The rawdata plugin for agora_rtc_engine

agora_rtc_rawdata

The rawdata plugin for agora_rtc_engine.

Important

The plugin only exports four methods to the dart layer that can register or unregister the observer.

class AgoraRtcRawdata {
  static const MethodChannel _channel =
      const MethodChannel('agora_rtc_rawdata');

  static Future<void> registerAudioFrameObserver(int engineHandle) {
    return _channel.invokeMethod('registerAudioFrameObserver', engineHandle);
  }

  static Future<void> unregisterAudioFrameObserver() {
    return _channel.invokeMethod('unregisterAudioFrameObserver');
  }

  static Future<void> registerVideoFrameObserver(int engineHandle) {
    return _channel.invokeMethod('registerVideoFrameObserver', engineHandle);
  }

  static Future<void> unregisterVideoFrameObserver() {
    return _channel.invokeMethod('unregisterVideoFrameObserver');
  }
}

The plugin changes the color of the video stream by the default:

• Change local video to green
• Change remote video to pink

You can find the code at:

• Android: AgoraRtcRawdataPlugin.kt
  • Local video: onCaptureVideoFrame
  • Remote video: onRenderVideoFrame
• iOS: AgoraRawdata.swift
  • Local video: onCapture
  • Remote video: onRenderVideoFrame

If you can program with C++, you should process raw data on the C++ layer to improve performance and remove code about calling Android and iOS.

You can find the code at:

• Android:
  • Audio: AudioFrameObserver.cpp
  • Video: VideoFrameObserver.cpp
• iOS:
  • Audio: AgoraAudioFrameObserver.mm
  • Video: AgoraVideoFrameObserver.mm

Installation

You should fork this repository, and modify the code to implement your requirement, such as use third-party beauty SDK.

Usage

import 'package:agora_rtc_engine/rtc_engine.dart';
import 'package:agora_rtc_rawdata/agora_rtc_rawdata.dart';

_initEngine() async {
    var engine = await RtcEngine.create(config.appId);
    await AgoraRtcRawdata.registerAudioFrameObserver(
        await engine.getNativeHandle());
    await AgoraRtcRawdata.registerVideoFrameObserver(
        await engine.getNativeHandle());
}
