  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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).

  • 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 :

  • 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

    • YUV422p compression

    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 ?
