Lowest possible latency setting? #2532
-
Hello, If I have an endpoint who's LINK RTT is below 2s... what is the lowest support latency setting with srt-live-transmit? Can I go as low as 6ms? I believe there used to be a hard floor prior to v1.5 that was around 30ms. |

Yes, you can go to 6 ms. Starting from v1.5.1 (with the new receiver buffer implementation) the lowest possible is 1 ms, because 0 is a special value for the default latency of 120 ms. |

Thank you for the response. This makes sense. Much appreciated. |

See SRTO_LATENCY.
Still, the lower you go, the more chances some packet loss remains unrecovered. The recommended latency value for wired networks is 3 to 4 times RTT.
