AVPlayer失败，出现AVPlayerItemStatusFailed(OSStatus错误-12983) [英] AVPlayer fails with AVPlayerItemStatusFailed (OSStatus error -12983)

问题描述

有时AVPlayer失败，并显示AVPlayerItemStatusFailed，发生该故障后，AVPlayer继续失败，并显示AVPlayerItemStatusFailed.我试图清除AVPlayer实例并创建一个新实例，但无法解决的问题.同样，具有AVPlayer实例的removingFromSuperview UIView并使用AVPlayer初始化新项目也不能解决问题.

Sometimes AVPlayer fails with AVPlayerItemStatusFailed and after that failure occurred, AVPlayer continues to failed with AVPlayerItemStatusFailed. I tried to clear the AVPlayer instance and create new one, but I cannot achieve AVPlayerItemStatusFailed failure to solve. Also removingFromSuperview UIView with AVPlayer instance and initializing new item with AVPlayer does not solve the problem.

所以我发现无法完全清除AVPlayer.是否有人建议您尝试完全清除AVPlayer并使其在故障后起作用?

So I figured that out AVPlayer couldn't been cleared completely. Is there anybody suggest anything to try for clearing the AVPlayer completely and make it works after failure?

UPD. 对于@matt

playerItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:filePath.path]];

if (!self.avPlayer) {
  avPlayer = [AVPlayer playerWithPlayerItem:playerItem];
}

[avPlayer.currentItem addObserver:self forKeyPath:@"status" options:0 context:nil];

if (self.avPlayer.currentItem != self.playerItem) {
  [self.avPlayer replaceCurrentItemWithPlayerItem:playerItem];
}

AVPlayerLayer *avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayer];
avPlayerLayer.frame = self.bounds;
[self.layer addSublayer:avPlayerLayer];

avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;

[avPlayer play];

推荐答案

问题是此行是无条件的:

The problem is that this line is unconditional:

[self.layer addSublayer:avPlayerLayer];

因此您每次都添加一个新的播放器层.因此，您要堆积许多播放器图层.这是错误的.只能有一个.保留对旧播放器层的引用，并在添加播放器层之前将其删除，或者，如果该播放器与以前的播放器相同，并且在界面中已经具有关联的播放器层，则不执行任何操作.

Thus you are adding a new player layer every time. Thus you are piling up many player layers. This is wrong. There must be only one. Keep a reference to the old player layer and remove it before adding a player layer, or, if this is the same player as before and it has the associated player layer in the interface already, do nothing.
