Are there any examples of using Cohn to control GoPro13？

[Duanener]

I have tested the feasibility of demos/python/tutorial/tutorial_modules/tutorial_9_cohn/communicate_via_cohn.py with GoPro13, is there any examples to guide me to further control the shooting and transmit the video at the same time?

When I run this code

async def main(ip_address: str, username: str, password: str, certificate: Path) -> None:
    url = f"https://{ip_address}" + "/gopro/camera/state"
    logger.debug(f"Sending:  {url}")

    token = b64encode(f"{username}:{password}".encode("utf-8")).decode("ascii")
    response = requests.get(
        url,
        timeout=10,
        headers={"Authorization": f"Basic {token}"},
        verify=str(certificate),
    )
    # Check for errors (if an error is found, an exception will be raised)
    response.raise_for_status()
    logger.info("Command sent successfully")
    # Log response as json
    logger.info(f"Response: {json.dumps(response.json(), indent=4)}")

    # preview
    url = f"http://{ip_address}/gopro/camera/stream/start"
    logger.debug(f"Sending:  {url}")

    querystring = {"port": "8556"}
    response = requests.request("GET", url, params=querystring, headers={"Authorization": f"Basic {token}"}, verify=str(certificate))

    print(response.text)



if __name__ == "__main__":
    parser = argparse.ArgumentParser(description="Demonstrate HTTPS communication via COHN.")
    parser.add_argument("ip_address", type=str, help="IP Address of camera on the home network")
    parser.add_argument("username", type=str, help="COHN username")
    parser.add_argument("password", type=str, help="COHN password")
    parser.add_argument("certificate", type=Path, help="Path to read COHN cert from.", default=Path("cohn.crt"))
    args = parser.parse_args()

    try:
        asyncio.run(main(args.ip_address, args.username, args.password, args.certificate))
    except Exception as e:  # pylint: disable=broad-exception-caught
        print(e)
        logger.error(e)
        sys.exit(-1)
    else:
        sys.exit(0)

I get output:
