Anyway to reduce upto 5 secs latency in HLS

Hi,

By using properties listed here i reduced my latency from 30secs to 12 secs in HLS. But client required <5 secs . Any idea/suggestion?? Thanks in advance

Hi,

The chunks for HTTP streaming are created on a keyframe, if the keyframe is every 1 second the cupertinoChunkDurationTarget can also be 1 second.

I don’t think you will be able to get a latency 5 seconds or below with HLS due to how it works, you’re always 3 chunks behind the actual live event.

The best way to test this is to make everything local and see what the delay is when using a stream which has 1 second keyframe intervals and the cupertinoChunkDurationTarget is set to 1000 (1 second).

Playback of Apple HLS can be done using VLC player which could keep everything local.
