  • 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.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • How to compress video with uniform blur being the only side effect of compression ?

    5 janvier 2020, par Kukuster

    The point is to somehow compress a video file, significantly reducing bitrate but somehow without changing its apparent quality, and because it would fit the design, I thought I will blur the video. In raster image processing I guess, it would be closer to the mean blur, or kind of like being behind turbid glass effect.

    Ideally, I would like to be able to choose between compressing more with more strong blur and compressing less with less strong blur, all look pretty in any case.

    I tried some ffmpeg postprocessing libraries including fspp, spp, uspp (takes a long time to render), etc. I almost reached the goal using fspp with parameters 5:60:15. But blur was either very strong for certain objects or left other undesired artifacts. Although uspp does a good job and looks pretty, it leaves about half of the image in frames unblurred, while I’m looking for more uniform blur across the frame. Because sometimes it takes a lot of time, I didn’t try all the features of uspp.

    Here is my ffmpeg input data about the video streams :

      Duration : 00:01:03.02, start : 0.000000, bitrate : 4010 kb/s
    Stream #0:0(und) : Video : h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 3870 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)
    Metadata :
      handler_name : VideoHandler
    Stream #0:1(eng) : Audio : aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 133 kb/s (default)
    Metadata :

    Edit : example input and output :
    not blurred
    blurred
