capture_stream

# Capture Stream Example

This example demonstrates the following:

- How to initialize esp_video with specific parameters
- How to open video device and capture data stream from this device

## How to use example

### Hardware Required

* A ESP32-P4 development board with MIPI-CSI interface
* A SC2336 camera sensor
* A USB Type-C cable for power supply and programming

### Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

```
idf.py -p PORT flash monitor
```

(To exit the serial monitor, type ``Ctrl-]``.)

See the [ESP-IDF Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32p4/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.

## Example Output

Running this example, you will see the following log output on the serial monitor:
