This application demonstrates simple loop back from capture to display. Application takes input through TVP7002 decoder on VPSS VIP port. Capture buffers are displayed using V4L2 display driver. Sample application uses user pointer buffer mechanism for both capture and display driver. User pointer buffers are taken from FBDEV driver. V4L2 capture driver outputs YUV422 (y and cbcr interleaved) data to memory and display driver displays the same format from memory. Capture driver detects the incoming resolution, configures capture and display driver for same resolution. For e.g. For 1080P60 input resolution, Application sets the buffer size to 1920*1080*2 for both display and capture. Application changes the display resolution to 1080P60 on display using the sysfs entry
