-----------------------------------------------------------------------
Example #1:
 To open an UVC webcam "/dev/video1" and stream it via HTTP:
  mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
-----------------------------------------------------------------------
Example #2:
 To open an UVC webcam and stream via HTTP port 8090:
  mjpg_streamer -i "input_uvc.so" -o "output_http.so -p 8090"
-----------------------------------------------------------------------
Example #3:
 To get help for a certain input plugin:
  mjpg_streamer -i "input_uvc.so --help"
-----------------------------------------------------------------------
In case the modules (=plugins) can not be found:
 * Set the default search path for the modules with:
   export LD_LIBRARY_PATH=/path/to/plugins,
 * or put the plugins into the "/lib/" or "/usr/lib" folder,
 * or instead of just providing the plugin file name, use a complete
   path and filename:
   mjpg_streamer -i "/path/to/modules/input_uvc.so"
-----------------------------------------------------------------------
```

```bash
root@edison:~# mjpg_streamer -i "input_uvc.so -d /dev/video0" -o "output_http.so"
mjpg_streamer -i "input_uvc.so -f "15" -r "640x480" -w "./www"
