最近小编在为大家录制视频展示文件的时候，需要花钱来购买，才能去除水印，而且额外的软件增大了电脑的负担。所以小编就想着自己打造一款录屏程序。
对于录屏的程序，小编想实现的目的就是实现屏幕的录制，并记录自己的声音。而我们的程序也是基于此进行实现的，程序的框架如下图所示：
主程序启动后，我们利用两个线程来分别实现音频的录制和视频的录制，再将两个线程录制的音频和视频通过主程序进行合成，最终形成我们的录屏结果。
这里需要注意的是，我们的音频和视频的录制必须是同时启动和结束。下面我们一起来看看程序吧～～
01.音频的录制
首先是音频的录制，我们利用pyaudio库来启用我们的麦克风，然后收录我们的声音，并将录音保存到本地的mp3文件当中，程序如下图所示：
上述的程序中，我们首先创建一个音频的输入流对象stream，不断的获取音频数据，然后我们利用wave库，不断的读取输入流中的音频数据，写入到本地的音频当中。这里的self.recording是一个关键的参数，其控制着音频是否持续的记录。
02.视频的记录
接下来是对于视频的记录，对于视频的记录，我们采用的是不断的获取当前屏幕的图片截屏，然后利用opencv写入到视频文件当中去。程序如下图所示：
上述的程序中，我们通过不断的捕获当前屏幕的内容，然后通过opencv的视频写入对象，将图片不断的写入到视频文件当中去。注意这里用到了与音频录制相同的self.recording参数，来控制视频是否继续进行记录。
上述的程序中，我们开启了两个线程来分别录制视频和音频，同时让主程序保持循环等待，当我们输入“quit”时，让两个子线程同时结束。
注意，这里会有几毫秒的时间差，但是不影响，然后我们把两个子线程采集到的音频和视频进行合并，便完成了我们的录频程序。
而且34秒的视频，只要 1.26M空间，非常小巧方便！
最后视频看一下效果
小编有话说：
这篇文章我们会录制视频，我们的里面有360个趣味案例，但是有一些案例对初学者来说还是有点难度的。即使你拿到源码，运行也会报错，毕竟开发的环境，路径，依赖库不一样！
通过视频讲解把源码一行一行的细细解读给大家，方便大家理解和学习，到时源码和视频都放在B站上！大家敬请期待哦，尝鲜的可以直接点击阅读原文！
