  • 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.

  • Improve ffmpeg CPU usage by compromising quality

    29 septembre 2016, par Hardik Juneja

    I am using FFMpeg for screen capturing.
    I am looking for a screen capturing tool that will run on 1000 of VMs (windows and mac).The VMs have limited CPU (1 core) and 2GB ram and No GPU.

    Currently I invoke ffmpeg with

    ffmpeg  -y -framerate 8 -f dshow -f gdigrab -i "desktop"  -c:v libx264  -crf 0 -preset ultrafast -threads 0 temp.mkv

    I am using gdigrab to capture screen ? Is there any better options that might reduce cpu usage ? or changing the encoder or format ?

    I am aiming for 4-5% reduction in CPU usage.

    Thanks in advance
