1. Network Monitoring Server description; How can I use a camera for a time-based monitoring system? That is to say, there is a dedicated network control server, and other clients use network image monitoring software or a browser to constantly monitor the camera's location and everything that happens. I have never used professional video surveillance, nor do I know what professional devices they use or what functions they have. I understand the following network monitoring server applications:

I have encountered a problem if I use OPENCV APIs, I cannot change the width and height ofWebcam output: the ); );But after seaching the internet, I had found the key point:The webcam on Linux usually uses the V4L API, and I has not install the library for v4l.When OpenCV was built, it does not includes the V4L API interface.So, that ' s the solution:1.install v4l Dev Library on Ubuntu:libv4l-dev2. Enter OpenCV sourcecode dir, and reinstall it

The example in this article will be implemented by reading the PC webcam video data and sending it as a live stream with the RTMP protocol. Example contains the1, the use of FFmpeg libavdevice2. The basic flow of video decoding, encoding and pushinghas a strong comprehensive.To use Libavdevice related functions, you first need to register the relevant componentsAvdevice_register_all ();Next we want to list the DShow devices available in the computerAv
