="video/mp4" /> 
    </item> 

    <item> 
     <title>Elephant's Dream</title> 
     <guid isPermalink="false">8791</guid> 
     <media:thumbnail url="http://example.com/thumbs/8791.jpg"/> 
     <media:content url="http://example.com/videos/8791.mp4" type="video/mp4" /> 
    </item> 
    </channel> 
</rss>
