mjpg-streamer简单解析

胧霖 于 2017-11-15 08:52:11 发布 6196 收藏 20

mjpg-streamer的实现也相对比较简单:
##主函数
在main函数里面首先当然是实现命令输入解析,对一些信号的处理,主要是SIG_PIPE和SIG_INT:

忽略掉SIG_PIPE信号,做Linux通信的一般都这么做,否则当出现Pipe broken时,程序会自动退出。
然后就是为SIG_INT添加处理函数。

##数据采集
通过加载动态链接库后就可以获取到要进行操作的方法,这些方法是init、stop、run和cmd这四种。因为是为了摄像头数据传输,别的我也不管了。首先是输入,文件是input_uvc.c:
在初始化函数中init(),当然是对摄像头参数设置和初始化啦:

其中pglobal->buf为输出的buffer,也就是在后面需要传输的数据。
##数据传输
既然是为了远程视频传输,当然这里输出应该选择output_http.c,即网页传输。输出方法和输入方法一样,主要为init,stop,run和cmd四个函数组成,这里就主要讲输出传输的过程,主要是run函数中,创建了服务器thread:

其中server_thread()线程回调函数在httpd.c文件中,其中是一个TCP Server的初始化过程,并且设置的最多listen 10个client:
