  • 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 How does the blend filter work

    8 juin 2018, par tainguyen

    I have small project which uses blend filter of FFmpeg library.

    I read the examples of this document
    https://ffmpeg.org/ffmpeg-filters.html#blend_002c-tblend

    But I’m not clearly understand about it.

    X, Y : the coordinates of the current sample

    W, H : the width and height of currently filtered plane

    What are the sample and filtered plane ?
    Is there any document about these things.

  • h264 : make slice threading work with deblocking_filter=1

    h264 : make slice threading work with deblocking_filter=1

    In such a case, decode the MBs in parallel without the loop filter, then
    
execute the filter serially.
    

    The ref2frm array was previously moved to H264SliceContext. That was
    
incorrect, since it applies to all the slices and should properly be in
    
H264Context (it did not actually break decoding, since this distinction
    
only becomes relevant with slice threading and deblocking_filter=1,
    
which was not implemented before this commit). The ref2frm array is thus
    
moved back to H264Context.

  • Concatenation of files using ffmpeg does not work as I expected. Why ?

    19 décembre 2018, par Peter Olson

    I execute the following command line

    ffmpeg.exe
    
    -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi 
    
    -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi 
    
    -i C:\Beema\temp\9016730-51056331-stitcheds.avi  
    
    -i C:\Beema\video-source\GOTTA_BEEMA176x144short.avi 
    
    -y -ac 1 -r 24 -b 25K 
    
    C:\Beema\video-out\9a062fb6-d448-48fe-b006-a85d51adf8a1.mpg

    The output file in video-out ends up having a single copy of DO_U_BEEMA. I do not understand why ffmpeg is not concatenating.

    Any help is dramatically appreciated,
