  • 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.

  • 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 :

  • 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
