>+        Make sure that MediaRecorderPrivateAVFImpl takes a Ref<MediaRecorderPrivateWriter> as member,
>+        as the latter is a ref counted object.
>+        Made some refactoring to return early in case of error.
>+
>+        Also made sure that in the case of a MediaRecorder stopped by a track removal in the recorded stream
>+        the MediaRecorder will stop listening for its tracks.
>+        Otherwise, the tracks will continue calling the MediaRecorder even after it is dead.
