Interface/library to replace V4L2

Hi All,

I am hoping to develop interface between camera driver and video captured application. I am using ov8850 camera for TI board which supports csi2 interface. It uses a mipi-csi2 4-data-lane interface. The exisiting architecture csi2 connected to ISP for image processing and it connect with V4L2 .Since V4L2 is the current standard for interfacing with video devices in Linux. Video capture application can be interact with captured image using V4L2 API.

Now, I would like to create new interface/library between ISP and application. Basically I would like to replace V4L2 with some library called libcsi2 like libusb to control to/from the device.

Please suggest me whether do we have any kernel-mode or user mode driver needed. Please share your inputs on my design. Do we have any existing library does the same?

Thanks
