  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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 !

  • rtmp audio out of sync, http works fine

    21 janvier 2014, par marca

    We have encoded and distributed videos for some years now, using FFMPEG to produce h.264/mp4 files that have been working great for us. We have been using HTML mode and fall-backed to flash for browsers that does not support it natively using flowplayer.

    We use cloudfront to serve our files from a s3 bucket and have been using http progressive streaming.

    Recently we started distribute the files in flashmode over rtmp instead, using a cloudfront streaming distribution pointing to the same amazon s3 bucket.

    All good for some weeks, until yesterday when we notice a couple of files with audio sync issues in rtmp mode.
    The same file have no sync problems in flash with direct url to file.

    What can be the case ?

    Not working when streamed via RTMP, but file work with http streaming/progressive.
    You see the sync issue 15 sec's into the video.
    rtmp ://s2xe2avk54qztf.cloudfront.net:1935/cfx/st/mp4:95fvOY255bdPspO3z6tEvGi3Em7/default.mp4
    http://media.shootitlive.com/95fvOY255bdPspO3z6tEvGi3Em7/default.mp4

    Another file that have no sync issue at all.
    rtmp ://s2xe2avk54qztf.cloudfront.net:1935/cfx/st/mp4:P4EuH2TZxfV6BvpupP6dxrrs7gD/default.mp4
    http://media.shootitlive.com/P4EuH2TZxfV6BvpupP6dxrrs7gD/default.mp4

    Both files have the same format for video and audio and have been encoded the exact same way with ffmpeg. It's not player related as we see the audio sync issue on several players and when playing stream in VLC.
