网络视频缓冲 [英] Web Video Buffering

问题描述

只是一个普遍的问题-是否存在一个嵌入式播放器(Flash或其他)，它无需真正开始播放视频就可以进行下载/缓冲?

我的想法是:在网络上不断播放视频使我发疯.播放器似乎永远无法下载/缓冲到足以保持播放前的状态.

如果播放器在您打开页面后立即开始下载视频，那么当您阅读宣传内容和评论并关闭所有愚蠢的广告时，就需要缓冲足够的视频以流畅播放并保持领先地位.希望是.

好主意?馊主意?

Just a general question - is there an embeddable player (Flash or otherwise) that does its download/buffering without having to actually start playing the video?

My thinking is this: the stop-n-go playing of videos on the web drives me crazy. The players never seem to be able to download/buffer enough to keep ahead of the playing.

If a player started downloading the video as soon as you opened the page, by the time you read the blurbs and reviews and dismissed all the stupid ads, there''d be enough video alreday buffered to play smoothly and keep well ahead. Hopefully.

Good idea? Bad idea? Even possible?

推荐答案

存在的问题是，当前所有玩家实际上都在按照您的期望进行操作.他们如何弄清楚如何开始播放缓冲了一些内容，并测量了下载整个视频需要多长时间以及播放已经缓冲的内容需要多长时间.当视频不是以恒定速率下降时，就会出现问题.由于某种原因，播放器通常会比其他部分更快地获得视频的前几秒钟，因此播放器会认为它会比实际获得更快的速度.

The problem with that is all the current players actually do what you expected. How they figure out how to start playing is buffer some of the content and measure how long it takes to download the entire video vs how long it takes to play what is already buffered. The problem comes in when the video isn''t coming down at a constant rate. For some reason, the player will usually get the first few seconds of the video faster than it gets the rest of it, so the player will think it''s going to get the rest much faster than it actually does.
