  • 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 error does not happen on all files but only on a handful of files.

    


  • Scrolling Effect of an Image using FFmpeg [closed]

    5 juin, par neeebzz

    I want to create an mp4 video of 40 seconds where an image just floats from top to bottom and vice versa.

    


    I am using the following ffmpeg command :

    


    ffmpeg 
    -loop 1 
    -t 40 
    -i ./input.jpg 
    -filter_complex [0]scale=800:-1[s0];[s0]crop=h=450:w=800:x=0:y=(ih-450)*(3*pow(t/40.241\,2) - 2*pow(t/40\,3))[s1];[s1]scale=800:400[s2] 
    -map [s2] 
    -pix_fmt yuv420p 
    -preset medium 
    -r 30 
    -vcodec libx264 
    ./output.mp4 -y


    


    The animation is working as expected however the motion is very jerky. How can I smooth it out ?

  • libavcodec.so.58 not found when running software compiled with opencv

    22 avril, par Abinaya

    I am using ubuntu 22.04. Now every time I try to run software compiled with Opencv, I get the following error :

    


    `libavcodec.so.58 => not found
 libavformat.so.58 => not found
 libavutil.so.56 => not found
 libswscale.so.5 => not found
`


    


    Looking around /lib/x86_64-linux-gnu/, I can find libavcodec.so.59, but not libavcodec.so.58.

    


    When trying to run sudo apt-get install libavcodec58, I get :

    


    Package 'libavcodec58' has no installation candidate

    


    I've scoured the internet in search of an answer, but could not find anything at this point. Any help with solving this problem will be very much appreciated.

    


    I have tried to recreate symbolic link with
'ls -l libavcodec.so.59'
1 root root 23 Aug 10 2024 libavcodec.so.59 ->libavcodec.so.59.37.100`

    


    'dconfig -vl libavcodec.so.59.37.100'
libavcodec.so.59 -> libavcodec.so.59.37.100`

    


    But I am still struck
