  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Emballe médias : à quoi cela sert ?

    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.

  • Is there any way to distinguish a completely unedited Shadowplay recording from a recording meant to imitate a Shadowplay recording via FFMpeg ? [closed]

    24 octobre 2020, par paqoe

    I'd first like to preface this by saying that I have essentially no experience with programming or coding, so if this is a stupid question then just disregard it lol.

    


    I help to manage runs for a speedrunning website, and as people have gotten better at hacking & faking their runs, it's gotten increasingly difficult to tell the difference, and sometimes even impossible. As a result, the best solution I can come up with is to take a close look at the metadata of their (if legitimate) unedited raw footage using various metadata viewers.

    


    The only issue with this, however, is that as far as I can tell, there's pretty much no way to tell between a real unedited Shadowplay recording and an edited FFmpeg recording as far as I can tell. So, my question is, is there actually any possible way to tell the difference ? I have no clue how metadata works or how feasible this is, but it would make it nearly impossible to fabricate recordings if it's possible to always discern an FFmpeg recording from a Shadowplay recording, so I'm looking for pretty much any possible solution here.

    


  • drop related audio when dropping video frames

    24 août 2022, par Silentfury

    I have an ffmpeg complex filter that drops frames using mpdecimate (so there is no predictable rate of dropping). The video part works fine and as intended. I use SETPTS to adjust the timesstamps of the not dropped frames to get a smooth video without duplicates.

    


    Now I want to drop the related audio in parallel, but I utterly fail.

    


    I need the audio frames related to the droped video frames to be dropped as well, while keeping the audio related to the not-dropped video frames.

    


    I have tried to replace SETPTS with '-vsync vfr' but that keeps all audio (decorated with still video parts). I have also tried to use ASETPTS but have no clue how to apply it to my case.

    


    Is there a way to drop the AUDIO parts in parallel to the dropped VIDEO parts ?

    


    Thanks a lot for your support !

    


  • FFMPEG scaling watermark

    27 mai 2020, par razz

    I'm currently using a command to add a watermark + scrolling text and some extra encoding options to a video.

    



    The watermark + scrolling text are made to fit correctly when the video is 1280px (width) but when the original video is any other size (for example 1920px) the watermark + scrolling text gets tiny so i need to scale this.

    



    watermark size= 400x48

    



    Current code i'm using

    



    -i logo.png -filter_complex "[0:v][1:v] overlay=x=(main_w-overlay_w):y=(main_h-overlay_h-4)[out];[out]drawtext=fontsize=20:font=tahoma:alpha=0.5:fontcolor=white:borderw=0.8:bordercolor=black:text=THIS IS MY SCROLLING TEXT :y=line_h-4:x=w-(t-300)*w/40" -keyint_min 20 -vcodec libx264 -c:a copy -b:v 1700k -movflags +faststart

    



    I think that this piece of code scale2ref=400*iw/1280:48*iw/1280 might do the work but i have no clue where exactly to paste this in. I keep on getting errors.
