  • 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.

  • FFMPEG and HTTPS

    14 juin 2012, par Joel

    ffmpeg lists http as a protocol when I ask : ffmpeg -protocols

    Does this also mean support for a https url ? Do I need to encode this url somehow for the command line. I get "No such file or directory", but with http urls (at least some) it does work.

    A url (created for a Amazon S3 bucket) similar to this one does not seem to work :
    https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&Expires=1323709667&Signature=pTvS9F2do2t8%3D

    I suspect the format of the url is problematic, I've also tried enclosing in quotes... Yes, this URL does not currently work as it has expired, but even while its valid, its a problem.

    In short :
    1) Should https work ?
    2) Do I need to format the url somehow ?

  • ffmpeg not working with filenames that have whitespace

    1er avril 2017, par cmw

    I’m using FFMPEG to measure the duration of videos stored in an Amazon S3 Bucket.

    I’ve read the FFMPEG docs, and they explicitly state that all whitespace and special characters need to be escaped, in order for FFMPEG to handle them properly :

    See docs 2.1 and 2.1.1 : https://ffmpeg.org/ffmpeg-utils.html

    However, when dealing with files whose filenames contain whitespace, ffmpeg fails to render a result.

    I’ve tried the following, with no success

    ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
    
ffmpeg -i "http://s3.mybucketname.com/videos/my video file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
    
ffmpeg -i "http://s3.mybucketname.com/videos/my'\' video'\' file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
    
ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d

    However, if I strip out the whitespace in the filename – all is well, and the duration of the video is returned.

    Any help is appreciated !
