scala - .wav 到 .mp3 文件的转换在带有 JAVE2 库的服务器上不起作用

Question

import java.io.File
import ws.schild.jave.{Encoder, MultimediaObject}
import ws.schild.jave.encode.AudioAttributes
import ws.schild.jave.encode.EncodingAttributes


object MP3ConversionUtil {
  private val codec = "libmp3lame"
  private val bitRate = 32000
  private val samplingRate = 44100
  private val channel = 2
  val toMP3: (File => File) = (file) => {
    val source = file
    val targetMP3 = new File(s"${file.getAbsolutePath.replace(".", "")}.mp3")

    val audio = new AudioAttributes
    audio.setCodec(codec)
    audio.setBitRate(bitRate)
    audio.setSamplingRate(samplingRate)
    audio.setChannels(channel)

    val attrs = new EncodingAttributes
    attrs.setAudioAttributes(audio)
    attrs.setOutputFormat("mp3")

    val instance = new Encoder()
    instance.encode(new MultimediaObject(source), targetMP3, attrs, null)
    targetMP3
  }
}

上面的代码工作正常，可以完美地转换为 mp3。 在 linux(rehl-Linux x86_64) 服务器中，它不工作，抛出错误 ws.schild.jave.InputFormatException。
