    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 (...)

  • Adding multiple subtitle streams to MP4 with FFMPEG

    5 janvier 2021, par Dragonix

    After a lot of trial and error, I managed to add multiple subtitle streams to one MP4.
However, when checking the metadata of the MP4, I see some results that I want to change, hoping someone can help me or can explain why it happened.

    



    This is the input (original MP4 to which I added subtitle streams)

    



    $ ffmpeg -i movie.mp4 
ffmpeg version 2.8.11-0ubuntu0.16.04.1 Copyright (c) 2000-2017 the FFmpeg developers
   Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 2048x872 [SAR 1:1 DAR 256:109], 2352 kb/s, 24 fps, 24 tbr, 24 tbn, 48 tbc (default)
    Metadata:
      creation_time   : 1970-01-01 00:00:00

    Metadata:
      creation_time   : 1970-01-01 00:00:00
      handler_name    : SoundHandler


    



    Then, I execute the following command. I gathered this information from different sources and I'm not an FFMPEG guru :)

    



    ffmpeg -i movie.mp4 -f srt -i nl.srt -i mk.srt -i sk.srt \
-map 0:0 -map 0:1 -map 1:0 -map 2:0 -map 3:0 \

-metadata:s:s:0 language=nld -metadata:s:s:1 language=mkd -metadata:s:s:2 language=skv \
NEW.mp4


    



    In a few seconds, the NEW.mp4 is created and when playing the video I get the video and audio that I expect and 3 subtitle streams that can be switched during playback. The subtitles itself are also what I expect to be.

    



    Output of NEW.mp4

    



    $ ffmpeg -i NEW.mp4

    I'm not sure if the type of subtitle is the one I should use -> 'mov_text'. If I use the same command but instead of using 'mov_text', I want to use 'srt' or 'subrip', I get some errors.

    



    [mp4 @ 0x7ba2c0] Codec for stream 0 does not use global headers but container format requires global headers
[mp4 @ 0x7ba2c0] Codec for stream 1 does not use global headers but container format requires global headers
[mp4 @ 0x7ba2c0] Could not find tag for codec subrip in stream #2, codec not currently supported in container


    



    The only question that remains for me is how can I make it work with 'srt' or 'subrip' ? In the meantime I will look for solutions and when found, I will put it here.

    


  • ClipBucket video upload and conversion issue

    23 mars 2018, par Aleksandr Levcenko

    I am trying to migrate ClipBucket 2.8.1, RC2, REV 4328 into a new Azure server.
    I managed to install and enable all required modules such as : FFMPEG, PHP CLI, Media Info, MP4Box, ImageMagick and FFProbe.
    Post, Upload, Execution time and Memory limit configuration values have been increased as well on the server side.

    ClipBucket seems to be up and running smoothly, but I have an issue with uploading the videos.
    After uploading a video it shows error message "This video might not work properly".
    When I checked Video Manager it stucks at Processing and does not go any further.

    I tried to delete conversion .loc file but still no luck.

    Can anyone help me with this please ?

  • ffmpeg HLS transcoding and chunks upload to remote server

    These are the supported methods on my web server :

    



    $ nmap -Pn -p 80 --script http-methods 192.168.178.100

    My web server is running apache2 on Ubuntu 16.04 :

    



    $ apache2 -v

Server version: Apache/2.4.18 (Ubuntu)
Server built:   2017-06-26T11:58:04


    



    So according to the access.log file no matter what method I define in the ffmpeg command line it is always trying to upload the chunks using HTTP POST, but the latter is already supported and the directory I am directing the chunks has even 777 rights. Am I missing something here ?
