This example demonstrates how to use the AXI Video DMA with other video IPs to do video frame transfers.
This example does not work by itself. It needs two other Video IPs, one for writing video frames to the memory and one for reading video frames from the memory.
To see the debug print, you need a Uart16550 or uartlite in your system, and please set "-DDEBUG" in your compiler options. You need to rebuild your software executable.

Main function.
This function is the main entry point of the example on DMA core. It sets up DMA engine to be ready to receive and send frames, and start the transfers. It waits for the transfer of the specified number of frame sets, and check for transfer errors.
