This article introduces a small open-source project: AAC format analyzer. The full name of AAC is Advanced Audio Coding, which is a widely used Audio encoding format on the Internet and the best Audio encoding format at present. A large part of existing videos on the Internet use AAC for audio encoding. Developed Using MFC of VC 2010. Faad2, an open source decode
This article introduces a small open-source project: TS Encapsulation Format analyzer. TS stands for MPEG 2 Transport Stream (MPEG2 transmission Stream), which is widely used in broadcast and television systems, such as digital TVs and IPTV. My project is not large and can be used to learn the TS Encapsulation Format Structure. In addition, it supports separating video streams and audio streams in TS. And t

Before introducing how to perform lexical analysis, let's talk about a problem that is not very mentioned-how to read the sequence stream from the source file. Why is this issue
Recently, I wanted to be able to write a generic Code analysis tool (in fact the word is a bit too.) In fact the C code). See these days I see Code dizzy, despite the source insight help, still not enough wisdom to think a lot of places.The following are some of the main problems that are encountered today:1. Very many
PMD is an open source Code analyzer. You can find common programming flaws, such as unused variables, empty catch blocks, unnecessary object creation, and so on. Supports Java, JavaScript, Plsql, Apache Velocity, XML, XSL.In addition to this, PMD also includes CPD (copy, pas

Now we start to build a source code search engine that supports these requirements

The queryparser class is used to parse the query expression entered by the user, and the indexsearcher class searches for
