A casting is laggy using NDI SDK

I’m trying to use NDI SDK to cast a view of the player.

There is lag in that case.

Firstly, I built a test application with Unity on a smartphone (This is an Android OS). The result is working well.

But I built my a Nreal Light application then the lag was happened like video that I linked. Is there any wrong project settings?

Is this in real-time live streaming?

Yes, it’s in real-time! Do you know something?
