问题
I have an application where I play a video in the background, the process is very simple, the same behavior is repeated endlessly. On a user gesture the movie is played for a couple of seconds and paused, The application works perfectly as long as the suer didn't press the home button. when the application comes from the back-ground to the front-ground the video turns all black till the user makes a gesture.
In order to resolve the black screen problem, I shared the player object, then in AppDelegate.m < applicationDidBecomeActive > I prepare the player using the function
[sharedObj.player.moviePlayer prepareToPlay];
then I move its position to where is should be (because the player is returned to the starting point of the video at this time), to do so I call this function
[sharedObj.player.moviePlayer setCurrentPlaybackTime: whereItShouldBe];
And here comes my problem, the video isn't placed where it should be. there is a big difference between the "whereItShouldBe" time and "wherItIsCurrently".
I verified that it's the same object using the object identifier, so did anybody already faced a similar issue ? or has an idea to support me. Thanks in advance.
UPDATE
