• Activity and Fragment support
• Decreasing bitrate when connection is slow
• Switching the main/front cameras
• Scaling types, aspect ratio correction, and full handling lifecycle
• Handling errors
• Simple interface
• Fast performance
• No dependencies

How to use:

• Contact with us for AVLib sdk

• Add AVLib sdk into your project (It's one aar file without any dependencies)

dependencies {
	implementation(name: 'AVlib2.0.0', ext: 'aar')
}

note: inside AvLib SDK used only one dependency androidx.appcompat:appcompat:1.1.0

• For broadcasting from android cam use CameraStreamer class. Create instance and attach 'broadcast view'.

Camera view from layout

<com.onix.avlib.view.CameraStreamView
    android:id="@+id/camera_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

private val streamer = CameraStreamer(CamType.MAIN)

override fun onCreate(savedInstanceState: Bundle?) {
   super.onCreate(savedInstanceState)
   retainInstance = true
   streamer.onCreate(activity, savedInstanceState)
}

override fun onCreateView(...) {
...
   streamer.bindView(binding.cameraView, PreviewScaleType.CENTER_CROP)
   streamer.setStreamListener(this)
   return view
}

• add lifecycle method onSaveInstanceState :

override fun onSaveInstanceState(outState: Bundle) {
   super.onSaveInstanceState(outState)
   streamer.onSaveInstanceState(outState)
}

• Сustomize streamer before start: setVideoBitrate(VideoBitrate bitrate), setAudioBitrate(AudioBitrate bitrate), setPreviewSize(PreviewSize size), etc.

override fun onInitCompleted() {
    streamer.setServerUrl(serverUrl)
}

• Start/Stop broadcasting:

streamer.startStreaming();

streamer.stopStreaming();
