在flex中缓存flv数据

[英]caching flv data in flex

原文 2011-09-09 16:50:18 1 1 flash/ apache-flex/ caching/ flv

I am developing an eLearning application in Flex which shows flv movies hosted on a webserver. 我正在Flex中开发一个电子学习应用程序，该应用程序显示托管在网络服务器上的flv电影。 If the app has many simultaneous users the download demand is quite high because a lot of users need to download the (same) movie(s). 如果应用程序有多个同时用户，则下载需求很高，因为很多用户需要下载（相同）电影。 Is there a way I can precache this data in my flex client like storing it in the browsercache or something so that for later sessions the bandwidth demand is less high? 有没有一种方法可以将我的数据预缓存在我的Flex客户端中，例如将其存储在浏览器缓存中，还是在以后的会话中带宽需求不那么高？

Thanks, Martijn 谢谢，马丁

Browsers will naturally cache the flvs. 浏览器自然会缓存flv。 Make sure you don't have no-cache headers set on the flvs. 确保没有在flv上设置无缓存头。 However, the cache can fill up, and nothing prevents users from clearing their browser cache. 但是，缓存可以填满，并且没有什么可以阻止用户清除其浏览器缓存。

A better solution in my opinion would be to host the flvs on something like amazon cloud front . 我认为，更好的解决方案是将flv托管在类似Amazon Cloud Front的平台上。

Edit Also, you should consider moving from flv to h.264 as it has been supported since Flash Player 9 (version 9,0,115,0) Update 3 and has much better compression than flvs. 编辑此外，您应该考虑从flv迁移到h.264，因为自Flash Player 9（版本9,0,115,0）Update 3起已支持它，并且压缩比flvs好得多。
