Live broadcast streaming delay #1499

Describe the question Hi,

I setup the AVideo Server in LAN and then do live streaming (RTMP).

The problem is when I compare Video streaming output with the video source. It delay about 35-40 sec. Is it possible to reduce the latency time close to video source?

Thanks & BR,

Yes we can achieve 2 seconds sub latency

Hi Sriman,

So, It depend on the Encoder setting. Right? I tried set the parameter same as your picture. But the latency still about 10-12 sec.

obs

Thanks & BR, Pond

No other than this I haven't configured anything, I have served through servers in which I could achieve 1.5 - 2 seconds delay, you are using LAN so it should be below 1 second.

Not only. Screen size, encoding, decoding, internet speed + latency, etc. I use Nginx + RTMP + OBS, 1280px video, 128k audio, remote server, my latency is exactly 40 seconds, always.
