$ git clone https://github.com/jacksonliam/mjpg-streamer.git
$ cd mjpg-streamer/
$ cd mjpg-streamer-experimental
$ make
$ make install
Flags
Input Flags
When specifying the input .so, use the following flags:
The -d flag is used to specify the device - for example, /dev/video0.
The -n flag is useful for suppressing error messages about pan/tilt controls, which most cameras don't have anyway.
The -y flag is used to specify YUYV format, in case the camera does not support mjpeg format.
The -r flag specifies the resolution, or whatever.
The -f flag specifies the frame rate.
