  • 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" (...)

    On ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...
    La liste suivante correspond à des logiciels qui tendent peu ou prou à faire comme MediaSPIP ou que MediaSPIP tente peu ou prou à faire pareil, peu importe ...
    On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • Not able to Receive Exact Data over UDP

    20 juin 2016, par Prasanth Kumar Arisetti

    I am transferring the data over udp using below pipeline,

    gst-launch-1.0 videotestsrc ! videoconvert ! x264enc ! mpegtsmux ! rtpmp2tpay ! udpsink host=192.168.1.139 port=8090

    And receiving the data by using below pipeline,

    gst-launch-1.0 udpsrc port=8090 ! tsdemux ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink

    The Problem is,

    Until a moment, i am getting the data exactly, but after few seconds,

    The whole window is becoming in greem color,Green Colored Screen

    But Sometimes, getting the data correctly, but sometimes, i am getting the green screen. What is the Problem Here ? And how to resolve it ? And Why it is happening like that ?

  • encode x264(libx264) raw yuv frame data

    12 janvier, par Mohamed El-Sayed

    I am trying to encode an MP4 video using raw YUV frames data, but I am not sure how can I fill the plane data (preferably without using other libraries like ffmpeg)

    



    The frame data is already encoded in I420, and does not need conversion.

    



    Here is what I am trying to do :

    



    const char *frameData = /* Raw frame data */;

x264_t *encoder = x264_encoder_open(&param);
x264_picture_t imgInput, imgOutput;
x264_picture_alloc(&imgInput, X264_CSP_I420, width, height);

// how can I fill the struct data of imgInput

x264_nal_t *nals;
int i_nals;
int frameSize = x264_encoder_encode(encoder, &nals, &i_nals, &imgInput, &imgOutput);


    



    The equivalent command line that I have found is :

    



     x264 --output video.mp4 --fps 15 --input-res 1280x800 imgdata_01.raw 


    



    But I could not figure out how the app does it.

    



    Thanks.
