fijkplayer flutter 直播流播放

fijkplayer 是 ijkplayer 的 Flutter 封裝， 是一款支持 android 和 iOS 的 Flutter 媒體播放器插件， 由 ijkplayer 底層驅動。
通過紋理（Texture）接入播放器視頻渲染到 Flutter 中。

pubspec.yaml中加入依賴 -> 官方地址

fijkplayer: ^0.11.0

配置(解決延遲)

連上視頻流可能會發現有差不多10秒的播放延遲, 以下是有一些調整參數可以試下調整
我測試配置了analyzeduration: 1)后延遲就有很大改善(大概1秒多rtmp方案)
如果需要做到1秒內的延遲可能得用srt協議

注意:需要做到1秒內,錄制端,傳輸和播放端均需要做好優化

    player.setOption(FijkOption.playerCategory, "fflags", 'nobuffer');player.setOption(FijkOption.playerCategory, "fast", 1);player.setOption(FijkOption.playerCategory, "framedrop", 5);player.setOption(FijkOption.playerCategory, "start-on-prepared", 1);player.setOption(FijkOption.formatCategory, "max-buffer-size", 0);player.setOption(FijkOption.playerCategory, "packet-buffering", 0);player.setOption(FijkOption.formatCategory, "analyzeduration", 1);player.setOption(FijkOption.formatCategory, "analyzemaxduration", 100);player.setOption(FijkOption.formatCategory, "rtsp_transport", 'tcp');player.setOption(FijkOption.formatCategory, "probesize", 100);player.setOption(FijkOption.formatCategory, "flush_packets", 0);player.setOption(FijkOption.playerCategory, "reconnect", 5);

測試源碼

官方的demo 可能是基于久版本的flutter的,我無法直接用, 遇到有問題的可以用以下源碼測試

import 'package:fijkplayer/fijkplayer.dart';
import 'package:flutter/material.dart';void main() {runApp(VideoScreen(url: 'rtmp://192.168.31.91/live/test110'));// runApp(VideoScreen(url: 'http://192.168.31.91:2022/live/test110.flv'));// runApp(VideoScreen(url: 'http://192.168.31.91:2022/live/livestream-trans.flv'));
}class VideoScreen extends StatefulWidget {final String url;VideoScreen({required this.url});@override_VideoScreenState createState() => _VideoScreenState();
}class _VideoScreenState extends State<VideoScreen> {final FijkPlayer player = FijkPlayer();_VideoScreenState();@overridevoid initState() {super.initState();player.setDataSource(widget.url, autoPlay: true);// 解決播放延遲// player.setOption(FijkOption.playerCategory, "fflags", 'nobuffer');// player.setOption(FijkOption.playerCategory, "fast", 1);player.setOption(FijkOption.playerCategory, "framedrop", 1);// player.setOption(FijkOption.playerCategory, "framedrop", 5);// player.setOption(FijkOption.playerCategory, "start-on-prepared", 1);// player.setOption(FijkOption.formatCategory, "max-buffer-size", 0);// player.setOption(FijkOption.playerCategory, "packet-buffering", 0);player.setOption(FijkOption.formatCategory, "analyzeduration", 1);// player.setOption(FijkOption.formatCategory, "analyzemaxduration", 100);// player.setOption(FijkOption.formatCategory, "rtsp_transport", 'tcp');// player.setOption(FijkOption.formatCategory, "probesize", 100);// player.setOption(FijkOption.formatCategory, "flush_packets", 0);// player.setOption(FijkOption.playerCategory, "reconnect", 5);}@overrideWidget build(BuildContext context) {return MaterialApp(theme: ThemeData.from(colorScheme: ColorScheme.fromSeed(seedColor: Colors.red,brightness: Brightness.light,),useMaterial3: true,),home: Scaffold(appBar: AppBar(title: const Text('測試視頻流播放'),),body: Builder(builder: (context) {return Column(children: [Row(mainAxisAlignment: MainAxisAlignment.center,children: [IconButton(onPressed: () {// player.dispose();player.reset();player.setDataSource(widget.url, autoPlay: true);// player.start();},icon: Icon(Icons.not_started),color: Colors.green,),IconButton(onPressed: () {player.stop();},icon: Icon(Icons.stop),color: Colors.red,),IconButton(onPressed: () {var playable = player.isPlayable();print('playable: ${playable}');showSnackBar('playable: ${playable}', context: context);},icon: Icon(Icons.safety_check),color: Colors.blueAccent,),],),FijkView(player: player,width: 400,height: 300,),]);},),),);}@overridevoid dispose() {super.dispose();player.release();}void showSnackBar(String text, {required BuildContext context}) {ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text(text, style: const TextStyle(fontSize: 12))),);}
