最近开发项目需要使用JWplayer插件播放视频,但是无论换那个版本.换什么样的视频总是提示Error loading media: File could not be played错误,废了好大的劲终于解决了,开始以为是视频编码的事,最后无意间发现是iis不支持.mp4格式播放的问题. 解决办法: IIS默认配置没有添加MP4文件,导致打开MP4文件会404. 打开IIS管理器,MIME类型 添加,扩展名为mp4,类型为video/mp4 点击确定. 问题解决了,测试地址:http://118…

传送门:http://codeforces.com/contest/976/problem/E 参考:https://www.cnblogs.com/void-f/p/8978658.html 题意: 对于每一个生物,有一个ph值和伤害值.现在有a次使ph值乘2的机会,有b次是伤害值等于ph值得机会. 问最后能得到最大的伤害总和是多少. 思路:自己一开始也想的是贪心,但是贪的姿势不正确.明确,a次一定是给同一个生物放大的.但是至于是对哪一个生物放大,还是要用暴力一个一个去找,而不要对排序后第一个…

题目分析: 由于乘二的收获很大,所以我们可以证明乘的数一定是同一个,接着排序后依次选取,判断一下即可. 题目代码: #include<bits/stdc++.h> using namespace std; ; int n,a,b; struct node{ int hp,dm; }d[maxn]; int cmp(node alpha,node beta){ return alpha.hp-alpha.dm > beta.hp-beta.dm; } void read(){ scanf(…

音视频的发展史 早期:<embed>+<object>+文件 问题:不是所有浏览器都支持,而且embed不是标准. 现状:Realplay.window media.Quick Time .Flash 问题:每个厂商每个标准,网站编码和格式也都不相同,flash的出现解决了面的问题,但是apple在07年决定任何设备将不再支持flash.而安卓也在4.0版本之后不再支持Flash, 因为Flash很占内存. HTML5认为浏览器应该原生支持音视频,因为他们现在也是web中的一等公民…

前言 html5中对音频,视频播放原生支持.最近做了一个音乐播放器,得益于快过年了,才能抽出一点时间来总结一下.总的来说,html5对audio的支持非常强大, 难怪flash要死.浏览器上装播放插件的时代已经接近尾声了.目前大多数浏览器都支持了大部分常用的api,ie8及其以前除外(万恶的ie啊). HTML5 音频虽然很健壮,但有其局限性,这主要取决于它的实现.对于音乐播放器(点唱机播放器)或简单的声音效果,它很有效,但是对于声音密集的应用程序如游戏,它的表现不是很理想.所以有了Web Au…

导读 正则表达式是什么?有什么用? 正则表达式(Regular Expression)是一种文本规则,可以用来校验.查找.替换与规则匹配的文本. 又爱又恨的正则 正则表达式是一个强大的文本匹配工具,但是它的规则实在很繁琐,而且理解起来也颇为蛋疼,容易让人望而生畏. 如何学习正则 刚接触正则时,我看了一堆正则的语义说明,但是仍然不明所以.后来,我多接触一些正则的应用实例,渐渐有了感觉,再结合语义说明,终有领悟.我觉得正则表达式和武侠修练武功差不多,应该先练招式,再练心法.如果一开始就直接看正则的规…
