    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • ffmpeg image to video sequence stops after 10

    18 mai 2012, par Jim

    Probably a fast anwser, but my first time trying to do this. I have 77 jpeg pictures, I have renamed them to be 000.jpg - 076.jpg. The next step is using ffmpeg and here is my command statement :

    ffmpeg -f image2 -r .1 -i %d.jpg -r 25 test.avi

    It creates an avi with 10 images for 10seconds each, why only 10 ? I've tried other iterations of %d.jpg in the ffmpeg command with no success.

    thanks for the help all !

    -Jim

    Here is the listing of the directory with the images :

    19 mai 2012, par Pjack

    I am using ffmpeg to create video file from by using the loop_input command and create an flv file as a wrapper then export it as mp4. For some reason when the video plays the image is clear as time goes on it starts to get really pixelated. Is there something I need to do to retain the quality during the looping or anywhere else that would help ?

    This is my video out parameters, not the whole line.

    ffmpeg -loop_input -f image2 -i myimage.jpg -r 20 -g 20 -vcodec flv
