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

目前使用的服务端是 srs_stack

加入依赖

pubspec.yaml中加入依赖 -> 官方地址

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

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文章来源地址https://www.toymoban.com/news/detail-759698.html
