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;
