  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • 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) (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • avconv much longer than ffmpeg

    18 mars 2014, par fsulser

    I was using ffmpeg to generate some images from a video. Now I read that I shouldn't use ffmpeg longer and use avconv from libav instead.
    So I tried to do the same thing with avconv.

    The ffmpeg is looking like this :

    ffmpeg -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp

    Same with avconv :

    avconv -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp

    ffmpeg needs less than one second to finish. Avconv about 90 seconds for the same task.
    Is this usual or do I need to change some things to work with avconv ?

  • Working with mkfifo and transport streams, is this possible ?

    7 décembre 2017, par vedant gala

    I want to execute a bash script that would do the following :

    Application ’ffmpeg’ generates a LIVE transport stream (.ts) file. I need to work on this live streaam (perform de-multiplexing, etc).

    Now I know this has to be done via FIFOs ; but here is my task.

    I need to redirect the output of ffmpeg to write to a fifo, and then another application will work on that fifo contents. This happens continuously in real time until I press, say Ctrl+C.

    Is this possible ?
    Will I have to do this is two terminals ?

    I’m basically writing a bash script for the above operations (and more) so do I have to invoke two terminals, or maybe fork ?

    Kindly advise.

    Thanks in advance !

  • Overlay frame PNG animation over video with FFmpeg

    16 juillet 2021, par alex okochutin

    Previously, I had no experience with FFmpeg and I really need help. And this is my first question on Stack Overflow. There is a task described below, I use ffmpeg-for-android.

    



    We have an input (20 seconds long, 30 fps) mp4 video and for example 30 PNG images of the same resolution as video. We need to create a transparent looped 30 fps animation from the sequence of images. And after that, overlay the input mp4 video with the layer of the animation created in the first step. In this way if we have a 20 sec / 30 fps video and 30 images (1 second of animation), animation should be repeated 20 times during the video. Perhaps this problem can be solved more easily with the help of FFmpeg ?

    



    Can anyone help me in this matter ?
