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).

Wiring

On NXP 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.
