    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 ...

  • 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.

  • How to get resolution label from a video in ffmpeg

    10 mai 2021, par HnnE

    My goal is to get the labels 1080p,720p,480p,360p,.. from the video using ffmpeg. Some videos doesn't have the correct dimension to it. for example : 854x546

    


    For the meantime I do it like this. 'height' + 'p' = 546p (which is wrong).
Should I check if 'height' > 480 then return 720 ?.

    


  • Merging four videos with different resolution in a Grid with ffmpeg

    5 juillet 2015, par Taufiq

    I want to marge four videos in to one as show below. I have achieve the correct output given all the videos have the same resolution. But I get an undesirable result with different resolution. See below for more details.

    i need ffmpeg code to get to merge 4 videos of different resolution in a grid format

    ffmpeg.exe -i "1.avi" -vf "[in] scale=iw:ih, pad=2*iw:ih [left];movie=2.avi, scale=iw:ih [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k "Output1.mp4"
    
ffmpeg.exe -i "3.avi" -vf "[in] scale=iw:ih, pad=2*iw:ih [left];movie=4.avi, scale=iw:ih [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k "Output2.mp4"
    
ffmpeg.exe -i "Output1.mp4" -vf "pad=iw:2*ih [top]; movie=Output2.mp4 [bottom]; [top][bottom] overlay=0:main_h/2" "Output_Stacked.mp4"

    Code above gives the follow output.

    For Example

    But the problem arises when I rotate one of the videos and merge them.

    Please tell me what I need to change to get the desired result. Thanks
