  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Audio fade in and looping

    30 juin 2020, par BIOStheZerg

    I'm trying to put some background music to a video with a person speaking. The background music should face in over a few seconds. The music is a short snippet, which loops really well. I tried to loop it via ffmpeg so that I have everything in one command :

    


    ffmpeg -i video_file.mp4 -f lavfi -i amovie=audio_file.wav:loop=0 -filter_complex '[0:a] volume=2.0 [voice]; [1:a] afade=in:st=0:d=5, volume=0.1 [soundtrack]; [voice][soundtrack] amix=inputs=2:duration=shortest' -codec:v copy out_file.mp4


    


    (this is a simplified version, the real one has a side chain compress as well, but that's irrelevant)

    


    The thing that doesn't work for me is the combination of the looping and the afade filter - every iteration of the background music fades in on its own. How could I do this such that only the first one fades in and the others just "continue" playing ? Is it possible to do it in a single command ?

    


    I know I could pre-loop a certain number of iterations based on the video length, but that would require creating a possibly large file (or lose audio quality via compression).

    


    Thanks !

    


  • Convert WAV to FLAC or ALAC whilst preserving/converting id3 tags [closed]

    28 mars 2023, par Jai_1008

    Basically I want to render my mastered audio out of Wavelab, (the industry standard for mastering music) and then be able to have my track added to the macOS Music app with all metadata already included.

    


    It's more complicated than this, but basically Wavelab only gives serious metadata options to its WAV output. If I render out as FLAC, which, as a format, has better metadata implementation than WAV files, the metadata options I have avialable in Wavelab are not as good/extensive.

    


    So to get the metadata I want, I have to render as WAV. But then I can't put that in Apple Music app whilst keeping it's id3 tags. All the fields like Artist etc are blank in the Music app.

    


    The Music app DOES recognise the metadata from an ALAC file. So I have to convert a WAV to ALAC (or FLAC as converting FLAC to ALAC is easy) whilst somehow preserving its metadata. And for the life of me, I cannot find an answer to this from searching and reading everything.

    


    Any help ? I was looking into ffmpeg as an option, but no one speaks to this specific situation of mine. Converting WAV to FLAC or ALAC and preserving the WAVs metadata (id3 tags).

    


    I've tried using -map_metadata 0 when converting a WAV to FLAC in ffmpeg, but ffmpeg says it's ignoring ID3 tags because it found more suitable metadata. But the resulting FLAC only has Artist and copyright fields included in its metadata.

    


  • How to control bitrate (by time) of MP3 - different CBR/VBR in different sections ?

    8 juillet 2023, par user8223842

    I have a audio file several hours in length which is 85% talking, and 15% music.
I want the talking to have a VBR 64 kbps - and the music to be 256 kbps.
Setting just 1 VBR across the file doesn't work so well, I'd rather do it manually and say "I want these parts to have this bitrate, and these others to have a different one".
Is this possible ? And if not with mp3, with another format ?
Thanks++
