  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Image files as inputs with AWS Elastic Transcoder ?

    7 décembre 2017, par Geuis

    Here’s my situation. I’ve been working on building a service at work that takes dynamically generated images and outputs animations as mp4 or gif. The user has the options of setting dimensions, time for each frame, etc.

    I have this working currently with ffmpeg. It works ok, but is difficult (and potentially expensive) to scale due largely to the cpu/memory requirements that ffmpeg needs.

    I just spent some time experimenting with AWS’s Elastic Transcoder. It doesn’t seem to like static image files (jpg, png) as source material in jobs. The file types aren’t listed under the available Preset options either.

    I’m sure that I could adapt the existing architecture to save the static images as video files (sound isn’t needed) and upload those. That will still require ffmpeg to be in the pipeline though.

    Are there any other AWS services that might work with my needs and allow the use of Elastic Transcoder ?

  • Stream mp4 file with watermark through a web using ffmpeg

    24 mars 2023, par Jose A. Matarán

    I'm having problems with ffmpeg, probably due to my inexperience with this software.

    


    My basic need is the following : I have a series of videos with material that I want to protect so that it is not plagiarized. For this I want to add a watermark so that when a user views it, they also see some personal data that prevents them from downloading and sharing it without permission.

    


    What I would like is to create a small Angular + Java application that does this task (invoking ffmpeg via Runtime#exec)

    


    I have seen that from ffmpeg I can emit to a server, like ffserver but I wonder if there is a somewhat simpler way. Something like launching the ffmpeg command from my java application with the necessary configuration and having ffmpeg emit the video along with the watermark through some port/protocol.

    


    EDIT

    


    I have continued to investigate and I have seen that ffmpeg allows you to broadcast for WebRTC, but you need an adapter. What I would like and I don't know if it is possible is to launch ffmpeg so that it acts as a server and it can be consumed from the web.

    


  • Improve LPC order guess

    3 décembre 2014, par Martijn van Beurden
    Improve LPC order guess

    The recent compression preset retuning improved upon most material
    
but it the few tracks that show regression are usually classical
    
music. This patch improves compression by improving the LPC order
    
guess, of which classical music benefits most.
    

    Improvement is 0.007% on average but up to 0.1%. I haven’t seen
    
regressions for any of my test samples.
