RTSP流和USB摄像头转MJPEG使用VLC

测试环境：

       系统： Ubuntu14.04 LTS Desktop

       设备：海康IP摄像头和USB摄像头

1、需要先安装vlc包，命令行运行

sudo apt-get update
sudo apt-get install vlc

2、安装完成后，使用cvlc工具，在命令行运行（注：测试环境的海康摄像头IP 10.0.10.64  ，  rtsp的端口 554 ，   关闭了http basic 验证）

cvlc -R rtsp://10.0.10.64:554/Streaming/Channels/101 --sout "#transcode{vcodec=mjpg,vb=25,scale=1.0,fps=10,acodec=none}:standard{access=http{mime=multipart/x-mixed-replace; boundary=7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8888/videostream.cgi}"

运行返回

3、使用USB摄像头，在命令行运行（注：这里使用的USB摄像头系统设备名称为 video0）

cvlc --no-audio v4l2:///dev/video0 --v4l2-width 1920 --v4l2-height 1080 --v4l2-chroma h264 --v4l2-fps 30 --v4l2-hflip 1 --v4l2-vflip 1 --sout "#transcode{vcodec=mjpg,vb=25,scale=1.0,fps=10,acodec=none}:standard{access=http{mime=multipart/x-mixed-replace; boundary=7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8554/videostream.cgi}"

运行返回
