英文:
AudioFileIO leaves inputstream opened after giving log warn "No space to find another frame"
问题
我试图在Java中使用以下代码读取文件的音频长度：
return AudioFileIO.read(new File(audio)).getAudioHeader().getTrackLength() * 1000;
这能够工作并给我（大致）音频文件的长度，但会保持一个输入流打开，意味着稍后我无法删除文件，至少不能在运行时删除。这是个问题，因为我在这里使用临时文件，需要清理目录。
这是我在控制台上得到的输出：
Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.AbstractID3v2Frame readIdentifier
WARNING: tmp0.mp3:No space to find another frame:
Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.ID3v24Tag readFrames
WARNING: tmp0.mp3:Invalid Frame:tmp0.mp3:No space to find another frame
Mai 06, 2023 10:30:13 PM org.jaudiotagger.audio.mp3.MP3File readV2Tag
SEVERE: Could not invoke DirectBuffer method - illegal access
这是文件的元数据，根据（https://www.checkfiletype.com）：
文件大小 36 kB
文件类型 MP3
文件类型扩展 mp3
MIME类型 audio/mpeg
ID3大小 45
MPEG音频版本 2
音频层 3
音频比特率 128 kbps
采样率 24000
通道模式 单声道
MS立体声 关闭
强度立体声 关闭
版权标志 否
原始媒体 是
强调 无
编码器设置 Lavf58.76.100
持续时间 2.30秒（约）
我似乎无法完全理解导致它抛出警告的问题。元数据有问题吗？如果是这样，我该如何修复？我是通过API获取.mp3的。是否有其他类我可以使用？AudioSystem/AudioInputStream类也不起作用，并抛出错误，说文件类型不受支持。
提前感谢！

I am attempting to read a files audio length in Java using the following code:
return AudioFileIO.read(new File(audio)).getAudioHeader().getTrackLength() * 1000;
This works and gives me (roughly) the length of the audio file, but leaves an inputstream open, meaning that later on I cant delete the files, atleast not during runtime.
This is problematic because Im using temporary files here and the directory needs to be cleared.
This is the output I get in my console:
Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.AbstractID3v2Frame readIdentifier
WARNING: tmp0.mp3:No space to find another frame:
Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.ID3v24Tag readFrames
WARNING: tmp0.mp3:Invalid Frame:tmp0.mp3:No space to find another frame
Mai 06, 2023 10:30:13 PM org.jaudiotagger.audio.mp3.MP3File readV2Tag
SEVERE: Could not invoke DirectBuffer method - illegal access`
This is the files metadata, according to (https://www.checkfiletype.com):
File Size 36 kB
File Type MP3
File Type Extension mp3
MIME Type audio/mpeg
ID3 Size 45
MPEG Audio Version 2
Audio Layer 3
Audio Bitrate 128 kbps
Sample Rate 24000
Channel Mode Single Channel
MS Stereo Off
Intensity Stereo Off
Copyright Flag False
Original Media True
Emphasis None
Encoder Settings Lavf58.76.100
Duration 2.30 s (approx)
I cant entirely seem to understand what the problem is thats making it throw that warning. Is the metadata faulty? If so, what can I do to fix it? Im getting the .mp3 through an API.
Is there a different class I could use? The AudioSystem/AudioInputStream classes didnt work either and threw an error, saying the file type is unsupported.
Thanks in advance!
