  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • vf_colorspace : Add support for full range yuv

    vf_colorspace : Add support for full range yuv

    Whenever a full range video is input, since the YUVJ* formats are not
    
listed as supported for this filter, a range reduction takes place
    
through the auto-inserted format filter, forcing the conversion to
    
operate on a limited range,
    

    However the filter handles full range videos perfectly fine, so adding
    
support to YUVJ* formats will allow skipping a conversion step, while
    
providing completely identical results.

  • Raw extraction of frames from a movie

    29 septembre 2016, par vkubicki

    I would like to extract images from a grayscale mj2 movie. Each pixel is encoded using 16 bits. Since this is a technical movie, I need to extract the value at each pixel without processing, as those values linearly map to a physical quantity (a heatmap from an infrared camera). I am using Scala, and I do not find any suitable solution for a direct extraction (either in Scala or in Java, but I am a beginner). Therefore I intend to use ffmpeg to extract individual frames on the disk, then load them as BufferedImage in Scala and process them.

    Is this a good approach ? Which format should I use to avoid any transformation in the data ? I want each extracted frame to ba as "raw" as possible ? Is it possible to directly output a csv containing the aforementionned values ?
