  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Why convert wav to mp3 get different length

    13 avril 2022, par sybil

    I use NAudio and NAudio.Lame to convert a wav file to mp3 file,code like that :

    


    using var reader = new WaveFileReader(file);
using var ms = new MemoryStream();
var writer = new LameMP3FileWriter(ms, reader.WaveFormat, 32);
reader.CopyTo(writer);
writer.Flush();
File.WriteAllBytes(file.Replace("wav", "mp3"), ms.ToArray());


    


    the wav file length is 1500ms,but the mp3 file length is 1557ms.

    


    And I do the same thing by using ffmpeg.exe,command like that :

    


    ffmpeg -i c:\2\xxx.wav c:\2\xxx.mp3


    


    the output info :

    pgssubdec : fix subpicture output colorspace and range

    Functionality used before didn’t widen the values from limited to
    
full range. Additionally, now the decoder uses BT.709 where it
    
should be used according to the video resolution.
    

    Default for not yet set colorimetry is BT.709 due to most observed
    
HDMV content being HD.
    

    BT.709 coefficients were gathered from the first two parts of BT.709
    
to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2).
    
They were additionally confirmed by manually calculating values.
    

    Fixes #4637
