    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 (...)

  • Manually feeding x264 with my own motion data ?

    6 septembre 2011, par ldoogy

    I am trying to encode a stream using x264 (by feeding individual images), but what's unusual is that I already have some motion information for my frames. I know exactly which areas have been modified in each frame, and I know where motion has occurred in the frame.

    Is there a way to feed x264 my own motion information ? I'd like to give it motion vectors for given areas in the frame, and somehow tell it that certain areas in the frame are guaranteed to not have had any motion in them.

    I think this might significantly improve the performance of the encoding (because I'm allowing the codec to completely skip the motion estimation phase), and should also somewhat increase quality in cases where the encoder's motion estimation algos might have missed the motion that actually occurred.

    Do I need to modify the encoder in order to do this, or is this supported in the existing API ?

  • Optimizing Painting video encoding in Android

    26 octobre 2013, par coder000001

    I want to create live painting video as export feature for a painting application.

    I can create a video with a series of images, with the use of a library ( FFMPEG or MediaCodec). But, this would require too much processing power to compare the images and encode the video.

    While drawing, I know exactly which pixels are changed. So, I can save lot of processing if I can pass this info to FFMPEG, instead of having the FFMPEG figure this out from the images.

    Is there away to efficiently encode the video for this purpose ?

  • Adding a filter and title cards to user uploaded videos [on hold]

    5 septembre 2013, par Django Reinhardt

    A client is interested in applying a Sepia style filter, as well as title cards, to user-uploaded videos on their website. This would obviously be automated on their webserver, and it seems ffmpeg is a good way to make this happen.

    Unfortunately, from what I've read, such processing would require a lot of webserver CPU power — far more than the average webserver usually has. How can I practically perform these calculations on a website ?
