9This sample application uses the Video API to retrieve video frames from the
10video capture device, writes a frame count message to the console, and then
11discards the video frame data.

13Requirements
14************
15
16This sample requires a video capture device (e.g. a camera).

21Wiring
22******
23
24On :ref:`mimxrt1064_evk`, The MT9M114 camera module should be plugged in the
25J35 camera connector. A USB cable should be connected from a host to the micro
26USB debug connector (J41) in order to get console output via the freelink
27interface.
