  • Librairies et logiciels spécifiques aux médias

    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

    Par défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.

  • ffmpeg - Record Server Desktop Without Connection

    21 janvier, par chrisp

    I set up an application which uses ffmpeg to record a desktop on an Amazon AWS EC2 instance having Windows Server 2012 R2 installed. It records the desktop and puts the result into a file.

    



    This works as long as a Remote Desktop or TeamViewer connection is active for that particular Amazon AWS EC2 instance. As soon as I close the Remote Desktop and TeamViewer connection the recording stops and continues as soon as I reconnect.

    



    I assume that it's because the GPU doesn't deliver frames without a display in use.

    



    How can I make sure that frames are constantly being rendered so that I can record them ?

    


  • 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.
