  • 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.

  • Strange error [adding watermark to flv video with ffmpeg on linux centos 6]

    20 juillet 2012, par igor

    I have tried to do the job with following code :

    ffmpeg -i /home/igordr/video.flv -vf "movie=/home/igordr/wm.jpg [watermark]; [in][watermark] overlay=main_w/2-overlay_w/2:main_h/2-overlay_h/2 [out]" /home/igordr/outputvideo.flv

    Also tried :

    ffmpeg -i /home/igordr/video.flv -b:a 300k -ar 22050 -t 10 -f flv -s 352x288 -vf "movie = /home/igordr/wm.png [watermark]; [in][watermark] overlay =0:0 [out]" /home/igordr/out.flv

    I get errors :

    Unrecognized option 'vf'
    

    
Unrecognized option 'b:a'

    Also, I am interested, how I can add just one big image, before video starts, without watermark, and does it possible ?

    How can i check ffmpeg version, and install new one if it's old ?

  • FFmpeg libx264 Llicense

    2 juillet 2014, par user416472

    We have Java Spring application. The application interacts with FFmpeg through Java Runtime.exec() call in order to encode video into mp4 format. Are we ok with the commercial aspect of our application, having in mind that libx264 is released under GPL license, ffmpeg under LGPL license and we are using ffmpeg as external command line utility already installed and hosted on the client’s computer ?
