  • 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 : how to extract multiple clips from a movie at once

    24 septembre 2019, par Ginso

    Now I can extract a clip from a movie using

    ffmpeg -i movie.mp4 -ss 01:05:10 -t 00:01:30

    now, I want to extract a few clips from one movie and especially those late in the movie take very long. I guess ffmpeg has to decode the whole movie up to that clip. Is there a way to extract all clips with one command, so that ffmpeg has to go through the movie only once ? The clips don’t overlap

  • Manual audio sync with ffmpeg

    2 juin 2019, par Serg

    I have 2 inputs : video and audio. Both inputs are 287 sec delay.
    And audio has 10 second sync issue.

    what I want is shift audio either forward or back with 10 sec and always keep the video length.

    V -----------------

    A xxx-----------------

    OR

    V -----------------

    A --------------xxx

    for that I’m using :

    ffmpeg -y -i video_only.mp4 -i audio_only.aac -filter_complex "[1]adelay=10s|10s,asetpts=PTS-STARTPTS[a]" -map 0 -map [a] -c:v copy -t 287 out.mp4

    and

    ffmpeg -y -i video_only.mp4 -i audio_only.aac -filter_complex "[1]atrim=start=10,asetpts=PTS-STARTPTS[a]" -map 0 -map [a] -c:v copy -t 287 out.mp4

    Could you please recommend better way to do it ? For example in some cases audio could be longer than video file, and this is why I need to specify -t 287 all the time. Can I avoid -t if I use apad in conjunction with atrim and use -shortest or it’s not possible ? Because when I’m trying to do it, mixing process doesn’t stop even in hours...

    I also saw some examples with -ss and -itsoffset. Do they faster than atrim,adelay ? And most important part I need 100% accuracy.

    Thanks in advance !
