  • 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 (...)

  • FFMPEG hold multiple frames and use as a movie

    18 juin 2019, par Cole

    I have a video that I’m trying to create jump shots from. For example I want the output of my command to show frame 5 of the original clip for 30 frames, and frame 25 of the OG clip to show for 30 frames.

    assuming the OG clip is 30 FPS

    ffmpeg -t 1 -i og_clip.mp4 -filter_complex "
    
    [0]select=eq(n\,5)[H1];[0][H1]overlay[O1];
    
    [0]select=eq(n\,25)[H2];[0][H2]overlay[O2];
    
    [O1][O2]concat=n=2[Merge]" -map "[Merge]" out.mp4

    The above doesnt work right.

    What I’ve been doing up until now has been a two part command :

    ffmpeg -i og_clip.mp4 -vf "select=eq(n\,5)" -vframes 1 -y out_0.png
    
ffmpeg -i og_clip.mp4 -vf "select=eq(n\,25)" -vframes 1 -y out_1.png
    
ffmpeg -t 1 -i og_clip.mp4 -i out_0.png -i out_1.png -filter_complex "
    
    [0][1]overlay[H1];[0][2]overlay[H2];
    
    [H1][H2]concat=n=2[Merge]" -map "[Merge]" out.mp4

    Which has been working for me. The only problem is that the process of converting to a png first for each frame I want to use, takes too long. I’m trying to condense it all into one command. I figure that the encoding of the png is what takes so long.

    Any help would be much appreciated !
