MPMoviePlaybackState always Paused

[rocxteady]

Hello. I am trying to get mediaplayer situations when it is paused or stoped. But I can't receive correct notification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stateDidChange:) name:IJKMoviePlayerPlaybackStateDidChangeNotification object:self.player];

But the state is always "MPMoviePlaybackStatePaused".

Please help.

Which player did you use, IJKMPMoviePlayerController or IJKFFMoviePlayerController?
For IJKMPMoviePlayerController, did you set shouldAutoplay=YES?
Or could you paste corresponding code here?

I am using IJKFFMoviePlayerController. I did not set shouldAutoPlayer=YES. Now I did but same result.

Here is my code:

inViewDidLoad:

self.player = [[IJKFFMoviePlayerController alloc] initWithContentURL:theMovieURL withOptions:nil];
[self.player setShouldAutoplay:YES];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stateDidChange:) name:IJKMoviePlayerPlaybackStateDidChangeNotification object:self.player];

self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.player.view.frame = self.view.bounds;

self.view.autoresizesSubviews = YES;
[self.view addSubview:self.player.view];
[self.view sendSubviewToBack:self.player.view];

[self.player prepareToPlay];
[self.player play];

notification method:
IJKFFMoviePlayerController *moviePlayer = notification.object;
if (moviePlayer.playbackState == MPMoviePlaybackStatePlaying){
//here playbackState always paused
[_loadingIndicatorView stopAnimating];
}

Now, "prepared" state is treated as "playing"

Thank you for that. And How do I know player is buffering at any time?

        // [self changeBufferingStatus:YES]; show buffering progress
    }

    NSLog(@"loadStateDidChange %d", (int)(long)_player.loadState);
}

Is this update for IJKMPMoviePlayerController?

I need for IJKFFMoviePlayerController. My player does not get triggered while buffering. :(

Both IJKMPMoviePlayerController and IJKFFMoviePlayerController are OK in latest IJKMediaDemo on master.
Can you receive other notification?

Add some sleep() around av_read_frame() to demonstrate slow network.
Or add some breakpoint in IJKFFMoviePlayerController postEvent.

While player is playing url, I change stream from my server but in the app I can’t get buffer notification for new stream, my new stream plays automatically. I can’t know when it started to play.

avmsg->what cvalues always “502 or 503 or 504” when I change the stream. Like it never changed.

If you mean FFP_MSG_BUFFERING_START(END) messages, stalled buffering only happens when there is not enough data to decode at all.

“502, 503, 504” is designed to indicate pre-fetching progress displayed on UI, such as second progress in slider, no only for stalled buffering, but also for normal pre-fetching.

You should make the streaming slowly enough to reproduce FFP_MSG_BUFFERING_START(END) messages

Can this issue be closed?

Yes, thank you.
