  • 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.

  • Is there a way to handle discontinuities with FFMPEG ?

    16 avril 2020, par Dave Stein

    I am running ffmpeg like this, to get a screenshot from an HLS manifest :

    



    ffmpeg -i 'https://example.com/myfile.ism/manifest' -vframes 1 test.jpg -y

    



    There are times where there are gaps in the HLS manifest. When I run that command, it fails because it can't find a frame. Is there anything I can do to make it more resilient ? ie if it fails getting the time this very second, try the second before that ?

    



    When I watch the video in something like video.js, or even HLS directly in Safari, I see a frame regardless of gaps. It just jumps sometimes - I always see a frame.

    



    How would I be able to replicate that here such that the ffmpeg command will always return a frame ?

    16 décembre 2011, par njai

    Video capture device is kworld dvd maker 2 (em2861)
    It returns the image in "black and white" with green line at the bottom of screen ; but when I tested it with webcam, it worked properly.

    Here is 30s video. http://www.youtube.com/watch?v=7q2wFGVwGGI

    How can I convert it to color ?
