Video Capture
#############
Description
***********
This sample application uses the Video API to retrieve video frames from the
video capture device, writes a frame count message to the console, and then
discards the video frame data.
Requirements
************
This sample requires a video capture device (e.g. a camera).
- :ref:`mimxrt1064_evk`
- `MT9M114 camera module`_
Wiring
******
On :ref:`mimxrt1064_evk`, The MT9M114 camera module should be plugged in the
J35 camera connector. A USB cable should be connected from a host to the micro
USB debug connector (J41) in order to get console output via the freelink
interface.
