It is possible for playback to be stuck when there is failure in loading further data, while the player is required to load more due to the buffered duration being under `DefaultLoadControl.bufferForPlayback`. Therefore, we check if there is any loading error in `isLoadingPossible`, so that the player will allow the playback of the existing data rather than waiting forever for the data that can never be loaded.
