App stuck in splash screen reload from background

January 21, 2013 - 11:31pm #1

Hi,

I am following VideoPlayback sample in Xcode. I almost developed my app is to just play videos on different marker and these video are also coming from webservice. Now I am stuck in just one problem is that when video is playing on marker at that time if pressed home button and apps goes in background and after when app resum it stuck on Splash screen, app working fine when no video is playing and it resume normally. When video is not playing then every function gets call successfully on app delegate but when video playing then No function call after going background like "applicationDidBecomeActive" and "applicationWillEnterForeground" it only stuck in splash screen and crash. I check device log it show me error "failed to resume in time".

Following What I am doing in Resign Active and become active function.

 

- (void)applicationDidBecomeActive:(UIApplication *)application

{

    NSLog(@"applicationDidBecomeActive");

       if (firstTime == NO)

    {

        [arParentViewController viewDidAppear:NO];

    }

    else {

        [self setupInfoScreen];

        // Start playback from the current position on the first run of the app

        for (int i = 0; i < NUM_VIDEO_TARGETS; ++i) {

            videoPlaybackTime[i] = VIDEO_PLAYBACK_CURRENT_POSITION;

        }

    }

       // Load the video for use with the EAGLView

    EAGLView* arView = [arParentViewController getARView];

    

#ifdef EXAMPLE_CODE_REMOTE_FILE

    // Load a remote file for playback

    for (int i = 0; i < NUM_VIDEO_TARGETS; ++i) {

        VideoPlayerHelper* player = [arView getVideoPlayerHelper:i];

        [player load:@"http://<SOME_URL>" playImmediately:NO fromPosition:VIDEO_PLAYBACK_CURRENT_POSITION];

    }

#else

    // For each video-augmented target

    for (int i = 0; i < NUM_VIDEO_TARGETS; ++i) {

        VideoPlayerHelper* player = [arView getVideoPlayerHelper:i];

        NSString* filename;

        

        switch (i) {

            case 0:

                filename = @"Alan!.mp4";

                break;

          }

        

        if (NO == [player load:filename playImmediately:NO fromPosition:videoPlaybackTime[i]]) {

            NSLog(@"Failed to load media");

        }

    }

#endif

    firstTime = NO;

}

 

- (void)applicationWillResignActive:(UIApplication *)application

{

    // Remove the native movie player view (if it is displayed).  This gives us

    // a clean restart on iOS 4 and 5

    NSLog(@"applicationWillResignActive");

    [arParentViewController removeMoviePlayerView];

       EAGLView* arView = [arParentViewController getARView];

  for (int i = 0; i < NUM_VIDEO_TARGETS; ++i) {

        VideoPlayerHelper* player = [arView getVideoPlayerHelper:i];

            // If the video is playing, pause it and store the index of the player

        // so playback can be resumed

        if (PLAYING == [player getStatus]) {

            [player pause];

            NSLog(@"Player has been paused");

        }

        // the player is currently paused)

        videoPlaybackTime[i] = [player getCurrentPosition];

        

        // Unload the video

        if (NO == [player unload]) {

            NSLog(@"Failed to unload media");

        }

    }

    // do the same as when the view has dissappeared

     [arParentViewController viewDidDisappear:NO];

     // Remove the info screen (if it's displayed)

    [infoView removeFromSuperview];

}

Hi Aleem,

Can I just check that if you are using a web service then the Video is playing full screen, as it's from a URL right?

I have tried the video playback sample on iOS5 and iOS6 to try and reproduce by forcing the app to play fullscreen.

iOS5 is fine, whereas iOS6 it seems to return to a black screen rather than the splash screen/crash as you are stating - could you confirm what you are seeing and on what device/iOS i.e. is it only iOS6?

Finally, if you are seeing something different to me can you create a project based on the Video Playback sample and PM me a link so I can download and investigate further?

Thanks,

N
