  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Is anyone willing to join a GTK+3 project started in 2009 and still active ?

    15 mars 2020, par GiuTor

    first of all if my question is not relevant to stackoverflow website please delete it, I apologize in advance.

    I started Imagination, a DVD slideshow maker developed with GTK+2 in 2009. Along the years users have contributed with few patches. The software was ported to GTK+3 last year. Imagination works by using Cairo to paint the transition on a GTK drawing area and ffmpeg run in the background to encode the video. I’m currently getting rid of ffmpeg and using libav to encode the video.

    Does anybody want to help with libav coding ? The software is available through SVN :

    svn co https://svn.code.sf.net/p/imagination/code/trunk imagination

    The web site is hosted at sourceforge : http://imagination.sourceforge.net/

    Thanks :)

  • Preprocessing of Columbia active speaker dataset

    21 octobre 2019, par aspit794

    I would like to use the Columbia dataset (which is 1 video https://youtu.be/6GzxbrO0DHM) and its ground truth annotation (http://www.jaychakravarty.com/wp-content/uploads/2016/02/columbiaDatasetGroundTruth.zip).

    annotation contain the frame_id (int), x and y position of the bounding box (int, int), the width=height of the bounding box (int), and the ground truth for active speaker (0 or 1)

    More information : https://www.jaychakravarty.com/active-speaker-detection/

    I managed to download the video, extracted the frames with

    ffmpeg -loglevel 0 -i columbia.mkv columbia/frame_%06d.jpg -nostdin -vf -an -hide_banner

    and draw the ground truth bounding boxes to the video frames (where available).

    However, the bounding boxes are not in the correct places, and I am a bit helpless.

    I tried to convert the video to other frame rate (e.g. 25 fps), but the annotation is not fit.

    I read every paper available, which is related to this dataset, but neither of them mention any information about preprocessing, and the codebase is not publicly available.

    How should I preprocess the video to interpret the annotation ?

  • avcodec/v210enc : Pass through Active Format Description (AFD) data

    7 septembre 2018, par Devin Heitmueller
    avcodec/v210enc : Pass through Active Format Description (AFD) data

    When encoding to V210, make sure the AFD side data makes it through
    
in the resulting AVPacket.  This is needed so the decklink output
    
module can put out AFD when in 10-bit mode.
