  mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
-----------------------------------------------------------------------
Example #2:

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"
