  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

Any another way of compress video If yes then please guys help to solve it !!! Thanks in advance

  • 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 ?

  • FFmpeg for marking time video based on a reference date

    29 décembre 2018, par Denio Mariz

    I am trying to mark a timestamp in a video using drawtext filter.
    FFmpeg easily marks timestamps based on localtime, gmtime or even PTS. However, I want to assign a reference time (start time) for the timestamp in order to represent the time the video was recorded (not encoded).

    Reading the documentation, I found that option basetime can be used for this purpose. However it seems that is not working or I am missing something.

    The command line I am using is :

    ffmpeg -y -i input.mp4 -filter_complex drawtext="fontfile=/tmp/UbuntuMono-B.ttf: fontsize=36: fontcolor=yellow: box=1: boxcolor=black@0.4: text='Wall Clock Time\: %{gmtime\:%Y-%m-%d %T}': basetime=1456007118" output.mp4

    By using basetime=1456007118, it was expected the start time was set to ’02/20/2016 20:25:18’ since 1456007118 is the UTC time for that time and date :

    date -d '02/20/2016 20:25:18' +"%s" # format MM/DD/AAAA hh:mm:ss
    
1456007118

    However, no error is issued by FFmpeg and the video is marked with current GMT, ignoring basetime option.

    Any hint ?
    Thanks.

    Complete information about FFmpeg version and output is :

    ffmpeg -y -i /home/denio/Videos/Interstellar_2014_Trailer_4_5.1-1080p-HDTN.mp4 -filter_complex drawtext="fontfile=/tmp/UbuntuMono-B.ttf: fontsize=36: fontcolor=yellow: box=1: boxcolor=black@0.4: text='Wall Clock Time\: %{gmtime\:%Y-%m-%d %T}': basetime=1470226363" /tmp/x.mp4
