Installation en mode ferme
4 février 2011, parLe 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 (...) -

Calculate edits in QuickTime Movie File with Edit List Atom
8 juin 2016, par kodonnellIn a Linux environment, is there a way to calculate any edits in a QuickTime Movie File track ? Specifically, I need duration and start time of edits in relation to the movie.
I have been parsing the raw mov file to look at the Edit List Atom ( i.e. ’elst’ ) to get the track duration and media time but, even after the adjustments for time scale units the start time always seems off.
For example, I have a single track video which has been edited to have first and last 6 seconds of the video removed. However, when I look at the ’elst’ atom of that file the track duration is the length of the new file but, the media time does not match what I would have expected (i.e. something equivalent to 6 seconds).
I have tried looking into tools like FFmpeg but have had little success.

JAAD exception "movie box at end of file"
12 avril 2023, par B. StackhouseI'm using JAAD (Java Advanced Audio Decoder) version 0.8.4, and m4a songs imported by the iTunes player from a CD play correctly. Any mp3 songs converted by ffmpeg to m4a results in an JAAD error during the following statement. I have seen this question before, but never any solution. What do I need to do ?


for example :


ffmpeg -i input.mp3 -vn -c:a aac -b:a 192k output.m4a 

final AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(songFile.toURI().toURL());

net.sourceforge.jaad.mp4.MP4Exception: movie box at end of file, need random access
