  • 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.

  • Creating a transparent color mask that covers half of every frame in a video with opencv/moviepy/ffmpeg

    24 octobre 2019, par Nyktofob

    I’m doing a pose estimation in rats separated into two compartments of a cage. To make my tracking better I want to put a transparent color mask that covers half of every frame so that one of the rats will appear to the neural net as being of different color, thus making it easier for the net to differentiate those rats. My question is : Is there any easy way to do this using python (moviepy/opencv/ffmpeg) ?

    Bare in mind, I’m completely new to python, so I’d appreciate any recommendation of a tutorial or detailed answer.

    I tried using blender to do this, but failed miserably.

    I expect to be able to modify the video, so that there will be a rectangular transparent mask in some color that covers certain part of every frame (Let’s say video is 1920x1080 pixels, so from pixel 960 on x axis everything to the right is transparently green)

  • ffprobe : Use pixdesc API to provide color space names

    ffprobe : Use pixdesc API to provide color space names

    This API is more up-to-date, provides names compatible with filters
    
and external encoders, and is consistent with the other color
    
property variables.

  • How to add a color gradient to black and white in ffmpeg

    4 mai 2016, par Axiverse

    I’m converting a sequences of image files to video using ffmpeg. They are black and white representing a range of data. I want to apply a color gradient to the videos, something like black->white becomes black->red->orange->white.

    How do I do this with ffmpeg ?
