关于MDK拉取RTSP码流延迟大的问题 #79
Comments
还没有。QGC是什么? |
qgroundcontrol,一款可以播放RTSP的低延迟地面站软件。不知道您是否有测试RTSP的延迟呢,我发现有一点点大

https://github.com/wang-bin/mdk-sdk/wiki/Typical-Usages#low-latency-live-stream 需要提供带时间的日志判断哪里耗时了。 我局域网里测一台电脑ffmpeg+zlmediakit推流一台播放延迟在1s内 |

我在QT环境下面测试了MDK RTSP的延迟,对比了VLC/FFMPEG/QGC 框架。VLC的延迟大概在4秒左右,QGC可以低至0.9s,但是MDK设置FFMPEG作为解码器的延迟大概在2.5s左右。我设置了如下参数:
setVideoDecoders({"FFmpeg"})
SetGlobalOption("avformat", "fflags=+nobuffer:analyzeduration=10000:probesize=1000:fpsprobesize=0:avioflags=direct");
setBufferRange(0, 1000, true);
不知道还有没有其他设置选项可以进一步降低延迟?
