  • 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" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to process video stream ?

    27 avril 2016, par sharpener

    I would like to ask some experienced multimedia professional how to proceed with following task :

    Given URL provides video stream and we would like to get access to decoded frames (byte stream in memory) in managed Win7+ application (C#). We don’t want to render/present the frames the standard way. The video format is known but not fixed (might get changed between two successive sessions, but we will know the parameters).

    So far, I have found there are several methods and I have build following picture in my mind :

    1. ffmpeg wrapper
      • Pros
        1. Self contained (no dependency to windows technologies)
        2. Powerful
      • Cons
        1. Little more complex to understand
        2. Lot of different wrapping variants (FFmpeg.NET, ffmpeg-sharp, ffmpeg-shard, FFmpeg.AutoGen, ...)
    2. DirectShow wrapper
      • Pros
        1. Widely used/supported technology (variaous filters freely available)
        2. Nice/detailed documentation on MSDN
      • Cons
        1. Quite old
        2. Considered obsolete from the point of author’s view (available only for desktop model on runtime >= Win8)
    3. MediaFoundation wrapper
      • Pros
        1. Theoretical successor of DirectShow, so should be available in the future
      • Cons
        1. Seems to be not as good as DirectShow
        2. Not very popular, limited "community" support
    4. FFmpegInterop wrapper
      • Pros
        1. Microsoft’s open source wrapper alternative
      • Cons
        1. Not available for runtime < Win8
  • ffmpeg : how to stream from rtmp to FLS ?

    21 juin 2016, par yarek

    I can create HLS from static MPEG4 using that command :

    ffmpeg -i video.mp4 -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    I am now trying to achieve that :

    live RTMP(FME)------->FFMEG-------------->HLS

    enter image description here

    I tried with :

    ffmpeg -i rtmp://127.0.0.1:1935/live/video -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    But got error :

    Closing connection : NetStream.Play.StreamNotFound
    rtmp ://127.0.0.1:1935/live/video : Unknown error occurred

    Any idea how to achieve :

    RTMP---->FMPEG----->HLS ?

    I also tried :

    ffmpeg -i "rtmp://localhost:1935/live/yarek live=1" -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    Seems better but stucks :
