I need to know if at an specific moment the MPMoviePlayerController is playing.
In iphone 3.0 it is not firing the MPMoviePlayerContentPreloadDidFinishNotification.
Does anyone knows any solution?
Thanks in advance!
So thanks for the answer.
I fix this so I will post the answer.
The answer is that MPMoviePlayerContentPreloadDidFinishNotification is NOT FIRED if you invoke play() right after the initialization.
To have MPMoviePlayerContentPreloadDidFinishNotification which works ok you have to invoke the "play()" method of the MPMoviePlayerController when the MPMoviePlayerContentPreloadDidFinishNotification is fired ( I mean in the MPMoviePlayerContentPreloadDidFinishNotification method ). In this case it always works.
Tested on 3.0, 3.1 and 3.1.2
Same question (but no answer) here and several other reports can be found on other sites (e.g. here)
Not ideal, but it seems targeting 3.1 solves the problem.
A workaround maybe to set the MPMoviePlayerController property scalingMode to something other than the default MPMovieScalingModeAspectFit ( e.g. MPMovieScalingModeNone and make sure your video is correct size) before calling play and then hook the MPMoviePlayerScalingModeDidChangeNotification event instead. it seems to get called (more than once!) as soon as the movie starts playing. Of course it will also be called if the user changes the scaling mode manually, so code for this. It's dirty but may help you?

Ok I want to disable the idletimer in my app. I put the code below in appdelegate in the applicationDidFinishLaunching method, and it works fine (the device remains unlocked)
[application setIdleTimerDisabled:YES];
Though, when I play a music through MPMusicPlayer methods, the idletimer seems to be enabled back again... and soon the device goes into dimmed mode and soon after, "locked" mode.
I tried to find in google for other methods, but ultimately there are NONE that are effective. I also tried putting the above code in another function and calling that function every seconds using NSTimer when the music is playing, but to no avail. It just won't work.
How can I solve this issue?
Ugh. I hate answering my own questions. But here you go, the answer is here:
How to stop MPMusicPlayerController from enabling screen locking
See the reply from henning. Works like a charm!
I want to play videos. I am using MPMoviePlayer, but I don't want to use the controls provided by MPMoviePlayer. So I am trying to create my own custom controls. All the functionality like play, pause, fullscreen, forward, backward are done. The only problem is with the scrubber. I am having one UISlider but I don't know how exactly work with this. How to track the currently playing video time? How to play video from where I will slide the thumb of slider?
If anyone knows this kindly help me in this.
Thanks in advance.
I was having a similar problem. I figured out how to create custom movie controls and put it up on github. Let me know if that helps. Feel free to ask me any questions if you want details.
First, we should note that all of this is possible in iOS 3.2+, if you are OK not to support iOS 3.1.x.
In iOS 3.2+, MPMoviePlayerController implements the MPMediaPlayback protocol, meaning that it responds to play, stop, etc., all the controls you would expect -- sounds like you already have some of this working. Please see the reference for the MPMediaPlayback protocol.
To get the MPMoviePlayerController to stop showing its own controls, do this on initialization:
yourPlayer.controlStyle = MPMovieControlStyleNone;
Finally, to get the scrubber to work, you need to set the UISlider valueChanged: callback to something, and update the value of currentPlaybackTime property. If you want to seek 10 seconds in:
yourPlayer.currentPlaybackTime = 10;
I have an app that's worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version of the 4.0 beta up until the 4.0 GM this has stopped working. When I load a movie now I get the following error: :Plug-in handled load" and the movie never displays.
Is this a known issue? Am I doing something wrong in 4.0?
I figured this out. It appears to be an issue with iOS4 not being backward compatible with a UIWebView created with 'init' rather than 'initWithFrame'. In 2.0 - 3.1.3, you could only show video in a UIWebview as full screen. I think this is why it didn't matter if you called 'init' -- the movie player would kick in and go fullscreen. However, in 3.2 and higher you can now inline video in a UIWebView so you have to call initWithFrame and give it something like [[UIScreen mainScreen] bounds] so there's a visible view. Not quite sure if this is bull or not but seems to be the case.
I got a situation of "this movie could not be played" when playing a video clip.
This happened when recorder was just used. And this would NOT happen when player was just used.
Then I set audio session category to kAudioSessionCategory_AmbientSound after recorder finished.
This problem was solved after I did that.
Simply just ignore it. No harm in doing so.
if (![error.localizedDescription isEqualToString:#"Plug-in handled load"])
At least in PhoneGap's ChildBrowser, the didFailLoadWithError method handles and displays this message. Simply don't display the error, problem solved, but in this specific case there are two 'done' buttons to press before you get back to the application.
I was trying to go through the iPhone's sample code for mediaplayer.
I want to be able to capture the amount of time the media player has played the video. The duration at which the media player has stopped. Is there a method or property that will tell me the duration of play of the media??
Unfortunately the current API for MPMoviePlayerController allows basically no control. You can tell it to play and stop... otherwise where's a delegate method so you can be notified when the movie finishes playing and that's it, there's no additional controls. (a real bummer)
However, while we cant discuss the new 3.2 SDK yet, I'll give you a tip and say go look at the documentation of MPMoviePlayer in 3.2 and I think you'll be happy.
http://developer.apple.com/iphone/prerelease/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html
moviePlayer.currentPlaybackTime
It's not possible to do KVO on it but you could do like me and create an scheduledTimer which updates every second to check what the current playbacktime is and update your graphics accordingly :)
Yes, You can use the property "duration" defined by MPMediaPlayerController. Plese try it out and check the output. U can refer the here duration property
When you launch a video and IMMEDIATELY press "Done" the MPMoviePlayerController will exit, however the video still plays in the background (you can hear the audio). It works fine if you allow the video to begin playing before you hit the "Done" button.
Does anybody know a workaround for this?
Try calling stop on your MPMoviePlayerController instance when the view controller that spawned the movie receives its viewDidAppear: (or viewWillAppear:) methods
While, so far, I've also found MPMoviePlayerController somewhat erratic, I imagine just releasing the object (after listening to a MPMoviePlayerPlaybackDidFinishNotification) would help.
Update: This seems to be a known 3.0 bug. I was unable to find a workaround
