20190229推流中断问题--javacv的分析

目录

第一，javacv基础知识：

 1.基础：

1、图像像素格式与图片封装格式

2、图像？视频帧？傻傻分不清楚

3、编码？封装？傻傻分不清楚

4、音/视频源

5、流媒体协议

6、流媒体服务

比如常见的srs（开源的rtmp流媒体服务，当然它支持rtmp/hls/http-flv的分发）和nginx（通过安装模块可以支持rtmp，hls，http-flv分发），除此之外的收费的和一些不太友好的开源流媒体服务就不一一介绍了。

第二：javaCV入门指南：调用FFmpeg原生API和JavaCV是如何封装了FFmpeg的音视频操作？（个人更感兴趣javacv的）

参考大神链接：https://blog.youkuaiyun.com/eguid_1/article/details/83663035 

1、什么是JavaCPP

2.javaCPP直接调用FFmpeg的API

3、JavaCV是如何封装了FFmpeg的音视频操作？

1、帧抓取器（FrameGrabber）

2、帧录制器/推流器（FrameRecorder）

3、帧（Frame）
