  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • libdav1d : use film grain export flag to export AVFilmGrainParams side data

    12 novembre 2020, par Lynne
    libdav1d : use film grain export flag to export AVFilmGrainParams side data

    This patch is relatively straightforward with one exception :
    
the decoder option flag.
    
The option was introduced to troubleshoot but its existence is conflicting
    
and redundant now that we have a codec-generic flag.
    
Hence this patch deprecates it.
    

    The way it interacts with AV_CODEC_EXPORT_DATA_FILM_GRAIN is as follows :
    

    If filmgrain is unset and AV_CODEC_EXPORT_DATA_FILM_GRAIN is
    
present, disable film grain application and export side data.
    

    If filmgrain is set to 0, disable film grain and export side data.
    

    If filmgrain is set to 1, apply film grain but export side data if
    
the AV_CODEC_EXPORT_DATA_FILM_GRAIN flag is set. This may result in
    
double film grain application, but the user has requested it by setting
    
both.

  • FFmpeg film grain

    21 août 2019, par Some1Else

    I want to add a film grain effect using FFMPEG if possible.

    Taking a nice clean computer rendered scene and filter for a gritty black and white 16mm film look. As an example something like Clerks https://www.youtube.com/watch?v=Mlfn5n-E2WE

    According to Simulating TV noise Ishould be able to use the following filter

    -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)"

    but when I add it to my ffmpeg command

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y OUTPUT.AVI

    so the command is now

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)" OUTPUT.AVI

    I get the message

    Filtergraph ’format=yuv420p’ was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.
    - vf/-af/-filter and -filter_complex cannot be used together for the same stream.

    How can I change my ffmpeg command line so the grain filter works ? Additionally, can I add a slight blur too ? The old 16mm looks more like blurred then grainy.

    Thanks for any tips.
