Is it possible to change YouTube videos link through firebase with stock/default YouTube player in application?
Yes, it is possible.
Can you tell me how ?
Lets begin with basics of firebase database,
Watch this
Create a bucket and tag.
Under that tag enter your YouTube url.
Now get url as get value from firebase whenever you want in your app.
When you change url from firebase then it is automatically changed in your app.
