How to Screen record a particular ViewGroup (Relative Layout), which can contain a video views,surface views, textviews, etc

I am making a view recorder class.Which can record a video(.mp4) of any view or view group(relative layout), and also record everything that is present inside this view group.

I have looked into mediaProjections API. But it screenRecords everything that is present on the screen including status bar etc.

I also tried using this solution.https://github.com/z4hyoung/ViewRecorder/tree/masterBut As my requirement is that my relative layout contains a video view. It records it as black container, because the video view extends a surface view and not able to get the content of the surface view.

This what my code looks like,This is the xml file I want to record the rootView here and all the children inside it. But not any sibling of rootView.

Looking for a generic solution to create a view/viewgroup recorder that can also record contents of the video view or any other surface view present inside as children of the view group.
