Description Jean-Yves Avenard [:jya] 2023-11-02 23:40:24 PDT

sub-task of bug 264134

We have three MSE implementations in our tree:
- Cocoa/AVFObjC
- Mock
- GStreamer

In a lot of instances, all three duplicates the same code. It makes it harder to maintain and too easy to introduce discrepancy between the three implementations.

Let's move to their respective base classes what can be moved.
