RTMP streaming and camera plugin.
This plugin is an extension of the flutter camera plugin to add in rtmp streaming as part of the system. It works on android and iOS (but not web).
This means the API Is exactly the same as the camera and installation requirements are the same. The difference exists in an extra API that is startStreaming(URL), it takes an RTMP URL and starts streaming to that specific URL.
For android I use rtmp-rtsp-stream-client-java and for iOS I use HaishinKit.swift
First, add camera
as a dependency in your pubspec.yaml file.
Add two rows to the ios/Runner/Info.plist
:
Privacy - Camera Usage Description
and a usage description.Privacy - Microphone Usage Description
and a usage description.Or in text format add the key:
<key>NSCameraUsageDescription</key>
<string>Can I use the camera please?</string>
<key>NSMicrophoneUsageDescription</key>
<string>Can I use the mic please?</string>
Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle
file.
minSdkVersion 21
Need to add in a section to the packaging options to exclude a file, or gradle will error on building.
packagingOptions {
exclude 'project.clj'
}
Here is a small example flutter app displaying a full screen camera preview.
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:camera/camera.dart';
List<CameraDescription> cameras;
Future<void> main() async {
cameras = await availableCameras();
runApp(CameraApp());
}
class CameraApp extends StatefulWidget {
@override
_CameraAppState createState() => _CameraAppState();
}
class _CameraAppState extends State<CameraApp> {
CameraController controller;
@override
void initState() {
super.initState();
controller = CameraController(cameras[0], ResolutionPreset.medium);
controller.initialize().then((_) {
if (!mounted) {
return;
}
setState(() {});
});
}
@override
void dispose() {
controller?.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
if (!controller.value.isInitialized) {
return Container();
}
return AspectRatio(
aspectRatio:
controller.value.aspectRatio,
child: CameraPreview(controller));
}
}
