and this my succeed command....
root@OpenWrt:/# mjpg_streamer -i "/usr/local/lib/input_uvc.so -y -d /dev/video0
-f 10 -r 320x240" -o "/usr/local/lib/output_http.so -p 8080 -w /www/webcam"
above i can stream at only 5frame per sec
i decrease quality of image and then i can stream at 10fream per sec
mjpg_streamer -i "/usr/local/lib/input_uvc.so -y -d /dev/video0 -q 50 -f 10 -r 320x240" -o "/usr/local/lib/output_http.so -p 8080 -w /www/webcam"
but the last perferman banwidth of webcam can only stream average at 7-8fps
if you want run on background mode. there are parameter like this
mjpg_streamer
-i | input " [parameters]"
-o | output " [parameters]"
[-h | help ]........: display this help
[-v | version ].....: display version information
[-b | background]...: fork to the background, daemon mode
Note: If you start mjpg-streamer in the background use this to stop it:
kill -9 `pidof mjpg_streamer`
Next step
boot at start
