  • 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 (...)

  • Looking for a multimedia SDK (open source or paid) which can play audio (.mp3, .aac) and video (.mp4 etc.)

    8 avril 2022, par AhmadH

    I would like to embed audio (and video) files in my cross platform application.
Searching for an SDK with below functionality :

    


      

    1. Play audio - .mp3,.aac (are must) & other common formats

      2. 


    2. Play video - .mp4 & other common formats

      3. 


    3. Audio recording would be an added advantage.

      4. 


    4. Open source or affordable price

      5. 


    


    [ Note : FFmpeg is not an option due to some License restriction]

    


    **Anything that has all FFmpeg properties would be ideal.

    


    Looking online but haven't found any suitable option.
Please help.

    


  • FFmpeg black screen using mpeg2video

    16 juin 2020, par Konata

    I have a proprietary piece of hardware for broadcasting, that accepts extremely specific video format.
The software that we use for it is extremely slow and outdated.

    



    I was looking at adapting FFmpeg to convert .avi/.mp4/etc to the specific format which in our case is

    



    


    .mpg ( 720*576 16:9, 25FPS, MPEG Video PAL v.2 (Main@High) BVOP)
 acceptable bitrate is 9000k - 15000k.

    


    



    So I have constructed this FFmpeg command :

    



    -i input.avi -codec:a mp2 -b:a 384k -c:v mpeg2video -aspect 16:9 -bf 2 -b:v 10000k -maxrate 10000k -minrate 10000k -bufsize 5000k  -profile:v main -level:v 4.0 output.mpg

    



    The audio is working fine, but instead of video I get a black screen, this is the conversion log

    



    "E:\auto_video\ffmpeg\bin\ffmpeg.exe" -i input.avi -codec:a mp2 -b:a 384k -c:v mpeg2video -aspect 16:9 -bf 2 -b:v 10000k -maxrate 10000k -minrate 10000k -bufsize 5000k -r 25  -profile:v main -level:v 4.0 output.mpg

    Additional info that might help, I get black screen in MPC-HC, Windows Media Player, and the actual hardware that I converted it for. But it plays fine in VLC

    


  • Fill output video with black screen in case of missing the input stream or switch input UDP stream to another source

    13 mai 2018, par Omar Mahmoud

    I am using FFMPEG to record a streams from UDP sources, but unfortunately once the input stream missed, the ffmpeg stop recording, then append video to file once the stream observed by the server again.

    And as these recording files is time based so, I need fill video with black screen in case of missing the input stream.

    ffmpeg -i ’udp ://224.12.12.1:4000’ -t 00:45:00 -vcodec copy -acodec copy -f mpegts /record/eEs1526947.ts

    How can I do this, either by ffmpeg or other CLI based service/process ?
