  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • Cloaked Archive Wiki

    16 mai 2011, par Multimedia Mike — General

    Google’s Chrome browser has made me phenomenally lazy. I don’t even attempt to type proper, complete URLs into the address bar anymore. I just type something vaguely related to the address and let the search engine take over. I saw something weird when I used this method to visit Archive Team’s site :



    There’s greater detail when you elect to view more results from the site :



    As the administrator of a MediaWiki installation like the one that archiveteam.org runs on, I was a little worried that they might have a spam problem. However, clicking through to any of those out-of-place pages does not indicate anything related to pharmaceuticals. Viewing source also reveals nothing amiss.

    I quickly deduced that this is a textbook example of website cloaking. This is when a website reports different content to a search engine than it reports to normal web browsers (humans, presumably). General pseudocode :

    PLAIN TEXT
    C :
    1. if (web_request.user_agent_string == CRAWLER_USER_AGENT)
    2.  return cloaked_data ;
    3. else
    4.  return real_data ;

    You can verify this for yourself using the wget command line utility :

    <br />
    $ wget --quiet --user-agent="<strong>Mozilla/5.0</strong>" \<br />
     http://www.archiveteam.org/index.php?title=Geocities -O - | grep \&lt;title\&gt;<br />
    &lt;title&gt;GeoCities - Archiveteam&lt;/title&gt;

    $ wget —quiet —user-agent="Googlebot/2.1"
    http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\>
    <title>Cheap xanax | Online Drug Store, Big Discounts</title>

    I guess the little web prank worked because the phaux-pharma stuff got indexed. It makes we wonder if there’s a MediaWiki plugin that does this automatically.

    For extra fun, here’s a site called the CloakingDetector which purports to be able to detect whether a page employs cloaking. This is just one humble observer’s opinion, but I don’t think the site works too well :



  • FFmpeg - add an animated gif (cropped by mask) to the video

    11 mars 2021, par zeromodule

    I have 3 inputs :

    &#xA;

      &#xA;
    1. Video file : https://file.io/6jtUlnZ7TGmT

      2. &#xA;

    2. Animated GIF with transparent background https://i.imgur.com/Vo3KHZm.gif

      3. &#xA;

    3. Mask file (BW) the same resolution as the video https://i.imgur.com/YJXUUrZ.png

      4. &#xA;

    &#xA;

    I want to put the image on the video, but throw out all GIF pixels that are transparent in the mask (replace them with transparent ones).

    &#xA;

    Video
    &#xA;Mask
    &#xA;Image
    &#xA;Result

    &#xA;

    My current command, without masking (it works fine) :

    &#xA;

    ffmpeg -i input.mp4 -ignore_loop 0 -i animation.gif \&#xA;-filter_complex "[1]scale=700x700[scaled_gif];\&#xA;[0][scaled_gif]overlay=50:30:shortest=1" \&#xA;-codec:a copy output.mp4&#xA;

    &#xA;

    UPDATE #1

    &#xA;

    I managed to get closer to my goal with this command :

    &#xA;

    ffmpeg -y -i input.mp4 -loop 1 -i mask.png \ &#xA;-filter_complex "[1:v]alphaextract[mask]; \&#xA;movie=animation.gif,scale=1920x1080[scaled_gif]; \&#xA;[scaled_gif][mask]alphamerge[masked]; \&#xA;[0:v][masked]overlay=0:0" \&#xA;-c:a copy output_masked.mp4&#xA;

    &#xA;

    but it has 2 problems :

    &#xA;

      &#xA;
    1. GIF loses it's transparency. Transparent pixels become white.

      2. &#xA;

    2. GIF plays only once (i.e. no loop)

      3. &#xA;

    &#xA;

    Output : https://file.re/2021/03/11/outputmasked/

  • avcodec/h264_picture : don't assume Film Grain Params side data will be present

    17 octobre 2021, par James Almer
    avcodec/h264_picture : don't assume Film Grain Params side data will be present

    If a decoding error happens before frame side data is allocated, this assert may be
    
triggered. And since applying film grain is not enforced (we just warn it wasn't
    
applied and move on), we can just do that in such scenarios.
    

    Fixes : Assertion failure
