Unable to fetch video player elements in appium

I am trying to automate an android app that provides media content on OTT, say like netflix.

Now the automation tool I am using is Appium with java.

I am unable to validate the video player parameters. As soon as the video player is launched, the UI automator is unable to fetch the screenshot of the device.

I have been stuck with this for a while now. Would really appreciate any help I can get on this.
