  • 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 (...)

  • Decoding of 4k video causing overflow of buffer in a multi process application

    15 octobre 2016, par mkreddy

    I am quite new in working with FFMPEG. Please excuse me if I made any mistake while explaining my problem.

    I am working on an application where PCAP captures 1316 bytes of data split that into 188 bytes and writes it into it to corresponding shared memory. The other process reads the data and decode using ffmpeg and process it.

    This whole process is working fine with H264 and HEVC video.
    The problem comes with 4k video. While decodig the 4k video I am encountering buffer overflow.
    I have observed that on a machine with high CPU frequence the overflow rate was less. Hence If I can reduce the time taken to decode and process the video data at ffmpeg might solve my problem. I am not able to find a good solution for my problem.

    Is there any way to speed up the process at ffmpeg decoder ?, is thre any other way to supress the overflows ?

  • Mjpeg text based subtitle extraction/replay

    2 décembre 2013, par user3058117

    I have an MJPEG based avi file that I cannot replay satisfactorily.

    The video I can correctly replay in FFPlay but i cannot replay or demux the text based subtitle stream.

    The file contains time/date stamps in the subtitles embedded as ascii text which i can see between the video packets (when viewed in a hex reader).

    FFmpeg cannot identify the subtitle codec b7t can see that there is a subtitle stream.

    Ive tried a number of filter combinations using GraphStudioNext. I found a couple of working solutions (when previewed in GraphStudio when served to avisynth the subtitles had disappeared again. I checked the filtergraph and the pin out from the avi splitter had misteriously disconnected. I cannot find a way out of this.

    Does anyone have any suggestions on how i might demux the subtitle stream(short of writing a converter to extract the text to srt based on the packet timing) ?

    This is my first post so apologies if i havent observed etiquette.

  • Fuent ffmpeg width inaccurate

    30 juillet 2023, par Vince

    


    Version information

    


      

    • fluent-ffmpeg version : 2.1.2

      • 


    • OS : Windows

      • 


    


    Code to reproduce

    


        ffmpeg()
      .input(pngPath)
      .inputOptions('-loop 1')
      .duration(OUTRO_DURATION)
      .videoFilters(`scale=${width}:${height},setsar=1`)
      .output(outroPath)
      .on('end', resolve)
      .on('error', reject)
      .run();


    


    (note : if the problem only happens with some inputs, include a link to such an input file)

    


    Expected results

    


    pngPath has a width of 420px, however no matter what the final output outroPath will have width of 408px. I have tried doing size('420x600') or videoFilters(scale=420:600,setsar=1) but nothing...

    


    Observed results

    


    The width is always 408px
