How to convert audio in ogg format to amr

[AdorableParker]

I am trying to convert an audio file in ogg format to amr, but when i do it prompts me Exception in thread "main" ws.schild.jave.EncoderException: Exit code of ffmpeg encoding run is 1 This is what I did：

fun ogg2amr() {
    val cacheFile = File("speak.ogg")
    val target = File("input.amr")

    val audio = AudioAttributes()
    audio.setCodec("libvo_amrwbenc")

    val attrs = EncodingAttributes()
    attrs.setOutputFormat("amr")
    attrs.setAudioAttributes(audio)

    Encoder().encode(MultimediaObject(cacheFile), target, attrs)
}

The problem has been solved, the code is modified as follows：

fun ogg2amr() {
    val cacheFile = File("speak.ogg")
    val target = File("input.amr")

    val audio = AudioAttributes()
    audio.setCodec("libopencore_amrnb")
    audio.setChannels(1);
    audio.setSamplingRate(8000)

    val attrs = EncodingAttributes()
    attrs.setOutputFormat("amr")
    attrs.setAudioAttributes(audio)

    Encoder().encode(MultimediaObject(cacheFile), target, attrs)
}
