  • 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" (...)

  • ffmpeg generate video from images timestamped

    11 février 2020, par user3262532

    I have a set of timestamped image as input and I want to generate a output video from it.

    My command is :

    ffmpeg   -f image2 -ts_from_file 1 -i './%*.jpeg'    './video.avi'

    As output I get many errors :

    ....
    
[mjpeg @ 0x5591f1d5f100] bits 121 is invalid
    
Error while decoding stream #0:0: Invalid data found when processing input

    The output video is not properly generates, the video file has the good framerate but visually the video is run too quick.

    I try many commands to get proper output but I can get it.

  • Precise syncronized stream Recording

    15 octobre 2020, par LuckyLuke1984

    I have multiple streams from cameras and I would like to capture an event from different point of views. My program opens at the moment X at once for each of these streams a different process that is calling an instance of ffmpeg to record the stream.
The problem is that the moment Y where the event happens is not exactly after Z seconds in each recorded file. There is a mismatch between each stream, resulting from different starting times of the videos.

    


    How can I trigger the start of the recording more precisely ?

    


  • combine Scheduled audio ffmpeg

    5 septembre 2018, par Erfan Esmaeilzadeh

    I am developing a music making application for Android. I need to create a system that can extract MP3s from the user’s music project.

    I can save the name of every file per second of music in a string, as in the following example :

    a.mp3-b.mp3-c.mp3|| d.mp3-e.mp3-f.mp3|| g.mp3-h.mp3-i.mp3
    

    
=> final.mp3

    Between "||" is equivalent to one second and the audio within this parameter must be combined. After that, the combinations are put together.

    The most important thing is the timing of each sound. Some sounds must be combined at one time and some sounds at other times.
