How to reduce the latency of a stream from the usb camera

[stefantripac]

It is possible tor reduce the latency of the Flayleaf when Open stream camera with input string : "fmt://dshow?video=PC-LM1E&video_size=640x480&framerate=30" ?

After 10 minutes of working the lag varies from 1 to 18 secs. the bitrate is 13,590 Kbps and codec : mjpeg, read from ShowDebug window.

Using VLC wit the same camera the result is almost the same,

The camera with other windows applications like Microsoft Teams work without any visible lag.

The camera options read with ffmpeg are:

Can I do something in flyleaf configuration to reduce this live stream lag ?

Thank you.

Hi @stefantripac, yes there are a number of options for latency. Mainly set this:

Config.Player.MaxLatency = TimeSpan.FromMilliseconds(500).Ticks;

You can search the issues / discussions for more info, here one related #388

It work , Thank you.
