HLS question
admin Staff asked 8 years ago
We use HLS streaming for live video, we would like to decrease delay time to real time, so we choose chunkLength=2s in command to EvoStream.
Results : As long as it’s displaying stream video, it delays more.
For example, when it starts display, it delays 10s.
After a while, it delays 14s -> 18s -> 26s -> 35s -> 55s …
Could you help to check this issue more ?
I guess the issue comes from playlist.m3u8 ? It looks like 2 seconds in real video that will be displayed/created in ~ 3 seconds of TS files. So as long as it’s displaying stream video, the difference is longer.

Hi,
Please try reducing the key frame interval of your source video to less than 2 seconds. If your key frame interval is more than 2 seconds, the actual chunk length will be more than 2 seconds more often than not.
Cheers,
Don

I created the same question in another thread. We always set I-Frame interval = 1s (minimum)
