  • 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

  • How to switch content of ffmpeg rtmp stream whilst streaming continues ?

    9 juin 2020, par re0603

    I am currently re-streaming an online stream to my server - using RTMP.

    &#xA;&#xA;

    There is another online stream that I also want to re-stream to the same RTMP destination, when certain events occur.

    &#xA;&#xA;

    How do I programatically switch the content of the stream without ending the RTMP stream of the first source ? I do not want the stream to go offline whilst I switch content.

  • What is the point of encrypting HLS files ?

    29 janvier 2016, par APITC

    I am currently working on a project of videos on demand where I convert videos to HLS using FFMPEG.

    Videos are publicly hosted on AWS S3 and there is an API giving the URL of the HLS playlist.

    Now, I was looking at encrypting HLS files with AES-128 so that people can’t download and watch the video offline.
    I found the procedure which consists in hosting the key online and using that key while converting the video to encrypt the segments.

    The URL of the key is written in the HLS playlist, and the file is publicly available online.

    So anyone has access to the encryption key.

    I don’t understand what is the point of encrypting the segments if anyone has access to the key.

    Can someone enlighten me ? I know I must be missing something. Thanks !
