Hi,
I have a Logitech USB camera connected on my board.
I have also enabled the CONFIG variables for V4L2 by menuconfig.
When I do fd = open("/dev/video0", O_RDWR) it fails saying that no
such file
or directory.
Then through shell I checked for the file /dev/video0 but it wasn't
present
there.
When I connect camera I can see the serial message for camera is
connected and its details.
I want to know when I connect the USB Camera who creates the /dev/
video0 file?
Do I need to create it in init.rc file? I believe V4L2 framework
should do it?
How does the V4L2 will be invoked when USB camera is connected who
initializes it?
If I want to get the preview frames from V4L2 is the /dev/video0
right
file?
I get the following message on Serial port:-
usb 2-1.2: USB disconnect, address 5
usb 2-1.5: new full speed USB device using tegra-ehci and address 6
usb 2-1.5: New USB device found, idVendor=046d, idProduct=08af
usb 2-1.5: New USB device strings: Mfr=0, Product=0, SerialNumber=0
usb 2-1.5: configuration #1 chosen from 1 choice
Quick help will be appreciated.
Thanks in advance.
Sachin Nikam.
