* 录屏功能支持:开始,暂停,结束。
* 使用Qt+C++封装FFmpeg API,没有使用废弃的FFmpeg API。
* 主线程:Qt GUI线程,以后可接入录屏UI。
* 父线程(读):ScreenRecordThreadProc() 打开输入/输出流,创建子线程,然后从fifoBuffer读取帧,编码生成各种格式视频。
* 子线程(写):ScreenAcquireThreadProc() 从输入流采集帧,缩放后写入fifoBuffer。
* 父子线程通过AVFifoBuffer(环形缓冲区)通信。是生存者与消费者的关系。使用条件信号和互斥量提高CPU利用率。
* 目前没添加录音功能,纯视频。
