		v4l2-tool 1.0.3
----------------------------------------------------
This application is used to get more hardware information from attached webcam device.
This application is tested with gspca and uvcvideo v4l2 kernel drivers.
There are five tabs each corresponding to one ioctl call and returning respective
structure fills with values.
1)Capability :-      This tab gives driver name, bus info, card info, driver version and various 
		     capabilities supported by webcam.
2)Crop Capability :- This tab gives supported width and height values.
3)Input :-           This tab gives video input and its type name.
4)Query Control :-   This tab gives query control information for all 3 BASE options.
5)Frame Formats :-   This tab gives various frame formats supported by webcam and default one 
		     set by kernel module.
6)device info :-     This gives information about requested webcam device like its vendor
		     name,kernel module name,usb id's,sound recording support and v4l standard.
		     Also this tab provides which usb standard webcam hardware is using and give
		     some information about that standard.
7)Suggest driver :-  This tab provides first lsusb output to know attached webcam device USB ID's.
		     Then enter those ID's below to know whether your webcam is already supported
		     by uvcvideo or gspca kernel module by clicking on Suggest driver tab. If 
		     your webcam is supported then you will get below kernel module name and URL
		     to download it.

ALL above information is of get type which is default set in kernel modules. There is no 
support for modifying webcam properties(no set functionality on webcam).

Assumptions
------------------------------------------------------
This tool works with webcam's that are using uvcvideo and gspca v4l2 kernel drivers.

Limitations
-----------------------------------------------------
Currently this application is working for v4l2 kernel drivers. I have similar v4l 
application also but after seeing a lot of development in v4l2, i decided
to release first v4l2-tool application under v4lx-devinfo project.

ToDo
-----------------------------------------------------
Trying to provide any other remaining information about webcam hardware.
Also trying to add video viewer support as part of v4lx-devinfo project.
