video_call

# IoT SDK: Video Call Example

Joins a VideoSDK meeting and streams video only. It sends the on-board camera as
hardware JPEG, and on the Korvo-2 it also draws the remote video on the LCD. The
session runs with `videoCodec = VIDEO_CODEC_JPEG`.

| Feature | XIAO ESP32-S3 (Sense) | ESP32-S3-Korvo-2 v3.0 |
|---------|:---:|:---:|
| Send video | ✅ | ✅ |
| Receive video | ❌ | ✅ |

On the XIAO (no display) `startSubscribeVideo()` returns `DEVICE_NOT_SUPPORTED`.

## Create the project

```bash
idf.py create-project-from-example "videosdk/iot-sdk=0.3.0:video_call"
```

(This example pulls the published component pinned in `main/idf_component.yml`:
`videosdk/iot-sdk: "^0.3.0"`.)

## Configure

```bash
idf.py set-target esp32s3
idf.py menuconfig
```

- SET Microcontroller > Audio hardware board: pick `ESP32-S3-Korvo-2` or `ESP32-S3-XIAO`. The default board is `ESP32-S3-XIAO`.
- VideoSDK Configuration: set Auth token (JWT) and Meeting / room ID.
- Example Connection Configuration: Wi-Fi SSID and password.

The token and meeting ID live in `sdkconfig`, not in source. Don't hardcode a
real token and don't commit one.

## Build & flash

```bash
idf.py build
idf.py -p <PORT> flash monitor
```
