Question

我正在尝试使用NReco.VideoConverter将.flac文件转换为.wav文件，但我一直收到错误，我不知道为什么。这是我用于转换的一段代码：

        //Create the NReco.VideoConverter.FFMpegConverter object
        var ffmpeg = new FFMpegConverter();

        //inputFile will be something like this:
        //type: string, "C:\\some\\folder\\fullTrackName" + ".flac"
        var inputFile = Path.Combine(downloadFolder + fullTrackNameNoExtension + ".flac");

        //outputFile will be something like this:
        //type: string, "C:\\some\\folder\\musicfile" + ".wav"
        var outputFile = Path.Combine(downloadFolder + fullTrackNameNoExtension + ".wav");

        //Convert the file using NReco.VideoConverter.FFMpegConverter
        ffmpeg.ConvertMedia(inputFile, outputFile, null);

inputFile / outputFile就像这样，这是我在插入断点并检查in / outputFile的值时看到的：

string，inputFile / outputFile：“Z：\\ Downloads \\ Audio - File（Original Mix）.flac”（或.wav）

这是我运行ffmpeg.ConvertMedia时收到的错误：

Answer 1

从“FFMpegConverter.EnsureFFMpegLibs”方法抛出异常，该方法在首次使用时提取ffmpeg二进制文件（默认为app bin文件夹），我可能会认为由于某种原因它被错误地确定（或者可能使用了网络路径）。 / p>

您可以尝试通过指定FFMpegConverter.FFMpegToolPath属性来更改ffmpeg.exe的位置（.net应该具有足够的权限来写入此文件夹）。

错误：使用NReco.VideoConverter
