我基于我的统一游戏里面的NAudio Demo modified for streaming a Shoutcast脚本工作。团结与n音讯RadioStreaming
我试图同时使用更新循环从MonoBehvaiour类删除原来，在我这个脚本流的时候，我只得到一些噪音，但不是音乐。
我通常会得到一个错误，而与格式
MmException相关执行：AcmNotPossible调用acmStreamConvert NAudio.MmException.Try（MmResult结果，System.String功能） NAudio.Wave.Compression.AcmStreamHeader .Convert（的Int32 bytesToConvert， System.Int32 & sourceBytesConverted） NAudio.Wave.Compression.AcmStream.Convert（的Int32 bytesToConvert， System.Int32 & sourceBytesConverted） NAudio.Wave.AcmMp3FrameDecompressor.DecompressFram Ë （NAudio.Wave.Mp3Frame框架，System.Byte [] DEST，的Int32 destOffset）
我与不同的无线电试图上网，但我总是得到这个错误。我不知道发生了什么...任何帮助吗？
