  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg complex filter pip loop not working

    4 août 2021, par Dzseti

    I am using an ffmpeg complex filter to :

    


      

    1. turn a number of images into a slideshow

      2. 


    2. scale the slideshow to 1/6th of its original size

      3. 


    3. loop the slideshow infinitely

      4. 


    4. set the looping slideshow as a picture-in-picture over another looping video

      5. 


    


    then add audio from another file which determines the maximum length of the final video.

    


    Everything is working except step 3.

    


    Here is my code (broken down into individual lines) :

  • RNFFMpeg.executeAsync : Unable to create gif of a video with space(s) in it's source path

    7 juillet 2021, par STBox

    Unable to make gif of a video which has space(s) in it's source directory. All the other video which don't have space(s), their gif is making fine. I had a video whose folder name had space and it was not making gif for it. I copied the same video to a folder without space in it's name, and it made gif for it successfully. Even if I replace the the space with source path with anything like %20 etc, then it says

    


    


    No such file or directory

    


    


    Code snippet

    


    

    

    RNFFmpeg.executeAsync(
          `-i ${source} -ss ${start} -t ${gifDuration}  -vf "fps=5,scale=160:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 ${destination}`, (completedExecution) => {
            if (completedExecution.returnCode === 0) {
              resolve({ path: destination });
            } else {
              resolve({ error: "invalid Gif" });  // always this part executes for videos with space in their source path
            }
          }
        );

    


    


    



    Expected behavior

    


    Regardless a video has or has not a space in it's path, it should make gif correctly and

    


    


    completedExecution.returnCode

    


    


    should be 0

    


    Current behavior
Currently, for all the videos having space in their source path, completedExecution.returnCode is always 1
