  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Programmatically get non-overlapping images from MP4

    16 novembre 2019, par Carlos F

    My ultimate goal is to get meaningful snapshots from MP4 videos that are either 30 min or 1 hour long. "Meaningful" is a bit ambitious, so I have simplified my requirements.

    The image should be crisp - non-overlapping, and ideally not blurry. Initially, I thought getting a keyframe would work, but I had no idea that keyframes could have overlapping images embedded in them like this :enter image description here

    Of course, some keyframe images look like this and those are much better :

    enter image description here

    I was wondering if someone might have source code to :

    Take a sequence of say 10-15 continuous keyframes (jpg or png) and identify the best keyframe from all of them.

    This must happen entirely programmatically. I found this paper : http://research.microsoft.com/pubs/68802/blur_determination_compressed.pdf

    and felt that I could "rank" a few images based on the above paper, but then I was dissuaded by this link : Extracting DCT coefficients from encoded images and video given that my source video is an MP4. Of course, this confuses me because the input into the system is just a sequence of jpg images.

    Another link that is interesting is :

    Detection of Blur in Images/Video sequences

    However, I am not sure if this will work for "overlapping" images.

  • Revision 5d2f6baac3 : thumb : Adjust the conversion of the position independent switch This is require

    15 mai 2013, par Martin Storsjo

    Changed Paths :
     Modify /build/make/thumb.pm



    thumb : Adjust the conversion of the position independent switch

    This is required since the microsoft assembler claims that
    add.w r12, pc, #10
    generated unpredictable behaviour.
