  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • How do I concat two video mp4 files, each of which has an audio of different sample rates with ffmpeg

    14 août 2020, par Geo

    I have two videos : video1.mp4 and video2.mp4 in the configured txt file, both videos have mp3 audios :
video1.mp4 has : Audio : mp3, 32000 Hz, mono, fltp, 48 kb/s
video2.mp4 has : Audio : mp3, 24000 Hz, mono, fltp, 32 kb/s
I need to keep the different sample rates since I need to change the pitch to make it sound different from the real voice of the person, now I tried to merge the two videos by concatenating them :

    


    ffmpeg -safe 0 -f concat -segment_time_metadata 1 -i videoconf.txt -vf select=concatdec_select -af aselect=concatdec_select,aresample=async=1 -y videoout.mp4

    


    but I got a lot of errors like these :

    


    [aac @ 0x730e491e00] channel element 2.12 is not allocated

    


    index.js:81 Error while decoding stream #0:1 : Invalid data found when processing input

    


    index.js:81 [aac @ 0x730e491e00] TYPE_FIL : Input buffer exhausted before END element found

    


    index.js:81 Error while decoding stream #0:1 : Invalid data found when processing input

    


    ......

    


    So how can I concatenate multiple videos with different audio sample rates inside each video ?
By the way, when the sample rates are the same for all the audios inside each video, the concat works like a charm.

    


    Thanks

    


  • FFMPEG Sample example does not work

    27 juin 2017, par Davood Falahati

    I have been struggling in getting ffmpeg sample to work. I had a tough time upgrading sample code according to the latest commits. I have uploaded my code here

    When I run this code, however, I get the following error :

    [libx264 @ 0xee2400] broken ffmpeg default settings detected
    
[libx264 @ 0xee2400] use an encoding preset (e.g. -vpre medium)
    
[libx264 @ 0xee2400] preset usage: -vpre <speed> -vpre <profile>
    
[libx264 @ 0xee2400] speed presets are listed in x264 --help
    
[libx264 @ 0xee2400] profile is optional; x264 defaults to high
    
</profile></speed>

    And the av_codec_open2 function fails to open the video and find the proper codec. Here is the specifications of my video, if it helps :

    Output #0, mov, to '/home/dfalahati/Videos/melissa.MOV':
    
Stream #0:0: Video: h264, yuv420p, 352x288, q=2-31, 400 kb/s, 25 tbc
    
Stream #0:1: Audio: aac, 44100 Hz, 2 channels, 64 kb/s

    I used @gabi-davar answer here to make the code run, but there are some unfamiliar errors still with it. Is there any advice how to solve it ?
