fijkplayer flutter 直播流播放
fijkplayer flutter 直播流播放
fijkplayer 是 ijkplayer 的 Flutter 封装, 是一款支持 android 和 iOS 的 Flutter 媒体播放器插件, 由 ijkplayer 底层驱动。
通过纹理(Texture)接入播放器视频渲染到 Flutter 中。
前言

fijkplayer: ^0.11.0
配置(解决延迟)
连上视频流可能会发现有差不多10秒的播放延迟, 以下是有一些调整参数可以试下调整
我测试配置了analyzeduration: 1)
后延迟就有很大改善(大概1秒多rtmp
方案)
如果需要做到1秒
内的延迟可能得用srt协议
注意:需要做到1秒内,录制端,传输和播放端均需要做好优化
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);
测试源码
官方的
demo
可能是基于久版本的flutter
的,我无法直接用, 遇到有问题的可以用以下源码测试
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});
_VideoScreenState createState() => _VideoScreenState();
}
class _VideoScreenState extends State<VideoScreen> {
final FijkPlayer player = FijkPlayer();
_VideoScreenState();
void initState() {
super.initState();
player.setDataSource(widget.url, autoPlay: true);
// 解决播放延迟
// player.setOption(FijkOption.playerCategory, "fflags", 'nobuffer');
