    This page lists some websites based on MediaSPIP.

  • 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" (...)

    avformat/mov_chan : never override number of channels based on chan atom

    The channel designation metadata should not override the number of channels.
    
Let's warn the user if it is inconsistent, and keep the channel layout
    
unspecified.
    

    Before the conversion to the channel layout API the code only set the mask, but
    
never overridden the channel count, so this restores the old behaviour.

  • Remove frames based off an image with FFmpeg

    15 novembre 2020, par VEXED

    The Goal : Take a frame or a reference image and use that to decide what frames to keep/remove from an old screen recording (no audio).

    &#xA;

    To be slightly more specific, I want to match a specific program that is being used in the screen recording. The program is always full screen and could potentially be identified just by a crop of the top left corner.

    &#xA;

    The Question : What would be the best way to take an image, in particular a cropped corner of say 100px width and height, and look for the same matching corner in a video ? I would want to output those matches to a new file, that or remove the non-matching frames and create a new file with all the frames that match.

    &#xA;

    What I Know : I know that duplicate frame removal is very possible, and I already use that for screen recordings.

    &#xA;

    -filter:v mpdecimate, setpts=N/FRAME_RATE/TB \&#xA;

    &#xA;

    The above is being used in my screen recording script to remove duplicate frames.

    &#xA;

    I'm also aware that you can crop using FFmpeg, but I'm not looking to have actual cropped output. I'm only looking to use a crop to find the portion that matches my reference image or reference frame.

    &#xA;

    ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4&#xA;

    &#xA;

    The above is a basic crop.

    &#xA;

    The only reference to finding frames by images is this one. It didn't do what I wanted and just produced dark and distorted output. Though I might be understanding what the aim of that post was incorrectly.

    &#xA;

    Notes : Thanks in advance for any help, this frame/image matching doesn't have to be done while recording, but can be done in post.

    &#xA;
