  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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.

  • Showing in-video visual progress bar with FFMPEG ?

    20 mai 2024, par Taapo

    As OBS Studio lacks a visual indicator to show how far a video has progressed (and when you need to advance to the next scene), I was wondering if there is a command-line option (or solution) to get FFMPEG to re-encode the video and show a progress bar at the bottom of the video that shows how long the video has been playing so far.

    


    Is there such a feature ?

    


  • FileNotFoundError on aws Lambda when concatenating videos with ffmpeg

    2 juillet 2021, par Shibu Menon

    Goal :

    



      

    • Concat 2 videos (both are in an s3 bucket) via aws Lambda using ffmpeg

      • 


    • Upload the resultant output.mp4 to another S3 bucket

      • 


    • Python 3+

      • 


    



    I've already created a layer containing a static ffmpeg

    



    The Error :

    



    {
  "errorMessage": "[Errno 2] No such file or directory: '/tmp/output.mp4'",
  "errorType": "FileNotFoundError",
  "stackTrace": [
    [
      "/var/task/lambda_function.py",
      19,
      "lambda_handler",
      "s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))"
    ]
  ]
}


    



    My Lambda function :

    



    import json
import os
import subprocess
import boto3

s3 = boto3.resource('s3')
bucketLowRes = s3.Bucket("bucket-conc-lowres")

def lambda_handler(event, context):
    # TODO implement

    mp4OutputFileName = 'output.mp4'

    new_file_key = os.path.abspath(os.path.join(os.sep, 'tmp', mp4OutputFileName))
    subprocess.call( ['/opt/ffmpeg', '-i', 'concat:s3://bucket-word-clips/00th76kqwfs915hbixycb77y9v3riwsj30.mp4|s3://bucket-word-clips/00uoakp6jyafbu13ycvl6w2i9tj42eux30.mp4', new_file_key ] )

    s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))

    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }


    



    Question :

    



      

    • FileNotFoundError : Where is the output mp4 file of my ffmpeg concat being saved ??

      • 


    • And if it is being saved to /tmp/output.mp4 , then why the FileNotFoundError ??

      • 


    



    thanks

    


  • FFMPEG : same audio stream required in 2 output files [on hold]

    5 novembre 2016, par dosdan

    I want to take an input AVI file with one video stream and one PCM audio stream and produce two AVC output files, with different scalings (1024:768 and 640:480), but with the same AAC audio stream in each of them. How do I map this so both output files will contain an AAC stream as well as their respective video resized steam ? As I’ve got it doing now, the 2nd file has no audio.

    Dan.
