.. zephyr:code-sample:: video-capture-to-lvgl
:name: Video capture to LVGL
:relevant-api: video_interface
Capture video frames and display them on an LCD using LVGL.
Description
***********
The application uses the :ref:`Video API <video_api>` to retrieve video frames from
a video capture device, write a frame count message to the console, and then send
the frame to an LCD display.
Requirements
************
This sample requires a supported :ref:`video capture device <video_api>` (e.g., a camera)
and a :ref:`display <display_api>`.
Wiring
******
On the `WeAct Studio STM32H743`_, connect the OV2640 camera module and the 0.96" ST7735
TFT LCD display. Connect a USB cable from a host to the micro USB-C connector on the
board to receive console output messages.
