WebRTC taking 4+ seconds to do handshake after publish call

[Divyanshu Kalra]

After calling publish, it takes 4ish seconds to start publishing, is there any way to reduce this? I am working on a app for which it is critical to start publish as soon as possible. Any help will be appreciated :)

Hi kalradivyanshu,

Which version are you using? Generally, it's related to network stability. Could you please check your network parameters in this link?

Hey,

 

I have attached the report of webrtc test. I dont think it is due to network params. I did some digging, and it seems takeCandidate is being exchanged multiple time, as mentioned here: https://ant-media-docs.readthedocs.io/en/latest/WebRTC-Developers.html#publishing-webrtc-stream . Is there a way to reduce this? It can help cut down the time. 

Version: ant-media-server-enterprise-2.1.1-20200902_1011

Hi Divyanshu,

   I think you are right. I have similar observations. We are publishing from us west and server is in india. Aws latency is 600-700 ms so total setup time is around 3 seconds. When we tried with aws west servers (aws latency 50ms) then  total  setup time is 0.7 seconds. So call setup time depends on no of exchanges (in setup) and how far is server located 

Thanks

Hi nagendra.cse,

Thanks for the clarification. Yes, server location one of the most important things for the streaming as I mentioned this article.
