  • 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" (...)

  • Add multiple timecodes to single audio file (.mkv ?) resulting from concatenating several (timecode-based) audio files

    6 juin 2020, par user3497017

    I first converted two .WAV files into .MKV files inserting timecode for each of this file. Then I concatenated these two .MKV files as inputs (each .MKV including one timecode inside). However timecodes were not maintained in the final output.MKV. I tried :

    



     1. ffmpeg -f concat -i mylist.txt -c copy output.mkv  
 2. mkvmerge -o output.mkv 1.mkv + 2.mkv


    



    with mylist.txt containing :

    



    file '1.mkv'
file '2.mkv'


    



    But the final file output.mkv resulting from such a concatenation has lost timecodes in case 1. In case 2, there is only one time code that has been preserved (from input 2.mkv) at the end. According to mediaInfo command line. I was expecting 2 times codes issued from 1.mkv and from 2.mkv. But is it the right approach ? (Is it even do-able ?)

    



    To summarize, my goal is to insert multiple time codes along with / inside a single audio file (.WAV, or .MKV, or whatever). Here is a sreenshot that technically depicts my purpose enter image description here

    


  • FFMPEG zoompan filter cut short my video and slowed it down [on hold]

    9 décembre 2018, par Ewan Sou

    I am using FFMPEG (version 4.0.2) to zoompan my video. My code is as below

    ffmpeg -y -i input.mp4 -loop 1 -i overlay.png -ss 0 -t 10 -filter_complex "[0:v]scale=iw+iw:ih+ih, zoompan=z='if(lte(pzoom,1.0),1.6,max(1.001,pzoom-0.004))':d=1:x='iw/2-(iw/zoom/2)':y='0':s=720x720, setsar=1 [v0];[1:v]crop=720:720,fade=t=in:st=0:d=1,fade=t=out:st=3:d=1[v1];[v0][v1] overlay [v]" -map "[v]" -f mp4 -preset ultrafast -y output.mp4

    Essentially, what this code should do is slowly pan out from the center of my video, with a logo (overlay.png) fading in and out.

    This input.mp4 is 10 seconds. With the above code, the final video duration is 10 seconds still. But its not the full footage, it is cut short and compensated with slow motion to make it 10 seconds still...

    I need the final video to not be cut off at all. It should be the full footage and no slow motion effect.

    Anyone has any ideas what I am doing wrong ?

    Thanks in advance !

  • Where can I find a C/C++ FFmpeg extensive tutorial ?

    5 janvier 2013, par fabio

    I want to use ffmpeg (in its c library form) to split a video in more parts, recompose them and encode the final result. Something basic. But it's very difficult to find documentation or hints about this. Where should I look/ask for advice ?
