Cloud-Based Video Talk

Last Updated on : 2022-02-17 06:56:59download

Cloud-based video talk is implemented to connect an app with a cloud-based video intercom that supports video surveillance, access control, and more capabilities. This module relies on Tuya Smart Life IPC SDK and enables multiple features, such as video query, voice talk, and remote unlocking.

Feature overview

Integrate video surveillance

Use the cloud-based video surveillance management class to load configurations. After a successful callback, initialize a Powered by Tuya (PBT) IP camera (IPC) and connect to the video streaming channels to enable video previewing.

Integrate access control

Preview videos:

Similar to the process of video surveillance, use the cloud-based video surveillance management class to load configurations. After a successful callback, initialize a PBT IPC and connect to the video streaming channels to enable video previewing.
Accept video calls:
1. Register a device communication listener.
2. When the device receives a request, the listener triggers a callback. The communication type and data included in the callback indicate information about the device, and device configurations are loaded. After a successful callback, connect to the video streaming channels of the PBT IPC and enable video previewing.
3. With video previewing enabled, connect to the audio channels to enable voice talk.

Integrate the IPC SDK

The IPC SDK must be integrated. The following IPC SDK version is recommended:

implementation 'com.tuya.smart:tuyasmart-ipcsdk:3.27.5'

Cloud-based video talk management class

This class can be used to manage cloud-based video talk features. For example, load device configurations, register a device communication listener, query video surveillance device management, and query video access control devices.

Example

ITuyaCommunityVisualSpeak visualSpeak = TuyaCommunitySDK.getCommunityVisualSpeakInstance();

Load configurations

Loads device configurations. After the success callback, the subsequent process can continue and the audio and video communication between the app and the device can be started.

API description

void loadConfig(@NonNull String deviceId, @Nullable String gatewayId, ITuyaCommunityCallback callback);

Request parameter

Parameter	Description
deviceId	The device ID, required.
gatewayId	The ID of a gateway to which the device is connected. Otherwise, set the value to `null`.
callback	The callback.

Example

if (visualSpeak != null) {
    visualSpeak.loadConfig(deviceId, null, new ITuyaCommunityCallback() {
        @Override
        public void onFailure(String s, String s1) {
            L.e(TAG, "[loadConfig] onFailure:" + s1);
        }

        @Override
        public void onSuccess() {
            L.d(TAG, "[loadConfig] onSuccess");
            Intent intent = new Intent(VisualSpeakMainActivity.this, VisualSpeakVideoActivity.class);
            startActivity(intent);
        }
    });
}

Register a device communication listener

Registers a device communication listener. When the device sends a request to the app, the listener triggers a callback to indicate events. For example, the device calls the app, or the device hangs up the call.

API description

// Registers a listener.
void registerVisualSpeakCommunicationListener(IOnVisualSpeakDeviceCommunicationListener listener);

// Removes a listener.
void unRegisterVisualSpeakCommunicationListener(IOnVisualSpeakDeviceCommunicationListener listener);

Example

visualSpeak.registerVisualSpeakCommunicationListener(new IOnVisualSpeakDeviceCommunicationListener() {
    @Override
    public void receiveDeviceMessage(TYVisualSpeakCommunicationType tyVisualSpeakCommunicationType, TYDeviceMsgDataBean tyDeviceMsgDataBean) {
        switch (tyVisualSpeakCommunicationType) {
            case DEVICE_CALLING:
                break;
            case DEVICE_CALL_OTHER_APP_ANSWER:
                break;
            case DEVICE_CALL_CANCEL:
                break;
            case DEVICE_CALL_TIMEOUT:
                break;
            case DEVICE_CALL_HANGUP:
                break;
            case TALKING_TIMEOUT:
                break;
            case UNKNOWN:
            default:
                break;
        }
    }
});
