Question

Please let me know the difference between prepareToPlay & play Methods in MPMoviePlayerController at the time of Video Play.

The syntax are:

[moviePlayer prepareToPlay];

And

[moviePlayer play];

Answer 1

As Method say that

prepareToPlay - is not starting to play but it is under process for play whatever (video/audio).

play - says that it is do string to play whatever (video/audio).

as Document say:

play

Initiates playback of the current item. (required)

- (void)play  

Discussion
If playback was previously paused, this method resumes playback where it left off; otherwise, this method plays the first available item, from the beginning.

If a movie player is not prepared for playback when you call this method, this method first prepares the movie player and then starts playback. To minimize playback delay, call the prepareToPlay method before you call this method.

To be notified when a movie player is ready to play, register for the MPMoviePlayerLoadStateDidChangeNotification notification. You can then check load state by accessing the movie player’s loadState property.

prepareToPlay

Prepares a movie player for playback. (required)

- (void)prepareToPlay

Discussion
If a movie player is not already prepared to play when you call the play method, that method automatically calls this method. However, to minimize playback delay, call this method before you call play.

Calling this method may interrupt the movie player’s audio session. For information on interruptions and how to resond to them, see Audio Session Programming Guide.
