  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • FFMPEG Control Duration Of Video Watermark ? [duplicate]

    20 février 2017, par Briana Wilson

    This question already has an answer here :

    So far I have this code which allows me to batch watermark videos using FFMPEG :

    for %%a in ("C:\filepath\*.mp4") do ffmpeg -i "%%a" -q 40 -s 640x480 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2 [out]" "C:\filepath\%%~na.mp4"

    What I’m trying to figure out is how I can control the duration of the watermark so that it appears 60 seconds into the video and disappears 15 seconds later.

    Any guidance or help in figuring this out would be greatly appreciated.

    P.S. I need the code to be able to be run in batch.
