使用AVPlayer进行流式传输速度很慢 [英] Using AVPlayer for streaming is slow

问题描述

我使用AVPlayer从互联网上流式传输mp3文件，它的运行速度确实很慢.使用分析器发现，它首先下载整个文件，然后开始播放.有什么解决方法吗?

I use AVPlayer for streaming mp3 file from the internet and it works really slow. Using profiler I found out, that it downloads entire file at first, and then starts playing. Is there any workaround for this?

现在，我正在使用此代码

Right now, I'm using this code

if let player = player {
    NotificationCenter.default.removeObserver(self, name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

    let item = AVPlayerItem(url: url)

    player.replaceCurrentItem(with: item)
} else {
    player = AVPlayer(url: url)
}
player?.play()

我尝试过的事情:

• 将播放器?.play()移动到观察者，该观察者附加到该项目的 status 属性
• 使用属性 preferredForwardBufferDuration 和 preferredPeakBitRate

• move player?.play() to an observer, attached to status property of the item
• play around with properties preferredForwardBufferDuration and preferredPeakBitRate

一直以来，结果都是下载整个音频文件，然后才开始播放.

All the time the result is downloading a whole audio file and only then start of playing.

请注意，问题是-播放器仅在下载整个文件后才开始播放，而我希望它流mp3.

Please note, the issue is - player starts to play ONLY after the whole file was downloaded, while I want it to stream mp3.

推荐答案

要立即播放，您可以尝试设置

To play immediately you can try to set

player.automaticallyWaitsToMinimizeStalling = false
