Tutorial: How to "live stream" a media file

I have tried a while to setup a free (open source etc.) live streaming solution which is able to stream “anything” to a flash frontend. The basic idea is to stream TV from v4l2 (and similar), but I also wanted to stream files (movies). I found that most tutorials only show how to setup the streaming or only show how to get a flash player up and running. The whole roundtrip is not really described and has its own difficulties. This tutorial describes the whole “roundtrip” from a media file on your disk to displaying it in a browser. I know that there are easier ways to send a media file to some player in a browser and I also know that playing a file is not really live streaming. (This is why I have put it in double quotes.) However, it shows the principle and it might be easier to set this up as a first step.

C语言编写简易病毒[通俗易懂]

本次实验设计的是一个基于C语言的恶意代码,其执行流程如下: 1、 在病毒第一次执行时,即检测到注册表的任务管理器没有被禁用,则病毒依次执行以下功能: 创建开机启动项,在系统目录路径下面复制文件,将其作为自启动路径; 禁用任务管理器; 禁用注册表编辑器; 联网获取图片并修改桌面背景(重启生效); 修改注册表屏蔽用户键盘输入为1(重启生效); 删除驱动器盘符,使桌面以及开始菜单快捷方式失效; 在桌面恶意增殖,生成名字随机的自身拷贝文件; 电脑强制关机; 2、计算机重新启动之后由于任务管理器已经被禁用,所以只在桌面恶意增殖,同时桌面背景更换并且键盘输入失效。 1.增殖模块 为了实现恶意代码的自我增殖,使用windows系统自带的API函数SHGetSpecialFolderPath,获取当前用户的桌面路径;使用GetModuleFileName函数,获取当前执行程序的路径,最后通过使用Copyfile函数,完成自我增殖。 增殖模块相关代码如图2.1所示。
