| .. zephyr:code-sample:: video-capture |
| :name: Video capture |
| :relevant-api: video_interface |
| |
| Use the video API to retrieve video frames from a capture device. |
| |
| Description |
| *********** |
| |
| This sample application uses the :ref:`Video API <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. |
| |
| Building and Running |
| ******************** |
| |
| For :ref:`mimxrt1064_evk`, build this sample application with the following commands: |
