我使用JWPlayer与RTMP流与几个比特率的质量水平的视频。

I am using JWPlayer with RTMP streaming for a video with several bitrate quality levels.

在JWPlayer配置您指定的特质这样的：

In the JWPlayer configuration you specify the qualities like this :

'levels': [
          { bitrate:"2920", width:"1920", file:"videos/sintel-1920.mp4" },
          { bitrate:"2080", width:"1280", file:"videos/sintel-1280.mp4" },
          { bitrate:"2080", width:"720", file:"videos/sintel-720.mp4" },
          { bitrate:"650", width:"480", file:"videos/sintel-480.mp4" },
          { bitrate:"420", width:"320", file:"videos/sintel-320.mp4" }
       ]

我想这是我所必须做的，但后来我看到了在亚马逊的Cloudfront页：

亚马逊的CloudFront的，您可以创建   流媒体分发提供   在不同的丰富的媒体内容   方式比其他Amazon CloudFront的   发行....亚马逊CloudFront的   使用Adobe的FLASH®媒体服务器   增强其流分布.....

Amazon CloudFront lets you create "streaming distributions" to deliver your rich media content in a different way than other Amazon CloudFront distributions.... Amazon CloudFront uses Adobe’s Flash® Media Server to power its streaming distributions.....

.....你也可以配置   流媒体分发使用动态   比特率流。启用时，   此功能可让您存储多个   同一视频的副本，每间codeD   在不同的质量水平。您的   然后分配将自动   调整视频的基于质量   对最终用户的速度   互联网连接。

..... You can also configure your streaming distributions to use dynamic bit-rate streaming. When enabled, this feature lets you store multiple copies of the same video, each encoded at different quality levels. Your distribution will then automatically adjust the quality of your video based on the speed of the end user’s internet connection.

这意味着，在Amazon S3中有两个流分布和动态比特率流分配一个单独的配置。这是正确的？

This implies that in Amazon S3 there are both streaming distributions and a separate configuration for dynamic bit-rate streaming distributions. Is this correct?

这是否意味着我必须启用亚马逊的一项功能，以获得最佳的动态切换 - 或将JWPlayer开关本身就好了？我不清楚这是否是一个独立的断绝侧的功能，将超过JWPlayer工作的更好 - 还是它的工作原理与它一起。

Does this mean I have to enable a feature in Amazon to get the best dynamic switching - or will JWPlayer switch by itself just fine? I'm not clear if this is a separate sever side function that will work better than JWPlayer - or whether it works in conjunction with it.

在此任何进一步的信息？

Any further information on this?

推荐答案

这些文件是始终扑朔迷离。你不必费心，JW玩家需要这种照顾，但你必须上传，当然这些不同的视频格式，以您的启用流桶。

These documents are always confusing. You do not need to bother, JW player takes care of this, but you do have to upload those different video formats to your streaming enabled bucket, of course.
