iOS：AVQueuePlayer / AVPlayerItem'AVPlayerItem每次只能在播放器队列中占据一个位置。 [英] iOS: AVQueuePlayer/AVPlayerItem 'An AVPlayerItem can occupy only one position in a player's queue at a time.'

问题描述

我一直收到此错误：

'AVPlayerItem在
时间只能占用播放器队列中的一个位置。'

我NS登录球员项目，没有一个似乎是平等的。此外，我添加这只是为了确保：

  if（[player canInsertItem：itemToAdd afterItem：nil]）
 [player insertItem：itemToAdd afterItem：nil]; 
  

当我不确定是否可以工作（在不同的内存位置可以有两个相同的项目）我写了一个类别方法来测试一个播放器是否包含一个项目或与它相同的东西。

I keep getting this error:

'An AVPlayerItem can occupy only one position in a player's queue at a time.'

I NSLog'd the players items, and none of them seem to be equal. Further, I added this just to be sure:

if([player canInsertItem:itemToAdd afterItem:nil])
 [player insertItem:itemToAdd afterItem:nil];

When I wasn't sure if that would work (can have two identical items in different memory locations) I wrote a category method to test if a player contains an item or something identical to it. Yet, I'm still getting the error.

I've seen several posts of people getting this error with MPMoviePlayerController, but I'm not using that custom class, just the out of the box AVQueuePlayer.

Any ideas on how to fix this?
