Description: Linux 操作系统提供进程间通信（IPC）机制，用来保证正在执行的进程在内核的协调下能够 共享资源、同步以及交换数据等。Linux 支持大量进程间通信机制，包括信号、等待队列、管道 以及Unix 系统V 中提供的进程间通信机制，如消息队列、信号量和共享内存。-Linux operating system to provide inter-process communication (IPC) mechanism used to ensure that the process is being implemented in coordination with the core to share resources, synchronization and exchange information. Linux support a large number of inter-process communication mechanisms, including signal and wait for the queue, pipeline and the Unix System V to provide inter-process communication mechanisms, such as message queue, the signal volume and shared memory.

Linux device driver must be solved in question is DuoGe process on the concurrent access to Shared resources, concurrent access will lead to a race condition. Linux provides DuoZhong solve a race condition the question way, the way of the scene suitable for different applications. Section 7.1 describes the concurrent and the concept of a race condition happened and occasion. 7.2 ~ 7.5 respectively explained interrupt shielding, atomic operation, spin lock and the signal of the concurrent control mechanism. Section 7.6 explain the concurrent control of globalmem increase after the device driver. Platform: |

Description: 1:此示例只是用来显示视频流,并没有处理存储视频及回放视频功能.
2:在打开项目后务必将构建里面的影子构建(Shadow build)取消.
3:实时显示视频,视频响应速度比VLC,QTAV等播放器快很多倍.
4:精简代码,在windows下是可以完整编译通过并运行的.linux下要将对应ffmpeg库文件替换.
5:支持三通道同步显示一个视频流，可以单击截图按钮截图放在最后一个通道.
6: 支持单个通道双击最大化显示.
7:代码处理并不够完整,还有很多需要优化的地方.
8:代码注释不够详尽,但是简单易懂.
9:没有使用定时器,采用信号槽机制实现视频流播放.
10:处理全部放在QFFmpge类中,包括注释也才到100行代码左右.
