    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • 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 ?

  • 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 :)

  • Rails preview for active storage videos not working

    17 mai 2022, par Freebian

    I have a pretty standard model where you can upload videos - so far so good.
The video gets uploaded and is also displayed on the show view. Alle seems to be fine....but :

    


    I cannot get a preview fo to work.

    


    ActiveStorage::Blob.last.previewable?
--> false


    


    ActiveStorage::Blob.video?
--> true


    


    FFMPEG is installed on the system and in the gem file

    


    which ffmpeg   
--> /usr/local/bin/ffmpeg

gem 'streamio-ffmpeg'



    


    And of course if I run preview directly, I get an error

    


    ActiveStorage::Blob.last.preview(resize: "200x200>").processed
--> ActiveStorage::UnpreviewableError (ActiveStorage::UnpreviewableError)



    


    Previewers is having video included

    


    Rails.application.config.active_storage.previewers
--> [ActiveStorage::Previewer::PopplerPDFPreviewer, ActiveStorage::Previewer::MuPDFPreviewer, ActiveStorage::Previewer::VideoPreviewer]



    


    I also tried different video formats, but nothing works and I am out of ideas where to look.
Anybody had the same issue ?
