    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) (...)

  • FPV-Camera Input in Black and White / losses Color on conversion with FFMPEG [closed]

    22 décembre 2023, par LyffLyff

    so we're working on our end-of-school project and it's an FPV-Drone with an Analogue Camera on it. Plan is to send the video feed to a Raspberry Pi running an RTMP-Server from where a Phone-Application can view the live Video of the camera.

    


    To convert this analogue Data from the camera we use a USB2.0 Grabber (this one).

    


    To create the RTMP Stream from the converted USB-Input we use FFMPEG with the following command :

    


    


    fmpeg -f v4l2 -input_format yuyv422 -i /dev/video0 -c:v libx264 -crf 20 -preset ultrafast -b:v 2000k -fflags nobuffer -rtmp_live live -f flv rtmp ://192.168.8.107:554/live/stream

    


    


    It works fine, but the main problems at the moment are :

    


      

    • the video is in Black and White
B&W Image Stream

      • 


    • the stream has a delay of 10-20s depending on the network

      • 


    


    When I'm using the official Software provided by the Reseller I had the same problem, but as soon as it set PAL/BDGHI in the Settings the colour was shown correctly :

    


    Settings and Color Image in official software

    


    the video is in Black and White

    


    Does anyone know what settings there are to correctly decode the feed from the Camera and send the video with the colour over RTMP ? I don't know if this is the right place to ask this question, but I'm running out of ideas and every single decoder I have tried apart from the ones I'm currently using does not work.

    


    Any help is greatly appreciated :)

    


  • Can't get Accord-FFMPEG-Package working in my .NET-Core-Application

    6 août 2019, par FlixRo

    I have an ASP.NET-CORE 2.1-Application in which I am trying to use the Accord.Video.FFMPEG -Version 3.8.0-Package. I’ve tried to install it via NuGet-Package-Manager as well as via the Package-Manager-Console.(x64 AND normal Version)

    Installing works like a charm but as soon as I am trying to set the using-directives it does not work.

    using Accord.Video; works
    If I try this : using Accord.Video.FFMPEG; i get the following error.

    enter image description here

    .csproj-Files are set like this :

    enter image description here

    If set up for example a new VideoFileWriter there is no reference to the Accord-Package.

    Is there some incompatibility that I am missing ?

  • Using ffmpeg (or similar) to print detailed h264 information

    26 octobre 2012, par gimmeamilk

    I have some h264 video in mpeg transport stream, and I suspect at certain points in the video it switches from 1080i/50Hz to 1080p/25Hz. I'd like to prove that using some video analysis tool. Can ffmpeg (or similar) print out such detailed decoding info ? I've tried ffmpeg setting "-loglevel debug" but it prints no more info about the actual decoding.
