  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.
    The code of this (...)

  • Live video streaming with Node js ,HTML5, MPEG-DASH, FFMPEG and IP camera/Raspberry Pi

    12 mai 2016, par sparks

    I am a programmer but i am very new in live video streaming concepts.I need help

    What i want to accomplish

    I want to develop an online live video streaming system.The scenario is i would have a device or number of devices(raspberry pi & camera only OR ip camera only ...not sure yet) to capture the video and stream the video live in real time remotely to my web app.Multiple clients can connect to the web app and watch the video live.The key things to note here, is that these devices should be wireless(able to connect to internet and live stream the content) and also i want to eliminate the idea of manually configuring the ip adrress to local WIFI router.So simply i turn on the device and it start streaming right away to the web app.

    Infrastructure, Platforms,Browsers, Streaming methods and formats

    In the beginning i just want to stream though chrome web browser(that’s all i care about).But in the future i would build android and IOS mobile apps.So long term i would expect to be Chrome and mobile(Android & IOS platforms)
    So based on my research i learned that the client should be HTML5, streaming method MPEG-DASH(In the future add HLS), the web app will be in Node Js.I also came across Dash.js for Html5.

    My understanding of streaming based on my research

    I also came across things like FFMPEG,Dash encoder and wowza which i am not clear about.Now correct me if i am wrong, my understanding is that FFMPEG get hold of the device/camera and the content(i am not sure the format of the content at this point)and format it(i am not sure what this means in simple english) and then Dash encoder picks up and re-format the content to MPEG-DASH format, which produces MPD and then Dash.js client uses MPD to display the video to the browser.

    QUESTIONS

    1. First correct me if i am wrong based on my understanding above or
      clarify for me.Also I am not sure of where the wowza streaming
      engine come into play. Do i even need it ?

    2. I am not sure of the devices to use between Raspberry pi with camera
      module/ Or IP Wifi camera by itself.I know with raspberry pi
      connected to internet you can set up all the necessary programs and
      stream the video to web app directly(not sure about quality and
      performance) but I am not sure about Wifi camera.Is it possible to
      connect to the wifi camera remotely from the web app programatically
      without opening the wifi router portal manually or i should stick
      with Raspbery Pi ?

    3. For raspberry Pi would i be able to connect it with high quality
      picture IP camera/web cam ? (The point here to get the best picture
      through raspbery Pi)

      My expectations

      Better performance and quality would be great.But i know live streaming is not easy so i am willing to compromise performance to a point but not quality.

    Thank you in advance, Anything will be appreciated.I know this is a lot so take your time :)

    libavformat/dashdec : Fix issue with dash on Windows

    Use xmlFree instead of av_freep
    

    snip from libxml2 :
    

     * xmlGetProp :
    
...
    
 * Returns the attribute value or NULL if not found.
    
 *     It's up to the caller to free the memory with xmlFree().
    

    According to libxml2, you are supposed to use xmlFree instead of free
    
on the pointer returned by it, and also using av_freep on Windows will
    
call _aligned_free instead of normal free, causing _aligned_free to raise
    
SIGTRAP and crashing ffmpeg and ffplay.
