  • FFMPEG compand function does not work properly

    26 décembre 2020, par dereks

    This command limits the audio to -0.01dB :

    


    ffmpeg -y -i inp.wav -filter_complex "compand=0:0:-80/-80|-0.01/-0.01|20/-0.01" -c:a pcm_f64le out.wav


    


    But when I set attacks and decays it does nothing :

    


    ffmpeg -y -i inp.wav -filter_complex "compand=.1:.2:-80/-80|-0.01/-0.01|20/-0.01" -c:a pcm_f64le out.wav


    


    out.wav is the same as inp.wav.

    


    ffmpeg version 2020-12-24-git-9a0f5e412a-full_build-www.gyan.dev on Windows 10.

    here is my relevant .net application code

    &#xA;

      private async Task<mediametadata> GetVideoThumbnailAsync(IFormFile file,int frameTarget)&#xA;    {&#xA;     var fileName = file.FileName;&#xA;     var filePath = Path.Combine(_rootPath, "videos", fileName);&#xA;     var fileExtension = Path.GetExtension(filePath);&#xA;     &#xA;     // the xabe wrapper works with only mp4 extension to create thumbnail , if the file is any other format first convert it to&#xA;     //the mp4 format and then goahead with creating the thumbnail.  &#xA;     var thumbnailImageName = fileName.Replace(fileExtension, ".jpg");&#xA;     var thumbnailImagePath = Path.Combine(_rootPath, "thumbnails", thumbnailImageName);&#xA;     &#xA;            using (Stream fileStream = new FileStream(filePath, FileMode.Create)) {&#xA;                &#xA;             await file.CopyToAsync(fileStream);&#xA;            }&#xA;    Console.WriteLine(Path.Combine(_rootPath,"ffmpeg"));&#xA;    FFmpeg.SetExecutablesPath(Path.Combine(_rootPath,"ffmpeg"));&#xA;    IMediaInfo mediaInfo = await FFmpeg.GetMediaInfo(filePath);&#xA;    var videoDuration = mediaInfo.VideoStreams.First().Duration;&#xA;    IConversion conversion = await FFmpeg.Conversions.FromSnippet.Snapshot(filePath, thumbnailImagePath , TimeSpan.FromSeconds(frameTarget));&#xA;    IConversionResult result = await conversion.Start();&#xA;    MediaMetadata media = new MediaMetadata();&#xA;    media.DurationSeconds=Convert.ToInt32(videoDuration.TotalMilliseconds);&#xA;    // media.DurationSeconds=10;&#xA;    media.ThumbnailImagePath= thumbnailImagePath;&#xA;    return media;&#xA;    &#xA;    }&#xA;</mediametadata>
