  • Monitoring de fermes de MediaSPIP (et de SPIP tant qu’à faire)

    31 mai 2013, par

    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.
    Description des scripts

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmgep stucks while merging two streams at input 0 [closed]

    3 février 2024, par Robi Tagore

    I tried to merge two streams downloaded before, I was using ffmpeg to combine them. I could use the path directly, but I felt it would'nt always be, so I read the steams, after I combine them,
everytime I run the code it std errs the following output, and creates merged.mp4 with 0 bytes, help me find the mistake

    


    code

    


    
const {spawn} = require("child_process");
const fs = require("fs")


var audio = fs.createReadStream("audio.aac")
var video = fs.createReadStream("video.mp4")



var ffprocess = spawn("ffmpeg",[
    '-y',
    '-i', 'pipe:0', 
    '-i', 'pipe:1',  
    '-c', 'copy',  
    '-f', 'mp4',    
    'pipe:2',   
])

video.pipe(ffprocess.stdin)
audio.pipe(ffprocess.stdin)


ffprocess.stdout.on("data")


ffprocess.stderr.on("data", (data) => {
    console.log(`ffmpeg stderr ${data}`);
});
  
ffprocess.on("close", (code) => {
if (code === 0) {
    console.log("FFmpeg process exited successfully");
} else {
    console.error(`FFmpeg process exited with code ${code}`);
}
});
