VideoSDK Class Native Android Methods - Flutter

You call these methods from your app's Android code. Import the class as live.videosdk.videosdk.VideoSDK.

getInstance()

• This method is used to get an instance of the VideoSDK class.

Returns

• VideoSDK instance

Example

Kotlin

import live.videosdk.videosdk.VideoSDK

val videoSDK = VideoSDK.getInstance()

Java

import live.videosdk.videosdk.VideoSDK;

VideoSDK videoSDK = VideoSDK.getInstance();

---

registerVideoProcessor()

• This method is used to register your custom video processor during app initialization. It takes a string representing the unique processor name along with an instance of your processor to complete the registration.
• Register it in your MainActivity. Then apply it from Dart with room.setVideoProcessor(), using the same name. A name that was never registered throws an error.
• Your processor implements VideoFrameProcessor from live.videosdk.rtc.android.listeners. Its onFrameCaptured() method receives each camera frame as a videosdk.org.webrtc.VideoFrame, and returns the frame to send: the same frame, or a new one.
• The SDK releases both the frame it passes in and the frame you return, so do not call release() on either.

Parameters

• videoProcessorName

  • type: String
  • required: true
  • The name of the processor whose effect you wish to apply.

• videoProcessor

  • type: VideoFrameProcessor
  • required: true
  • The instance of the processor whose effect you wish to apply.

Returns

• void

Example

Kotlin

MainActivity.kt

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import live.videosdk.rtc.android.listeners.VideoFrameProcessor
import live.videosdk.videosdk.VideoSDK
import videosdk.org.webrtc.VideoFrame

class CustomVideoProcessor : VideoFrameProcessor {
    override fun onFrameCaptured(videoFrame: VideoFrame): VideoFrame {
        // Apply your effect here, and return the frame to send.
        return videoFrame
    }
}

class MainActivity : FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        val customVideoProcessor = CustomVideoProcessor()
        val videoSDK = VideoSDK.getInstance()
        videoSDK.registerVideoProcessor("customVideoProcessorName", customVideoProcessor)
    }
}

Java

MainActivity.java

import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import live.videosdk.rtc.android.listeners.VideoFrameProcessor;
import live.videosdk.videosdk.VideoSDK;
import videosdk.org.webrtc.VideoFrame;

public class MainActivity extends FlutterActivity {
    @Override
    public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        super.configureFlutterEngine(flutterEngine);
        CustomVideoProcessor customVideoProcessor = new CustomVideoProcessor();
        VideoSDK videoSDK = VideoSDK.getInstance();
        videoSDK.registerVideoProcessor("customVideoProcessorName", customVideoProcessor);
    }
}

class CustomVideoProcessor implements VideoFrameProcessor {
    @Override
    public VideoFrame onFrameCaptured(VideoFrame videoFrame) {
        // Apply your effect here, and return the frame to send.
        return videoFrame;
    }
