Not found resource to use video compress

I am trying to use video compress by using Litr library i implement the library
i create obj for mediatranformer
use the method .transform implement the listner but didnt get how use listner and implement compression

please share any resources

The issue names LiTr, MediaTransformer, transform, and the listener. Start by reading the library's existing MediaTransformer usage documentation or examples; done would be a clear resource explaining how to register the listener and perform video compression.
