How to set FIFO value

Vasanth M.Vasanth
Hi,

How to set exact FIFO value for live streaming?

Current value fifo_size=25000000

Is this correct?

Thanks & Regards

Assuming you mean the fifo_size parameter for the udp protocol:

https://ffmpeg.org/ffmpeg-protocols.html#udp

  "udp://hostname:port[?options]

   options contains a list of &-separated options of the form key=val."

So
$ ffmpeg -i input -f mpegts udp://hostname:port?fifo_size=25000000

The default value is listed below in the documentation as 7*4096 = 28672
packets of size 188 (= 5390336 bytes).

You weren't precise enough about what you are trying to do and what
your issue is.
