  • 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.

  • Converting video to .mp4 format after upload from local system does not show the video only hear sound

    18 juillet 2012, par user850234

    I am using fileuploader.js to upload a video file. Now i want to convert the video format to .mp4. I have used ffmpeg and php to convert the video to .mp4 after upload. The sample segment i used is

    $converted = "uploads/".$uniqid.".mp4"; //$uniqid is the id for the video after upload
    
$cmd = "$ffmpeg -i $sourceUrl -f mp4 $converted"; //$sourceUrl is the path of the video

    I have tried to convert .flv video file to .mp4 format and it does but the problem is i cannot see the video only hear the sound after converting. Is the conversion line used in $cmd incorrect. Please help.

  • Create video with size based on image and place a video somewhere with an offset

    10 mars 2024, par NoKey

    I am trying out FFMPEG and I am unsure how hard it is to do what I want. I have some device frames and I want to play a video inside the frame. For example, this is a device frame :

    


    enter image description here

    


    Now I want to play a video within the screen of the iPhone. I already got the exact X and Y offset where the video must be placed to show it correctly. I have the following challenges to make it work, and I want to make sure FFMPEG can do it before I spend to much time reinventing the wheel :

    


      


    • The output of the video must be as big as the PNG. This is already a
confusing part for me. I have the width and height already available,
but the things I saw is that FFMPEG will take over the input of the
video as final size. The final output of the video should of course
be the length of the input video.

    • The background must be transparant (so no black background, I want to
play the video on top of a website so it's nice if it's transparant and the corners are not black).

      


      • 


    • The ability to place a video somewhere with a specified X and Y
offset inside the device frame.

      


      • 


    • Not sure if it's possible in the same command, but maybe the video
needs to be resized to make it fit. I got the exact dimensions for
the video.

    The things I struggle most is point 1 where the output video must have a transparant background and where the device frame is placed in. Does anybody got tips ?

    8 juillet 2023, par Doğan

    I have a video in .webm format with a transparent background, and I would like to overlay this .webm video on the right down side of the main video. The main video is in .mp4 format.

    


    Is there any way to do it with python ?
