  • 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 picture in picture

    19 février 2016, par Jalyo

    I try to put a portion of video in a video at a certain time.

    Se here’s my command :

    ./ffmpeg-3.0-32bit-static/ffmpeg \
    
-y \
    
-i main.mp4 \
    
-itsoffset -10 \
    
-i overlay.mp4 \
    
-filter_complex \
    
"[1:a] atrim=5:20 [1:a1]; \
    
[1:a1] adelay=5000|5000 [1:a2]; \
    
[0:a][1:a2] amix [outa]; \
    
[1:v] scale=120:-1 [1:v1]; \
    
[0:v][1:v1] overlay=x=25:y=25:enable='between(t,5,20)'[outv]" \
    
-map "[outv]" \
    
-map "[outa]" \
    
-c:a aac \
    
-c:v libx264 \
    
-vb 1000k \
    
-r 24 \
    
-strict -2 \
    
output.mp4

    But I’ve got "Buffer queue overflow, dropping" messages which, I think, makes my overlay.mp4 a little jerky on the output.mp4 :

    [Parsed_overlay_4 @ 0xc29d9c0] [framesync @ 0xc29da84] Buffer queue overflow, dropping.
    
    Last message repeated 50 times

[Parsed_overlay_4 @ 0xc29d9c0] [framesync @ 0xc29da84] Buffer queue overflow, dropping.=3.46x
    
    Last message repeated 5 times

    Any idea why ?

    EDIT : Forgot to say I’ve got the last version of ffmpeg => 3.0.

  • Automate file splitting with FFMPEG

    19 novembre 2018, par JSawyer

    We currently use Wowza web streaming for events and would like to take the recorded streams and split them up based on events within the stream.

    My thought would be to upload a file with the times listed and then loop through those times using FFMPEG to split the file.
