  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Bluebird promise, promise.each only executes once

    20 mars 2017, par kenpeter

    There is a function called musicPromise(). What this function does is

    1. It gets all mp4 files and loop through it.
    2. then it tries to convert each mp4 to mp3, using fluent-ffmpeg

    The problem I am facing is

    1. It only converts 1 file, no matter how many mp4 files I have.

    2. And it seems never reach to proc.on('end', (x) => {

    Full code here :

    // search
    
const glob = require('glob');
    
// wait for
    
const Promise = require('bluebird');
    
// fs
    
const fs = require('fs');
    
// mp3
    
const ffmpeg = require('fluent-ffmpeg');
    

    
// video source file path
    
const videoPath = '/home/kenpeter/Videos/4K\ Video\ Downloader';
    

    
// audio source file path
    
const audioPath = __dirname + "/audio";
    

    
// child process, exec
    
const exec = require('child_process').exec;
    

    
// now rename promise

          let tmpFileName = lastElement.replace(/[&amp;\/\\#,+()$~%'":*?&lt;>{}\ ]/g, "_");

-i /path/to/audio.mp3 -vsync vfr -vf scale="640:640" -pix_fmt yuv420p \
    
/path/to/output.mp4 2>&amp;1

    The detail contents of text.txt
