AVPlayer无法播放FFMPEG的音频文件

在请求音频数据之前，AVPlayer向FFMPEG请求字节范围0-1。

FFMPEG给出200响应，但AVPlayer要求206响应。

这将导致请求失败，并且无法播放音频。

预期行为：通过ffmpeg流播放曲目

当前行为：尝试使用ffmpeg流式传输时，我们收到“操作已停止”

样本FFMPEG命令：

ffmpeg -i "/path/to/audio/track.mp3" -vn -strict -2 -acodec pcm_u8 -f wav -listen 1 -seekable 1 http://localhost:8090/restream.wav

玩家记录：

Error Domain=AVFoundationErrorDomain Code=-11850 "Operation Stopped" UserInfo={NSLocalizedFailureReason=The server is not correctly configured., NSLocalizedDescription=Operation Stopped, NSUnderlyingError=0x600003bcc4b0 {Error Domain=NSOSStatusErrorDomain Code=-12939 "(null)"}}

!Error writing trailer of http://localhost:8090/restream.wav: Broken pipe

Apple将此错误定义为：

+"The HTTP server sending the media resource is not configured as expected. This might mean that the server does not support byte range requests."

并在此StackOverflow帖子中总结得很好：

when AVPlayerItem receive a video URL , it do the following task:

    Send a bytes request HTTP Request, and range = 0 -1
    If the response code is 206 and return 1 bytes data, It do the 3th task, if not, AVErrorServerIncorrectlyConfigured error occurred.
    continue send other HTTP Request, to download segment of All duration. and the response of VideoData code must be 206

In my situation , when send range[0-1] HTTP request, the server side give me a 200 OK response, So error occurred.

使用此示例应用程序进行重现：

也可以使用标准ffmpeg将URL复制到本地或远程ffmpeg URL中来复制

我们可以通过更改FFMPEG或AVPlayer来解决此问题吗？
