  • 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.

    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

  • Recreate image with ffmpeg safe ?

    28 février 2019, par John

    I want to use ffmpeg to recreate an image file that is uploaded. I know that in PHP you can use imagecreatefromjpeg, imagecreatefrompng and imagejpeg etc. to recreate images. That way, if there is any hidden malware in the original images, it will ’break’ / be mangled.

    But I want to use this ffmpeg command to recreate image files :
    ffmpeg -i in.jpg out.jpg
    I have tested converting an image file that has PHP code stored in its EXIF field, and after converting it, the PHP code is no longer executed in the converted file..

    Also, the converted file is smaller in size : from 45.9 KB to 11 KB..

    Is that a safe way ?

    EDIT
    Btw, I am also checking the MIME type etc, but MIME can be forged, hence recreating image files is recommended.. I want to convert files on another server where there is no PHP installed. That way I can also avoid any potential PHP memory issues.

  • Converting image sequence to video with inconsistent frame rate

    4 novembre 2022, par George

    I recently collected video data where the video was generated as image sequences. However, between different video of the same length, different numbers of frames were acquired, which made me think that the image sequence have varied frame rates between videos. So my question is how do I convert this image sequence back to video with accurate duration between frames. Is there a way to get that information from the date and time it was created using a code ? I know ffmpeg seems to be the tools many people use.

    


    I am not sure where to start. I am not very familiar with coding, so already have trouble executing the correct codes.
