javascript-php do video website server very card what to do??

Environment:
php5.3.9
Apache 22
mysql5.6.x
Windows

Several problems encountered when using the video website (Local environment test):

A. 几十个视频。通过 canvas 截取视频第一帧做封面。

    Video Source list var vsrclist = [Src1, Src2, src3 ....]; Queue mode intercepts the first frame of the video (if it is not taken in a queue, basically all will intercept the failure ....        )///Even if the first frame of the video is taken in a queue, there is a high chance that the video first frame intercept will fail//Open the console network, a large number of requests show pending ... var dequeue = function () {        var CurItem = Vsrclist.shift ();                        if (CurItem) {//This side is added to the node on the page:        Dequeue ();        }    };           Dequeue ();        Get video first frame function getvshowpic (src, FN, opt) {var v = document.createelement (' video ');        var cav = document.createelement (' canvas ');        var ctx = Cav.getcontext (' 2d ');        V.currenttime = 1; V.addeventlistener (' Canplay ', function () {if (opt = = = = undefined) {opt = {W            : V.videowidth, H:v.videoheight};            } ctx.drawimage (this, 0, 0, opt[' W '), opt[' H ']);            var src = cav.todataurl (' image/jpeg ', 1);        FN (SRC);        }, False); V. src = src; }

B. 由于第一个问题中已经出现十分卡顿的现象。视频播放的时候就更加夸张的突出了。主视频一直显示加载中，相关视频列表封面全部截取失败

问题1：是否php就不适合做视频网站？？
问题2：像优酷，爱奇艺之类的视频网站运行如此顺畅的原因是什么？
问题3:类似于优酷，他们的视频封面是手动上传的还是自动截取视频第一帧做的封面？？，因为若是单纯的播放一个视频的话，倒是不会出现卡顿的现象，我只要把自动截取视频第一帧的代码给拿掉，就不会出现任何卡顿...

1. The focus of the video site is the CDN cache and bandwidth of the video, and what language does it matter

2. Others use a CDN Ah, looked at you should be nothing more than a exercise, how and others than

3. Read your description, speculate that your so-called cover is read from the video every time, that is not the card is strange, a mature video site system after the video upload will be offline video processing, including not limited to the following work (indefinite):

   • Standardized video formats (sometimes non-standard formats do not enable video caching on the browser side)

   • Compression into multiple quality video formats (e.g. low-medium-high, or 240p, 360p, 480p, 720p, 1080p, etc.)

   • Capture some frames as a preview (you can intercept n and then manually intervene)

   • Add watermark (optional)

   • Upload to CDN

Video sites have a large bandwidth requirement. is not a server configuration. Live broadcast to server requirements high!

You're doing this.
is running in local JS.
No, it's weird.
