# agora_rtc_rawdata

A flutter plugin that demostrate how to processing rawdata with [agora_rtc_engine](https://pub.dev/packages/agora_rtc_engine).

## Important

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

```dart
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 example 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](android/src/main/kotlin/io/agora/agora_rtc_rawdata/AgoraRtcRawdataPlugin.kt)
  * Local video: `onCaptureVideoFrame`
  * Remote video: `onRenderVideoFrame`
* iOS: [AgoraRawdata.swift](ios/Classes/SwiftAgoraRtcRawdataPlugin.swift)
  * Local video: `onCapture`
  * Remote video: `onRenderVideoFrame`

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

You can find the code at:

* Android:
  * Audio: [AudioFrameObserver.cpp](cpp/android/AudioFrameObserver.cpp)
  * Video: [VideoFrameObserver.cpp](cpp/android/VideoFrameObserver.cpp)
* iOS:
  * Audio: [AgoraAudioFrameObserver.mm](ios/Base/AgoraAudioFrameObserver.mm)
  * Video: [AgoraVideoFrameObserver.mm](ios/Base/AgoraVideoFrameObserver.mm)

## Installation

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

## Usage

```dart
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());
}
```
