Summary of gdb The purpose of a debugger such as gdb is to allow you to see what is going on “inside” another program while it executes—or what another program was doing at the moment it crashed. gdb can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: • Start your program, specifying anything that might affect its behavior. • Make your program stop on specified conditions. • Examine what has happened, when your program has stopped. • Change things in your program, so you can experiment with correcting the effects of one bug and go on to learn about another. You can use gdb to debug programs written in C and C++.

在使用计算器时 增加发音功能

说明：  使用ffmpeg做的播放器。SDL处理音频，ffmpeg处理编解码音视频文件，qt做ui界面。使用多线程双缓冲队列播放音视频。使用视频追逐音频的策略实现音视频同步。支持视频镜像操作，黑白彩色转换。(A player made of ffmpeg. SDL processes audio, ffmpeg processes codec audio and video files, QT is the UI interface. Use multi-threaded double buffer queue to play audio and video. The strategy of video chasing audio is used to realize audio and video synchronization. Support video image operation, black and white color conversion.)
