Video Capture
4+
#############
5+
6+
Description
7+
***********
8+
9+
This sample application uses the Video API to retrieve video frames from the
10+
video capture device, writes a frame count message to the console, and then
11+
discards the video frame data, and the captured image will be shown on the display
12+
13+
Requirements
14+
************
15+
16+
This sample requires a video capture device (e.g. a camera).
17+
18+
- :ref:`hpm6800evk`
19+
- `ov5640 camera(mipi csi) module`_
20+
- `ov7725 camera(dvp) module`_
21+
22+
Wiring
23+
******
24+
25+
On :ref:`hpm6800evk`, if use DVP, the ov7725 camera module should be plugged in the
26+
J12 camera connector; if use MIPI CSI, the ov5640 camera module should be plugged in the Expansion Board J6 camera connector
27+
28+
Building and Running
29+
********************
30+
31+
For :ref:`hpm6800evk`, build this sample application with the following commands:
32+
33+
.. US DVP camera:
34+
.. zephyr-app-commands:: west build -p always -b hpm6800evk -S video_dvp samples/subsys/video/capture/
35+
36+
.. US MIPI CSI camera:
37+
.. zephyr-app-commands:: west build -p always -b hpm6800evk -S video_mipi samples/subsys/video/capture/
38+
39+
