  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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" (...)

  • Create muted video and black screen video with FFmpeg on OS X

    22 septembre 2017, par user2685832

    I’m trying to use FFmpeg on OS X to generate the following from a local mp4-file :

    • A copy of the original video with no audio
    • A copy of the original video with audio but without visuals (a black screen instead). This file also needs to be in mp4 format.

    After reading through the documentation I am struggling to get the terminal commands right. To remove the audio I have tried this command without any success :

        ffmpeg -i file.mp4 -map 0:0 -map 0:2 -acodec copy -vcodec copy

    Could anyone guide me towards how to accomplish this ?

    Thanks !

  • ffmpeg : given a video of any length, create timelapse video of 6-8 seconds long

    14 mai 2018, par CDub

    I have an application which consumes video of any length (could be a few seconds, could be several minutes) and I want to use ffmpeg to return a "timelapse" version of the input video which will always be between 6 and 8 seconds long.

    I’ve been fiddling with the following :

    ffmpeg -y -i in.mp4 -r 10 -vf setpts='0.01*PTS' -an out.mp4

    Which seems to be a good start, but still generates very dynamic results given what in.mp4 is.

    I also don’t fully understand the verbiage in the ffmpeg documentation, so I’m not even sure what arguments to use for setpts, or if setpts is the correct filter I want to use.

  • Is there a way to display video, then an image, then more video using OpenCV ?

    24 septembre 2015, par kdibene1

    I have a bunch of frames (jpg images) and want to stitch some of them together and make a video, then display one image (essentially repeating the same frame for a number of seconds) and then stitch more frames together and continue playing the video. I want it to be continuous with no interruptions, is this possible ? I know about avconv and ffmpeg, but they only stitch together frames and make a video, they do not simply display a frame over and over again like with ImageMagick. Essentially what I want to do is take a bunch of image frames, stitch them together to an arbitrary point, then display an image, then stitch together the remaining frames to a video.

    Can anyone help ?
