  • 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.

  • How Akamei is packaging HLS and DASH videos ?

    27 décembre 2022, par Ahmed Mahmoud

    Latlert I've been trying to create my own simple streaming service which converts an mp4 video to HLS or DASH. For the sake of simplicity, let's focus on only HLS.

    &#xA;

    Apple is the the one how created HLS (HTTP Live Streaming) which consists of a different resulotions playlist files, and each file consists of seperate sepemts (ts, mp4 or m4a) each segment is a time range of the original video.

    &#xA;

    I've noticed the Akamei are using the same mp4 video and a query param range to range over the video segements.

    &#xA;

    Example of a typical segments playlist :

    &#xA;

    #EXTM3U&#xA;#EXT-X-TARGETDURATION:6&#xA;#EXT-X-VERSION:3&#xA;#EXT-X-MEDIA-SEQUENCE:1&#xA;#EXT-X-INDEPENDENT-SEGMENTS&#xA;#EXTINF:6.92,&#xA;240p_noaudio_dash1.ts&#xA;&#xA;#EXT-X-ENDLIST&#xA;

    &#xA;

    Example of Akamei playlist :

    &#xA;

    #EXTM3U&#xA;#EXT-X-VERSION:6&#xA;#EXT-X-MEDIA-SEQUENCE:0&#xA;#EXT-X-TARGETDURATION:6&#xA;#EXT-X-PLAYLIST-TYPE:VOD&#xA;#EXT-X-MAP:URI="../../../parcel/video/78619exa.mp4?r=dXMtd2VzdDE%3D&amp;range=0-830"&#xA;#EXTINF:6.066667&#xA;../../../parcel/video/78619exa.mp4?r=dXMtd2VzdDE%3D&amp;range=5975-2400598&#xA;#EXTINF:6.066667&#xA;../../../parcel/video/78619exa.mp4?r=dXMtd2VzdDE%3D&amp;range=2400599-4512749&#xA;#EXTINF:6.033333&#xA;../../../parcel/video/78619exa.mp4?r=dXMtd2VzdDE%3D&amp;range=4512750-6575755&#xA;#EXTINF:6.066667&#xA;../../../parcel/video/78619exa.mp4?r=dXMtd2VzdDE%3D&amp;range=6575756-8651671&#xA;#EXT-X-ENDLIST&#xA;

    &#xA;

    How Akamei is gementing the same video on the fly to stream HLS and DASH ?

    &#xA;

    I searched and read the HLS Specifications with no luck.

    movenc : Add support for writing sidx atoms for DASH segments

    A flag "dash" is added, which enables the necessary flags for
    
creating DASH compatible fragments.
    

    When this is enabled, one sidx atom is written for each track
    
before every moof atom.
