  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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.

  • FFMPEG : Overlay Capture Time (w/Counter)

    27 juin 2022, par AdamK

    I am using the Shutter Encoder application on Windows to batch convert .MOV files, which provides the option of injecting custom FFMPEG commands for each file. The app natively offers overlay (drawtext) of timecode starting at 00:00:00:00. I also see that it knows and preserves the metadata time for each file as this is included in the commands "-metadata creation_time="2022-06-27T16:00:30.730888500Z"

    


    I would like to have the timecode start at the creation time, and was wondering how I might be able to offset the timecode as such. Or...is there another way of overlaying (drawtext-ing) a time counter, starting at creation time ? I would also like to overlay the creation date as well. Thanks in advance for your advice.

    


  • FFMPEG : Create timestamp based on actual creation time

    2 juillet 2022, par Peder Wessel

    Desired outcome

    


    Add overlay with timestamp for each frame of a video based on the original creation time for the video. E.g. starting at 2022-03-26T15:51:49.000000Z and a second later in the video present 2022-03-26T15:51.50.000000Z

    


    Approach

    


    Creation_time stored in the file already, e.g. when running ffmpeg -i input.mov" it presents creation_time   : 2022-03-26T15:51:49.000000Z.

    


    Adding overlay with timestamp to video :
ffmpeg -i input.mov -filter_complex "drawtext=text='%{pts\:gmtime\:1507046400\:%d-%m-%Y %T}': x=100 : y=100: box=1" -c:a copy output.mp4

    


    Challenge/ help needed

    


    Need to replace the gmtime\:1507046400 with the actual creation_time. How does one do it ?

  • Silenced parts are removed when converting from .mka into .wav using ffmpeg

    29 mars 2022, par Test Account

    I am trying to convert .mka audio into .wva. But the duration is changed from 26s to 14s and also the silenced parts in the .mka audio are removed.

    


    The media informations of input and output are given below.

    


    Input Audio (test.mka) :

    


        Input #0, matroska,webm, from 'test.mka':
    Metadata:
    encoder         : GStreamer matroskamux version 1.16.2
    creation_time   : 2022-03-25T18:35:04.000000Z
  Duration: 00:00:27.07, start: 177.258000, bitrate: 23 kb/s
  Stream #0:0(eng): Audio: opus, 48000 Hz, stereo, fltp (default)
    Metadata:
      title           : Audio


    


    Output Audio(output.wav) :

    


       Input #0, wav, from 'output.wav':
      Metadata:
        encoder         : Lavf59.20.101
      Duration: 00:00:14.30, bitrate: 1536 kb/s
      Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 48000 Hz, 2 
      channels, s16, 1536 kb/s


    


    Silenced parts should not be removed and durations should be same.
