YouTube video change through firebase

Can any one help me?
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 ?

I Have Made This Type Of App But I Have Used Airtable Spreadsheets

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.
