  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • ffmpeg / video processing : make video repeat itself without duplicating content ?

    31 mars 2022, par RocketNuts

    Suppose I have a video file that is 20 MB in size and lasts 30 seconds.

    


    I want to create a new video file that basically consists of the existing video, repeated 10 times. So the new video should last 300 seconds (5 minutes) and contain the same content every 30 seconds.

    


    I could of course append this video to itself 10 times, resulting in a file of approximately 200 MB. But this seems very redundant, since obviously the same content is in there tenfold. I was hoping for a somewhat more intelligent approach, where the same 30 seconds of video is somehow 'referenced' 10 times over.

    


    Do common encoders or container formats (say h.264 in a .mp4 or .mkv container) support this ? And by any chance is there a way to pull this off with ffmpeg ?

    


  • How to put a video inside a frame and record whole thing as a video ?

    7 octobre 2024, par crysis

    I have a video. I want to create a new video such that the video plays inside a frame similar to this screenshot. Loom recording does this. Most of the screen recorders do this.

    


    enter image description here

    


    This screenshot is of the video. This is done in most of the screen recorders. Here is what I'm thinking

    


      

    • render video on a canvas with the background.
    • 


    • Play the video
    • 


    • Use mediarecorder API to record a new video.
    • 


    


    I don't have good understanding of frontend development. Is that how it is generally done or I need to use ffmpeg ? I would really appreciate any guidance here.

    Bottom left : ffmpeg -i input.mp4 -i logo.png -filter_complex "overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2" -codec:a copy output.mp4

    


    Top right :
ffmpeg -i input.mp4 -i logo.png -filter_complex "overlay=main_w-overlay_w-5:5" -codec:a copy output.mp4
