  • 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 (...)

  • Is ffmpeg running in CPU or GPU ?

    25 mai 2021, par Raghul Selvaraj

    Step 2 : CPU vs GPU

    


    



    that if the CPU % is more than 90 then the app is running in CPU.

    



    While configuring ffmpeg, I enabled opencl. ffmpeg configurations are,

    



    ffmpeg version ebe0fa0 Copyright (c) 2000-2015 the FFmpeg developers
  built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-4)
  configuration: --enable-gpl --enable-libx264 --enable-opencl --enable-nonfree --enable-libmfx --enable-libmp3lame --enable-libaacplus

Hyper fast Audio and Video encoder

    But while running ffmpeg using the command

    



    ffmpeg -i /home/M.mp4 -c:v h264 -preset:v faster /home/out.avi

    



    the CPU% has been more than 90 (375%).

    



    In case of ImageMagick, if I enable opencl while configuring, then the app will run in GPU, i.e., the CPU% will be less than 90. I noticed that.

    



    But in case of ffmpeg, it is GPU accelerated one. Then, Why the CPU% is more than 90% ? Is the ffmpeg running in CPU or GPU ? If it is not, how can I make it to run in GPU ?

    


  • what is the best way to append a video file to multiple video files using batch file [on hold]

    5 avril 2017, par JAGGADAKU

    i am beginner with computer programming and i have knowledge of c/c++

    from [https://trac.ffmpeg.org/wiki/Concatenate][1] i have learned that how to merge video files using ffmpeg

    To list all video files containing in a folder

    (for %%i in (*.mp4) do @echo %%i) > mylist.txt

    to concatenate files

    ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4

    This merges all files of a list to one single file.
    but How do i append one video file(main.mp4) at the starting of all the video files listed in mylist.txt ?

    can someone help me ?

    Hello there

    i have tried following code i don’t know what’s wrong with it but it is not `

    @echo off
    
(for %%i in (*.mp4) do @echo %%i) > mylist.txt

    echo %%A
    
    ffmpeg -i "concat:main.mp4|%%A" -c copy  %%Aoutput.mp4
    

    
)

  • Make an Alpha Mask video from PNG files

    15 juin 2019, par Archimedes Trajano

    For RenPy it uses the notion of an Alpha Mask video https://www.renpy.org/doc/html/movie.html#movie-displayables-and-movie-sprites

    I can convert the a bunch of PNGs with alpha channel to http://wiki.webmproject.org/howtos/convert-png-frames-to-webm-video I was wondering how to do the same sort of thing without creating another set of PNG files with just the alpha frame.

    I’ll be okay with something that uses imagemagik in the middle if needed.
