是否有可能在HTML5中获得视频/图像的下载进度？ [英] Is it possible to get download progress of video/image in HTML5?

问题描述

几乎每个闪存播放器都有一个选项可以显示下载到客户端的缓冲区（或总视频的百分比）。目前，我没有看到它在任何HTML5视频播放器的实现。

我想要解决的真正的问题是有一种方式知道下载％资产（图像/瑞士法郎/视频无论）。在Flash中使用MovieClipLoader和bytesLoaded属性很简单。

有没有在HTML / HTML5 / Javascript（不依赖于Flash）的情况下做到这一点的方法？

谢谢！

解决方案

请参阅缓冲属性，但请注意，有（据我所知）没有完整的实现HTML 5的视频API，并且它可能会改变，所以支持规范的其他部分的浏览器可能不支持 buffered 。

Almost every flash player has an option to display how much of buffer (or % of total video) is downloaded to the client. At the moment I don't see it in any implementation of html5 video player.

The real problem I am trying to solve is to have a way of knowing % of downloaded asset (image/swf/video whatever). In flash its easy by using MovieClipLoader and bytesLoaded property.

Is there any way of doing it in HTML/HTML5/Javascript (without relying on Flash) ?

Thanks!

解决方案

See the buffered property but be aware that there are (as far as I know) no complete implementations of the HTML 5 video API, and that it is subject to change anyway, so browsers which support other parts of the spec may not support buffered.
