VideoPlayerCallBack is the callback class for VideoPlayer.
The callback is passed to the player from VideoPlayer::open and used in the whole life time to return open result or play status. You should implement operator() to get the result.
|virtual void||operator() (VideoPlayer::Status status) = 0|
virtual void operator() (VideoPlayer::Status status)
status indicates different status of the player. A successful open will have a status of
kVideoReady and when the play reaches the end, status will be
kVideoCompleted; If any error happens, the status will be
kVideoError. See VideoPlayer::Status for more description of different status.
