  • 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.

  • Create 256 color palette video

    2 mars 2020, par rlcabral

    I already have this working by converting the source video to GIF with :

    ffmpeg -y -t 5 source.mp4 -vf fps=10,scale=480:-1,smartblur=ls=-0.5,crop=iw:ih-2:0:0 -hide_banner -loglevel panic output.gif

    And then converting the GIF to MP4, like so :

    ffmpeg -y animated.gif -hide_banner -pix_fmt yuvj420p -loglevel panic -an -loglevel panic final.mp4

    What I want is to convert source.mp4 directly to final.mp4, and have the same 256 color palette as a normal GIF.

    I tried merging both commands together, and although it generates a MP4, the result is a 16 bit video, surprisingly smaller than a 8 bit video.

    Do I need to generate a palette first with palettegen and then re-encode the video with this palette ?

  • Generate color palette from an image for FFmpeg

    18 mars 2018, par Peter

    I want to generate color palette from an image but FFmpeg allows to generate palettes only from videos. The only Bash tool I know that can generate color palettes from images is ImageMagick, but it generates palettes in a *.txt and I need a *.png palette.

    Is there a bash tool to generate palettes with fine control ? Or maybe there is a way to do it in FFmpeg ?

    P.S. I need that palette to create GIF in FFmpeg.

  • ffmpeg color space metadata not working for some sources

    28 août 2023, par pawel

    I have a bit of a pickle. I'm trying to change incorrect tags on mp4 videos using ffmpeg.

    


    I'm using this command (in a bat file) :

    


    ffmpeg.exe -i %1 -colorspace "rgb" -color_primaries "bt709" -c copy -y %1.sRGB.mp4

    


    I'm on windows and I'm using ffmpeg 6.0

    


    The above command sets the tags for some videos correctly for for others does nothing. The file sizes change but ffprobe still shows me the old tags. It doesn't matter what color spaces I request or if I use numbers or strings.

    


    The only difference I can see in the source videos (ffprobe) is the SAR and DAR section.

    


    Stream #0:0[0x1](und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709/bt709/iec61966-2-1, progressive), 3840x2160, 91942 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 29.97 tbr, 30k tbn (default)

    


    Stream #0:0[0x1](und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709/bt709/iec61966-2-1, progressive), 3840x2160 [SAR 1:1 DAR 16:9], 119433 kb/s, 29.97 fps, 29.97 tbr, 30k tbn (default)

    


    the values are still the same but the grouping is different. the second one is the one that is not working through ffmpeg.

    


    do I need to provide more information on the commandline ? direct it to a stream I want to alter ? I'm a bit out of my depth here and google is not helping much on this.

    


    EDIT : updated to latest ffmpeg and I get warnings telling me that my commands were ignored :

    


    Codec AVOption colorspace (color space) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

    


    however I get the same warnings on the mp4s that worked fine before and it is no longer working in the latest ffmpeg.

    


    my goal is to get from :

    


    Stream #0:0[0x1](und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, gbr/bt709/bt709, progressive)

    


    to :

    


    Stream #0:0[0x1](und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(progressive)

    


    basically I want to remove bt709 tag from it
