Appium - How to verify Player controls (Play, pause, volume, FS ?)

Hi,

This is my first post and new to appium. Trying to solve a problem that will help me automate this application on Android.

We have Instant articles in Facebook which in turn navigates you to in-app browser within the application. This pages shows some videos. But when using Uiautomatorviewer, the elements i can use is just class and package-name. At this point i want to do actions like Play, Pause, Volume etc on the player itself and then verify these actions.

How am i able handle this using appium ? I am not trying to record a video, all i want to verify is player controls. Any help in this case is appreciated. I have attached a screenshot of how the in-app browser looks like within the application.

Thanks

Any help in how to identify this web view elements within this hybrid app would be of great help. Looking for some solutions ? Thanks in advance.
