  • 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 (...)

  • Inappropriate ioctl for device in zoneminder - zmc_dvideo0

    9 juin 2024, par Adam

    I recently needed to rebuild my zoneminder local camera system, running on an RPi. I switched OS from Debian to Ubuntu and now I'm struggling to get video4linux to decode the video input. The result is either a black or green screen depending on the compression palette I select.

    


    I'm using /dev/video0 as my input.

    


    v4l2-ctl --list-devices

unicam (platform:fe801000.csi):
        /dev/video0
        /dev/media3


    


    In the logs I'm getting :

    


    zmc_dvideo0 10907   ERR Unable to query control: Inappropriate ioctl for device 


    


    I don't understand the function of the /dev/media3 device, presumably created by the bcm2835-v4l2 module. This site suggests that /dev/video0 needs to extract the ioctl from or link in some way to /dev/media3. Perhaps a red herring.

    


    If I select /dev/media3 as the source, I get :

    


    : FAT [zmc_dmedia3] [Failed to query video device: Inappropriate ioctl for device]
: ERR ['zmc -d /dev/media3' exited abnormally, exit status 255]


    


    I'm using

    Using ffmpeg from the cli, I get a similar output, resulting in a green display. This happens both with and without the hardware acceleration flag.

    I've set debug to 6 in the ZM options - Any clues on troublshooting steps I can take to further understand why the camera stream is not being shown and how to fix it ?

    


  • Index error with moviepy when running on aws

    29 avril 2024, par Hardik Patel

    I am getting this error :
"MoviePy error : failed to read the duration of file %s.\n"
OSError : MoviePy error : failed to read the duration of file https://delivery.gettyimages.com/downloads/1490392845?k=20&e=AnE-X_nyTRBG5QvUm1OnnCZEOURkdWAdDeQJTmDW8Eo41FL7u_ROCopEha5N-Kwh-fxBr44QIe5s2vzAUchlcVs91TwSlJTMOKWYSTraamKCPRcJv19CqNZRB_FgLaW_.

    


    The funny thing is that for the same line of code :

    


    video_duration = VideoFileClip(getty_url).duration


    


    when running on my mac, it is running fine. However when running from an aws server I am getting this error :

    I checked the version of my package on both mac and aws, the packages are the same. Went through different stackover flow solutions but non of them totally aligns with my issue.

    


  • Why ffmpeg concat results wrong fps ? How to avoid it ?

    29 avril 2024, par Jinglong

    I have several mp4 video files and want to concat there video streams into a new mp4 file. The command I used shows below :

    


    ffmpeg -f concat -safe 0 -i concat.txt -an -c:v copy -y out.mp4


    


    The fps of result does not meet expectations.

    


    For example, there are two input wrote in concat.txt :

    


    file temp_result_0.mp4
file temp_result_1.mp4


    


    




    


    


    


    


    


    


    


    



    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    file duration number of frames fps tbr
    temp_result_0.mp4 60.0 1200 20 20
    temp_result_0.mp4 0.1 2 20 20
    out.mp4 60.1 1202 19.97 20

    


    The out.mp4 has correct duration, nb_frames but wrong avg_frame_rate (expecting 20 but get 6010/301).
