  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • "Invalid or unexpected token" error when trying to execute ffmpeg build on lambda

    4 janvier 2019, par almarc

    I have a node.js script that uses ffmpeg to convert mp4 downloaded from YT to mp3 and save to Amazon S3. Uploading using the serverless framework. The "ffmpeg" file is included in the main directory (with .yml), downloaded from here :
    https://johnvansickle.com/ffmpeg/

    The code :

    'use strict'
    
process.env.PATH = process.env.PATH + ':/tmp/'
    
process.env['FFMPEG_PATH'] = '/tmp/ffmpeg';
    
const BIN_PATH = process.env['LAMBDA_TASK_ROOT']
    
process.env['PATH'] = process.env['PATH'] + ':' + BIN_PATH;
    

    
module.exports.download_mp3 = function (event, context, callback)
    
{
    
  require('child_process').exec('cp /var/task/ffmpeg /tmp/.; chmod 755 
    
  /tmp/ffmpeg;', function (error, stdout, stderr) {
    
  if (error) 
    
  {
    
    console.log('An error occured', error);
    
    callback(null, null)
    
  } 
    
  else 
    
  {
    
    var ffmpeg = require('ffmpeg');
    
    const aws = require('aws-sdk')
    
    const s3 = new aws.S3()
    
    const ytdl = require('ytdl-core');
    

    
    function uploadFromStream(s3) {
    
      const stream = require('stream')
    
      var pass = new stream.PassThrough();
    

    
      var params = {Bucket: "some-bucket", Key: "some-key", Body: pass};
    
      s3.upload(params, function(err, data) {
    
        console.log(err, data);
    
      });
    
      console.log("Should be finished")
    
      callback(null)
    
    }
    

    
    let stream = ytdl("some-video-id", {
    
      quality: 'highestaudio',
    
      filter: 'audioonly'
    
    });
    

    
    ffmpeg(stream)
    
      .audioBitrate(128)
    
      .format('mp3')
    
      .on('error', (err) => console.error(err))
    
      .pipe(uploadFromStream(s3), {
    
        end: true
    
    });
    
  }})
    
}

    When triggered, the function writes an error in logs :

    It’s, most definetely, an error in the "ffmpeg" file I’ve mentioned above (link provided). But I don’t know what’s the exact issue, I followed the first answer here : https://stackoverflow.com/questions/47882810/lambda-not-connecting-to-ffmpeg to include the ffmpeg build.

  • FFMPEG streaming ip cam get delay from start record to first frame

    4 janvier 2019, par Vincent Carretero

    I’m recording stream from IP CAM with FFMPEG.
    I would like to know the exact timestamp when start the output video.

    Example :
    I have an output mp4 file created at 2019/01/04 09:10:15 (file created).
    FFMpeg take few seconds to really start streaming (initialising, etc...)
    The first frame really start at 2019/01/04 09:10:19 (just supposed, I would like to get this info).

    Thanks !

  • Overlay a video on another video at specific time with FFmpeg

    4 janvier 2019, par Tina J

    I am trying to overlay a video with another video. I followed the original command OP posted here. And it works, but it overlays the video from time 0 :

    ffmpeg -i 720480.mp4 -i sdbug.mov -filter_complex "[0:0][1:0]overlay[out]" -shortest -map [out] -map 0:1 -pix_fmt yuv420p -c:a copy -c:v libx264 -crf 18  new.mp4

    I tried the correct answer to specify a time, but it is not working for me : 1) the overlay starts at around second 12, and 2) video is not played after the overlay is finished.

    ffmpeg -i 720480.mp4 -i sdbug.mov -filter_complex "[1:v]setpts=PTS+10/TB[a]; [0:v][a]overlay=enable=gte(t\,5):shortest=1[out]" -map [out] -map 0:a -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a copy new.mp4

    Anything changed recently on FFmpeg ?! Why isn’t it working ?

    Here is the output of this command (it finishes very fast) :
