We want to get some reference code to change camera image resolution using VIC(VIDEO IMAGE COMPOSITOR)

Now I am using the max9286 to capture multiple cameras.One max9286 can connect four 720P cameras,but the max9286 outputing image resolution is 5120720.From the datasheet of TX1,I know that VIC(VIDEO IMAGE COMPOSITOR) can change the resolution from 5120720 to 25601440.The 25601440 image will not exceed the maximum encoding width(4096). My main concern is how to get the similar code and save my developping time!

We are implementing the sample code now. Will public to you after finished.

Thank you !
