  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    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.

  • Can FFmpeg perform audio phase subtraction ? [closed]

    22 avril 2023, par Calarpo

    I can do audio phase subtraction in Adobe Audition like so : https://www.youtube.com/watch?v=vNvJKBg3yds

    


    How can I do this with FFmpeg ? Is it possible ?

    


    I've googled for audio phase subtraction, and looked at https://ffmpeg.org/ffmpeg-filters.html, nothing seems to work for me.

    


    I want to do phase subtraction in batches and support for stereo audio.

    


  • Increasing speed of a video in C# ?

    13 décembre 2017, par alan samuel

    I am trying to increase the speed of a video using NReco.VideoConverter.FFMpegConverter

    Here is what I have tried.

      var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
    
  string inputfile = @"C:\Users\Alan\Desktop\Video.flv";
    
  string outputfile = @"C:\Users\Alan\Desktop\converted.mp4";
    

    

    
  ConvertSettings convertSettings = new ConvertSettings
    
        {
    
            MaxDuration = 10,
    
            VideoFrameRate = 12
    
            //VideoFrameCount = 10
    

    
        };
    

    
ffMpeg.ConvertMedia(inputfile,Format.flv, outputfile,Format.mp4,convertSettings);

    What I want is like a video with an increased playback like in this example - https://www.youtube.com/watch?v=6tQ1ewhGiwk

    This is what I am basically trying to do.

  • Compression of a video with constant background

    28 juin 2017, par Spirou003

    (sorry if my english is bad, I can read it but I don’t write it quite well...)

    I want to compress some videos, which have two particularities :

    • there is a background that covers 90% of the area, during the whole video
    • most of the others elements can be separately described by a picture in move

    My videos are like this one, and don’t have audio. As you can see, almost everything can be described only by using a fixed background, few small images in move, plus a noise. Moreover, this noise will be almost nul and then an entropic coding would be very efficient. I think it will produce tiny files (< 5 Mo) even if the duration is in hours, a result that is very appreciable since I have actually recorded 30h of game (actual size is 3 Go).

    Is there any way to get new video files, that benefit of these informations ? If yes, what are the implication of a such encoding for watching these videos with Windows Media Player, or for usage with ffmpeg ?

    I searched with Google after anything that can help me, but I don’t know which keyword I can use for this, then I didn’t found anything usefull :-(

    Thanks in advance :-)

    PS : another example, the video is accelerated but shows the interesting moves
