flutter拉流

1,引入vlc

flutter_vlc_player: 

2,代码

import 'package:flutter/material.dart';


import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';

class LivestreamPlayer extends StatefulWidget {

  @override
  LivestreamPlayerState createState() => LivestreamPlayerState();
}

class LivestreamPlayerState extends State<LivestreamPlayer>
    with AutomaticKeepAliveClientMixin , WidgetsBindingObserver {
  late VlcPlayerController _controller;

  @override
  bool get wantKeepAlive => true;

  @override
  void initState() {
    super.initState();
    //initialize the player with downstreamUrl
    _controller = VlcPlayerController.network("rtmp://:/live/stream",
        options: VlcPlayerOptions());
    WidgetsBinding.instance?.addObserver(this);
  }

  @override
  void dispose() async {
    _controller.dispose();
    WidgetsBinding.instance?.removeObserver(this);

    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    super.build(context);
    //return the VlcPlayer Widget
    return VlcPlayer(
      controller: _controller,
      aspectRatio: 9 / 16,
      placeholder: const Center(child: CircularProgressIndicator()),
    );
  }
}

ios配置---------------------- If you're unable to view media loaded from an external source, you should also add the following:

<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

For more information, or for more granular control over your App Transport Security (ATS) restrictions, you should read Apple's documentation.

Make sure that following line in <project root>/ios/Podfile uncommented:

platform :ios, '9.0'

NOTE: While the Flutter video_player is not functional on iOS Simulators, this package (flutter_vlc_player) is fully functional on iOS simulators.

To enable vlc cast functionality for external displays (chromecast), you should also add the following:

<key>NSLocalNetworkUsageDescription</key>
<string>Used to search for chromecast devices</string>
<key>NSBonjourServices</key>
<array>
  <string>_googlecast._tcp</string>
</array>
