Sometimes your system may display an error code indicating that mpmovieplayercontroller is a dedicated memory leak. There can be several reasons for this problem.

The cache used by the iPad due to preloading the video stream has not been completely cleared.Whenever this page was cleared and published using the YouTube player, there was some cached storage left in the storage you allocated after clearing. For large videos, it can even go as high as 50MB.

If the page was considered reopened, the cache is probably reassigned. But it’s still frustrating because you want a great clean exit situation, which means that when this web page is closed and cleared, all the space used by that page needs to be freed up, including the memory used for caching. A new video stream is being used ….!

After some serious effort, this bespoke series appears to be doing its job now:

  [[NSNotificationCenter defaultCenter] removeObserver: self                                                    name: MPMoviePlayerPlaybackDidFinishNotification                                                  Theme: myMoviePlayer];    [[NSNotificationCenter defaultCenter] removeObserver: self                                                    name: MPMoviePlayerDidExitFullscreenNotification                                                  Theme: myMoviePlayer];    [[NSNotificationCenter defaultCenter]removeObserver: self                                                    name: MPMoviePlayerLoadStateDidChangeNotification                                                  Theme: myMoviePlayer];    [[NSNotificationCenter defaultCenter] removeObserver: self                                                    name: MPMovieDurationAvailableNotification                                                  Theme: myMoviePlayer];    [pause myMoviePlayer];    myMoviePlayer.initialPlaybackTime -1; = [myMoviePlayer-stop];    myMoviePlayer. = start playback time -1;    [myMoviePlayer.view removeFromSuperview];   [myMoviePlayer version];

1 – DELETE all notifications you use for your personal video player.

What in my case means the video cache on my iPad (OS 4.2).and leaving the memory situation associated with the peak equal to the height before opening the golfer’s video page. So come in and out of the same memory.

Question

I ran into all these 3MB mallocks created by CoreVideo in the Groups app for iPad after publishing the MPMoviePlayerController object. Done

I’m pretty sure the drive will be closed before exiting so that it actually starts up memory and ejects locomotives correctly. The problem may be that the instrThe tool keeps showing this malloc, which is often not published (nor used by me directly in my code).This is indeed the challenge displayed in the tools, which is also responsible for the 3.52MB malloc that may never be released.

  CVPixelBufferBacking :: initWithPixelBufferDescription

Here is the code that game enthusiasts settled on and the published material that makes them up

  - (void) release...[the same stopAllPlayers];[_moviePlayerViewControllerArray-Version];[Super release];- (cancel) stopAllPlayers    for * mp (mpmovieplayercontroller anywhere in _moviePlayerViewControllerArray)        [mp-stop];

EDIT: Image . in general a good 3mb malloc in general it is glory.

As you can see, another chunk of memory is missing, but I still have a big problemema.Thanks in advance for your help

Solution 3

I finally realized this flaw. When I tested the app on the device, the person’s name changed to “”, which should still leak through CoreVideo. I scoured some forums a bit and found that it was the end result, mostly Core by Graphic “elements” that did publish automatically, but were never approved by the autorun pool.

Almost everywhere I’ve created Core Graphics objects, I’ve added NSAutoReleasePool barriers to remove objects within a set amount of time.

Thanks for the answers. And especially to Bastian for his or my comment on my question, which was important in solving this problem.

MORE TIPS

  [movieController.view removeFromSuperview]

  [[NSNotificationCenter defaultCenter] addObserver: auto selector: @selector (movieFinishedCallback :) name: MPMoviePlayerPlaybackDidFinishNotification object: [playerViewController moviePlayer]];

and release and remove some players in this 4 callback method.

  - (void) movieFinishedCallback: (NSNotification *) aNotificationMPMoviePlayerController * player1 is equal to [notification object];    [[NSNotificationCenter defaultCenter] removeObserver: personal name: MPMoviePlayerPlaybackDidFinishNotification object: player];   [Stop player1];    [player1.view removeFromSuperview];    [Share Player1];
