 ## Detailed outline of example application
 
 This application opens a client to VDO and starts fetching frames (in a new thread) in the YUV format. It tries to find the smallest VDO stream resolution that fits the width and height required by the neural network. The thread fetching frames is written so that it always tries to provide a frame as new as possible even if not all previous frames have been processed by larod.
