Broadcasting camera video content results in black screen when streaming on Restream.io

[Aniketbokre97]

Im using Haishinkit library for live streaming using MTHKView

Im using this code for attach screen, rtmpStream.attachScreen(ScreenCaptureSession(viewToCapture: view))
Inside the main view, there is one camera view.
I have share the whole screen to the streaming server.
when i start streaming on Restream.io , the camera screen not visible .

Expected output : Stream view as same as iphone view.

ScreenCaptureSession uses the https://developer.apple.com/documentation/uikit/uiview/1622589-drawhierarchy method internally.
This method can't capture a gpu-based content such as AVSampleBufferLayer or AVPlayer video content.
This is specification. I can't fix it. see alos #812
