You're constructing a new PendingTask -- its constructor takes the mutex,
initializes its members while holding its mutex (totally unnecessary, since
during the constructor execution no other code has received a reference to that
instance). Then, the constructor withdraws the mutex, and this code runs
operator=() on PendingTask, which -- now without any mutex protecting anything
-- swaps the data members of the new instance with the members of the old
instance.

> +    void invalidateCachedPositionOnNextIteration() const;

invalidateCachedPositionOnNextIteration() can be private, since it's only used
by MediaPlayerPrivateGStreamer. Note playbackPosition() is also private. Both
are things that could be changed easily if ever needed.
