Lex是美国Bell实验室用C语言研制的一个词法分析程序自生成工具。它的基本原理就是使用正则表达式扫描匹配文本，并为每一个匹配模式定义一些操作，当用C语言作宿主语言时，这些操作都由C语言实现。一种匹配的正则表达式可能会包含相关的动作。这一动作可能还包括返回一个标记。当 Lex 接收到文件或文本形式的输入时，它试图将文本与正则表达式进行匹配。它一次读入一个输入字符，直到找到一个匹配的模式。如果能够找到一个匹配的模式，Lex 就执行相关的动作（可能包括返回一个标记）。-Lex Bell Laboratories of the United States with C language developed by a lexical analysis tool generated from the process. Its fundamental principle is to use a regular expression matching text scanning, and for every definition of a matching model for operation, when the C language of the host language, these operators by C language. A match of which is likely to contain expressions related to the moves. This action may also include the return of a marker. When Lex reception of the document or text input, it is trying to text and is a regular expression matching. It read an input into the characters, until they found a matching pattern. If they can find a matching model, Lex on the implementation of the action (which may include a return of markings). 下载

1、简介 此代码是IS0 13818-5 MPEG2系统层协议分析代码，经过我的一点修改，现在终于可以在VC++ 6.0下编译运行, 发布上来献给那些为了理解MPEG2系统层协议而苦苦加班的程序员。为了可以在windows下编译，我修改了部分操作系统相关代码，注解掉了一些main函数，只留下decode.cpp中的main函数没有注解，所以编译后的程序是TS流系统层解码分析程序，如果要实现其他功能如encode，只要把decode.cpp中的main函数注解，把encode.cpp中的main函数注解去掉即可。 2、VC++6.0编译设置 需要在菜单Poject-〉Settings 弹出的对话框中把预编译头设置成Not using precompiled headers,如Vc_setting.jpg中的图片所示。 3、运行 编译生成decode2.exe文件后在命令行如下运行 decode2.exe d:\cctv.ts 一开始在没有分析完PAT和PMT表时会打印一些如unexpected pid: 513的消息，请耐心等待一会儿就会发现分析的系统层信息打印了。可能刷屏很快导致你看不清信息，可以将打印信息重定向到某个文件中，如下： decode2.exe d:\cctv.ts >c:\ts_decode.txt 运行decode2.exe的同时会在当前目录生成过滤后的PES文件，文件名格式stream512，512为PID。 -a brief account of this code is ISO 13818-5 MPEG2 system layer protocol analysis code, After I few modifications, now he can finally in VC 6.0 compiler operation, Published line with those dedicated to understanding MPEG2 system layer protocol and an overtime programmers. To be compiled under the windows, I revised the relevant part of the operating system code, Notes swap some of the main function, leaving only the main decode.cpp function without notes, So when a compiled program is TS system layer decoding process analysis, if we are to achieve other functions such as encode. decode.cpp as long as the main function of the rich encode.cpp put the main function annotation will be removed. 2.
