  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • avdevice/dshow : list_devices : show media type(s) per device

    avdevice/dshow : list_devices : show media type(s) per device

    the list_devices option of dshow didn't indicate whether a specific
    
device provides audio or video output. This patch iterates through all
    
media formats of all pins exposed by the device to see what types it
    
provides for capture, and prints this to the console for each device.
    
Importantly, this now allows to find devices that provide both audio and
    
video, and devices that provide neither.

  • How to generating waveform from video & show it with video

    25 novembre 2016, par Salil

    We are using Rails as a backend & AngularJS on Front End side in my App where we need to show Video & audio waveform of that video.

    We are using ’wavesurfer.js’ to show the waveform on Front End side & ’node-pcm’ to generate pcm from video file on BackEnd side.

    This is working as expected but in some of the videos while creating waveform from pcm data instead of showing small sine waves we get flat line.
    Also it takes too much time to show the waveform for every page reload.

    To overcome this issue we are planning to create waveform image using ffmpeg

    ffmpeg -i 'https://s3.amazonaws.com/aadasdsadsadasdas/xyz.mp4' -filter_complex showwavespic -frames:v 1 output.png

    This is working fine but it also takes too much time (Ofcourse only once ) to generate the image for remote video (i.e. We are saving videos on S3)

    Problem with this i don’t get any library to integrate the waveform image with the Video.

    Can someone suggest any better approach related to this.
