DMVA2IPNC-MT5 resolution problem

Hi,

I am trying to increase the resolution of DMVA2IPNC-MT5 beyond 2MP (as it has a 5MP sensor). My first achievement was to make it work with 3MP (MJPEG) by increasing the memory to CMEM and decreasing the kernel memory. I, then, managed to get a resolution of around 4MP MJPEG (2048x1944) by doing the following:

1. decreasing the kernel memory to 26M and allocating the rest to CMEM.

2. I noticed that using the existing 5MP use-case in avServerUi.c ends up with a buffer allocation error. So I used the same use-case as AVSERVER_UI_CAPTURE_MODE_3_MEGA (in /IPNetCam/ipnc/av_capture/application/ipnc/av_server/src/common/avServerUi.c) but just changed the capture width and height to 2048 and 1944 (max. y-resolution). 

I, then, decided to go beyond this resolution to achieve 5MP resolution. But the problem is that if I want to increase the width more than 2048, I get an image similar to a vertical bar with maximum y-resolution (1944) and very small width (96). 

Can anyone please suggest me what else needs to be changed to increase the image width beyond 2048?
