  • 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" (...)

  • Does ffmpeg support dynamically reconfigure filter graph now ?

    3 août 2020, par Bingo

    I am using ffmpeg C API to develop some video mix program, and I use ffmpeg scale, crop and overlay filter to implement this. My program works well when the input video's resolution keep unchanged. But my input video stream does change resolution frequently. Currently I handle the resolution change by destroying the filter graph and then rebuilding it, but I don't think frequently destroying and rebuilding filter graph is a good idea because it takes time to do this process.

    


    So I wonder if there is any already implemented feature in ffmpeg that can dynamically reconfigure video resolution of the filter graph.

    


    I have done some google search and find some discussion on this feature. Here is the related disscution :
https://ffmpeg.org/pipermail/libav-user/2012-October/002920.html
    
http://ffmpeg.org/pipermail/ffmpeg-devel/2012-October/133012.html

    


    But I can't find out any conclusion of this feature.

    


    Does anyone has any idea ?

    


  • How to test packet loss and recovery features of Secure Reliable Transport Protocol

    26 novembre 2019, par aramok

    I am using h264 encode method with ffmpeg and I am able to stream it with UDP Protocol. Without packet loss video quality is good. Since UDP Protocol does not guarantee packet reliability , I implemented Haivision’s Secure Reliable Transport (SRT) protocol on top of UDP Protocol.

    Before that I tested UDP Protocol with dropping some percentage of packets intentionally by writing simple program and video stream results were not that good.Since I am using h264 , losing packets effects video quality rapidly. Now I am using SRT Protocol on top of UDP Protocol. SRT Protocol also use UDP Protocol but it has packet recovery feature for live video streams. I want to test it’s packet drop recovery feature and see the results.

    How can i do that programmatically or with any tools ?

  • how to call avconv via shell_ exec in php ?

    8 janvier 2018, par Blurry Script

    when I call a command to convert video from console linux its all working, but when I call the same command from shell_exec in php, it gives no errors it returns nothing.

    even tough I added sudo 2>&1 to redirect the output, for example this command :

    $res = shell_exec("avconv -i film.mkv 2>&1");
    
echo $res //nothing
    
exit;
