miniupnpc-1.2 test setting on ARM9

miniupnpc-1.2 installation on ARM9
=======================================================================
1. Link ARM9 lan wire to asus router and connect ASUS router to internet. the miniupnpc-1.2
had installed on ARM9 device.

ASUS Router setting default ip 192.168.1.1,router must enable upnp function first !!
































2. on ARM9 board

4.check router status, we can see the ports had been sucessfully opened !!

type 192.168.50.111:80 on other PC browser,then you can see ARM9 webcam
if we already running this service on it!!

mjpg_streamer or uvc_streamer always Unable to set format: Invalid argument

When running webcam AP like mjpg_streamer or uvc_streamer on your PC
(need to "depmod -a" , and "modprove uvcvideo" , this will install uvc driver on your PC)

many people will see this:
[arthur@localhost mjpg-streamer-r63]$ ./mjpg_streamer
MJPG Streamer Version.: 2.0
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480
i: Frames Per Second.: 5
i: Format............: MJPEG
Unable to set format: Invalid argument
Init v4L2 failed !! exit fatal
i: init_VideoIn failed

this can be easily bypass by using follow cammond:
/usr/local/bin/./mjpg_streamer -i "input_uvc.so -d /dev/video -y" -o "output_http.so"


This is because your PC is USB2.0 support, so the streamer can only use yuv mode to output your images,
it's 80 frames/sec, much more then MJPEG mode. if you really want test MJPEG mode,
then you can try

sudo rmmod echi_hcd,

this will force take off usb2.0 driver, and only usb1.1 driver running. and after this you can run your AP happily.

My system is fedora6 , /usr/src/kernels/2.6.22.14-72.fc6-i586/
