Qt开发的本地摄像头功能，主要用来学习opencv摄像头以及ffmpeg编解码-Qt development of the local camera function, mainly used for learning opencv cameras and ffmpeg decoding

该源代码是基于ffmpeg编解码库的解码程序，可以实现解码一段视频，整个程序的开发环境是arm平台-The source code is based on ffmpeg codec library decoding procedures can be achieved decoding a video, the entire program development environment is arm platform

基于netty 开发 rtmp 推拉流服务器代码，可用ffmpeg代码测试(RTMP push-pull stream server code is developed based on netty, which can be tested by ffmpeg code)
