  • 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.

  • Ffmpeg rounds seconds instead of using the milliseconds part

    10 mai 2021, par NourElDineA

    I tried to cut a video using the following command :

    


    ffmpeg -i input.mp4 -ss 00:00:00 -to 00:00:06.600 output.mp4


    


    When I run the command ffmpeg rounds up and the output video is 7 seconds instead of 6.6 seconds.
I would like to know if there is a way to cut the video precisely where I tell it to.

    


    Here is the log file content :

    Then, I try to use mpv to play the video. I use the command mpv test.mp4, and it successfully play the video. There are detailed logs.

    


    $mpv test.mp4

    I don’t know much about video encoding and decoding. Both mpv and ffplay use ffmpeg for video decoding, but why are the results different ?
Thanks in advance.
