  • Monitoring de fermes de MediaSPIP (et de SPIP tant qu’à faire)

    31 mai 2013, par

    Lorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
    Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.
    Description des scripts
    Trois scripts Munin ont été développés :
    1. mediaspip_medias
    Un script de (...)

  • Output file not specified [closed]

    16 mai 2024, par Rich Madrid

    I have been messing around with ffmpeg working on basic mkv to mp4 conversions the last couple of days on my Mac and Windows computers. Mac was easier buy my windows desktop has a much faster OS so I wanted to do some conversions on it tonight. Got ffmpeg installed and working.

    


    After having some issues with the command prompt not finding the directory, I solved that with the following basic code to convert an mkv file to an mp4 for me :

    


    ffmpeg -i "C:\Users\Computer\videos\decade.mkv" "C:\Users\Computer\Videos\RJ videos\Complete\decade.mp4"


    


    I moved on to wanting to scale up an mkv to 1080p and use a yadif filter. I couldn’t find an adequate way to do this so I used a portion of the command that worked on my Mac last night, and stuffed it into the command for windows and I got an error code “at least one output file must be specified” after using the following command :

    


    ffmpeg -i "C:\Users\Computer\videos\decade.mkv" -vf "yadif=1,scale=1440x1080:flags=lanczos,setsar=1" -c:v libx264 -crf 21
-c:a aac -b:a 128k -ar 48k "C:\Users\Computer\Videos\RJ videos\Complete\decade.mp4"


    


    What am I doing wrong ?

    


  • sh4 : remove architecture

    7 juin 2024, par Rémi Denis-Courmont
    sh4 : remove architecture

    Support for SuperH was dropped over a decade ago. There no longer is any
    
architecture-specific code to be found, so just remove the corresponding
    
test. Technically it is still possible to compile FFmpeg as the
    
"generic" (pure C) architecture.

  • avfilter/scale* : add option reset_sar

    31 janvier, par Gyan Doshi
    avfilter/scale* : add option reset_sar

    For anamorphic videos, enabling this option leads to adjustment of
    
output dimensions to obtain square pixels when the user requests
    
proportional scaling through either of the w/h expressions or
    
force_original_aspect_ratio.
    

    Output SAR is always reset to 1.
    

    Option added to scale, scale_cuda, scale_npp & scale_vaapi.
    

    libplacebo already has a similar option with different semantics,
    
scale_vt and scale_vulkan don't implement force_oar, so for these
    
three filters, I've made minimal changes needed to not break building
    
or change output.
