  • 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.

  • Understanding CPU usage in linux using "top" command for VLC usage

    25 octobre 2014, par user3130013

    I have 2 quad core processors and I cant seem to understand what "top" is telling me.

    I run a VLC transcoding application and i currently transcode 8 streams and "top" shows me that I am using 200% of my CPU. Now for a Pentium 3 that would be horribly bad but I dont understand how Linux calculates CPU usage with multi core processors.

    Does this mean that my both processors are utilized 100% ? 2 cores at 100% ?

    I also ran ffmpeg application for the same purpose and I could run 8 instances at 90% each which seemed to me like each processoss would occupy 1 core.

    VLC has much lower CPU usage footprint so I just want to make sure I am not killing the hardware.

  • how to restream rtsp h264 as "live dvr" for iOs using ffserver ?

    18 mai 2017, par mojovski

    I would like to grab an existing stream from an IP-Camera delivering h264 encoded rtsp stream and restream it for iPhone/Ipad, where the user would have the opportunity to jump back in time for aprox. 1 minute. And later jump back to the "live" feed.

    Actually I would like to do the same as in wowza (http://www.wowza.com/addons/wowza-ndvr-addon) but with ff** software.

    Thank you for all your hints !
