NVMM support on Jetson #224

Hi,

I was looking at your jetson implementation. As far as I can see there is no DMA capability. Current setup rtsp source > gstreamer > decode > image buffer > convert to png > ultimate alpr

You don't need to convert the image to png, our sdk accepts a buffer as input. Check the signature of the process function at https://www.doubango.org/SDKs/anpr/docs/cpp-api.html.
