    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
    Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

  • Composition on ffmpeg does not match sizes

    24 mai 2016, par Dbugger

    I am trying to take 3 videos and an image, and make a composition of 10 seconds roughly like this :

    enter image description here

    This is the command I got so far. (I formatted it a little, so that is more readable)

    On the first 3 filters, I try to fill/crop the videos, to match 512x288
    On the next filters crop/fill the image to 640x874
    on the next 2 filtes, I add some padding to the top and middle video, of 5 pixels.

    The total height of the left column should be 288*3 + 5*2 = 874

    But when I run this command I get this error :

    Input 1 height 874 does not match input 0 height 872.

    Where did those 2 pixels go ? If instead of videos on the left, I use images, it works alright. Only with some videos, it seems to destroy those extra 2 pixels somehow.

    What is going on ? How could I fix it ?

    UPDATE
