  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • FFmpeg parameters for Fisheye image correction

    19 janvier 2023, par Julio Cesar

    I am trying to achieve two things (any of them will work for my solution) :

    


      

    1. Fisheye video to equirectangular (and view it in 360 view)

      2. 


    2. Fisheye video to flat (if I understood correctly, it will be just like the fisheye image (maybe I will lose some FoV ?) but without distortions. Of course in this case I will not use 360 view).

      3. 


    


    Camera specs : https://documentation.meraki.com/MV/Viewing_Video/Understanding_Image_Quality_on_the_MV32

    


    For test purposes I am using an image as input :

    


    For 1), I am using ffmpeg -i input_file -vf v360=fisheye:e:ih_fov=180:iv_fov=180:pitch=90 output_file. This command gives me a rectangular image where the half upper is black, and when testing in https://renderstuff.com/tools/360-panorama-web-viewer/ the user can navigate through this black space (I would like to limit user view, so he could not get to the black part). If I crop and remove the black part, the image in the 360 view becomes distorted (loses the aspect ratio).

    


    For 2), I tried ffmpeg -i input_file -vf v360=fisheye:flat:ih_fov=180:iv_fov=180 output_file but it doesn't seem to correct the distortions properly.

    


    FYI this video will be published in AntMedia server to be used as an iframe in web applications. I'll try to use 1) in AntMedia since it supports 360 view (https://antmedia.io/play-live-360-degree-video/).

    


    Since I am new to this, please ask for more information if needed.
    
Thanks in advance.

    


  • Streaming Installation paid request [on hold]

    9 février 2016, par Lewis Tyler

    Basically I need a streaming platform which allows my users to broadcast their webcam to a rtmp ip each users would have there own link rtmp://192.168.0.1/username/token I just need the server ip. No installation required. Does anyone know of any good sites to purchase a streaming server like this ? Or can anyone set one up for me over team viewer on my own remote server, happily to pay someone for their time.
