  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
    Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.
    Modifier le thème graphique utilisé
    Pour modifier le thème graphique utilisé, il est nécessaire que le plugin zen-garden soit activé sur le site.

  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.

  • 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>
