Here I will simply talk about Linux install Linux camera driver. In the new Linux kernel there is a majority of USB camera drivers. So you can choose to

This article explains how to configure the Linux kernel to implement its support for USB cameras. 1, configure the kernel; Allow the following command to configure the Linux kernel [HTML] view plain copy print?
