    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

    15 septembre 2021, par Welborn Machado

    Chroma Key Image

    



    I want to replace green color of the above chromekey image with another image. The image should only replace with the green color not overlay entire image.

    



    I am using following sample command below but it overlay the entire image not only the green color.

    



    -y -i /storage/emulated/0/dummyResized.jpg -i /storage/emulated/0/circularImage.png -filter_complex [1:v]colorkey=green:0.3:0.2[ckout] ;[0:v][ckout]overlay[out] -map [out] /storage/emulated/0/outputBlackCircular.jpg

    


  • How do I apply a complex filter to audio only in fluent-ffmpeg ?

    4 juin 2020, par billy61300

    I want to apply a filter to audio only and keep the video intact. fluent-ffmpeg applies the filter to audio but removes the video afterwords. What would I do to keep the video from being removed afterwords ?

    



    Here's my current complexFilter command :

    



    .complexFilter([
    {
        filter: "acrusher",
        options: {
            level_in: .1,
            level_out: 1,
            bits: 64,
            mix: 0,
            mode: "log"
        },
        outputs: "output"
    }
], "output")


    


  • How to get FFmpeg to consistently apply speed effect to first few frames ?

    16 janvier 2021, par melody_florum

    I am using FFmpeg to apply speed effects to short gifs and videos and I noticed strange stuttering on looping gifs when sped up. I manually tested and found what was going on. FFmpeg failed to apply the speed filter to the first few frames of the video.

    


    I started with this file, which loops between the numbers "1 2 3 4" every frame.

    


    123410fps.mp4

    


    I then ran the command ffmpeg -i 123410fps.mp4 -vf setpts=0.5*PTS 123410fpsout.mp4

    


    That left me with this file : 123410fpsout.mp4

    


    On close analysis, I discovered that the output file didn't show a repeating 1 3 1 3 or 2 4 2 4 pattern, but shows 1 2 3 4 1 3 1 3 1 3... the speed effect didn't apply for the first few frames

    


    I apologize if it sounds like i'm being super nitpicky, but my usage for this is on very short gifs and videos where this effect is very apparent. How can I prevent this effect from happening and have a 100% consistent speed effect applied to the video ? I don't mind using other non-ffmpeg software but a CLI solution that works easily for most videos is ideal.

    


    In case anyone is wondering, I don't use ffmpeg to encode gifs, i use gifski from ffmpeg exported image sequences. The problem shows up even when no gifs are used, so it's not a gifski problem.
