I'm trying to make an application that plays gapless and loops with  C.

There are a few things I don't understand.

How to dynamically change the next filesrc after playing the first filesrc?
How to dynamically play the next filesrc with gapless?
How to dynamically loop play?
Is it difficult for a beginner to understand these and make an application?
