Camera, Fswebcam Installation

Small and simple webcam for *nix

root@Minnowboard:~# apt-get install fswebcam

Camera, Kernel Drivers Tests

Are the Camera drivers being installed correctly?

This output shows that Camera is recognized by the Kernel but the input/inputX device is not set:

user@Minnowboard:~$ dmesg

This output shows that Camera is recognized by the Kernel and the input/inputX device is set:

If your camera is recognized and the input/inputX device is set then go to "Camera, Kernel Modules Tests" section, otherwise keep reading

Camera, Kernel Drivers Enablement

Compile your Kernel, once compiled let's enable all the required drivers for our Camera:

user@Minnowboard:~$ cd linux
user@Minnowboard:~$ make menuconfig

Device Drivers  --->
 <*> Multimedia support  --->

Symbol: MEDIA_CAMERA_SUPPORT [=y]
[*]   Cameras/video grabbers support
Symbol: MEDIA_USB_SUPPORT [=y]
[*]   Media USB Adapters  --->

Device Drivers  --->
 <*> Multimedia support  ---> 
   [*]   Media USB Adapters  ---> 

Symbol: USB_VIDEO_CLASS [=m]
<M>   USB Video Class (UVC)
Symbol: USB_VIDEO_CLASS_INPUT_EVDEV [=y]
[*]     UVC input events device support

For FaceCam 320X the "required" controller (seems it uses another driver) is GSPCA_PAC7302, we enable it as module

Device Drivers  --->
 <*> Multimedia support  ---> 
   [*]   Media USB Adapters  ---> 

Symbol: USB_GSPCA_PAC7302 [=n]
<M>   Pixart PAC7302 USB Camera Driver

Once configuration changes are done, we save, compile again, reboot and check if Camera is recognized and input/inputX device is set as described in "Camera, Kernel Drivers Tests" section

Camera, Kernel Modules Tests

Check some Camera Kernel modules that could be loaded

user@Minnowboard:~$ lsmod

uvcvideo               71309  0

Camera, Userspace Tests

We add our user as part of video group, look again that /dev/videoX is enabled and finally we get our picture with fswebcam application

root@Minnowboard:~# apt-get install fswebcam
root@Minnowboard:~# adduser <user> video
user@Minnowboard:~$ ls /dev/video*
/dev/video0
user@Minnowboard:~$ fswebcam -r 1280x1024 -s brightness=65% -s Contrast=50% -s Gamma=100% --jpeg 100 --no-banner image.jpg
