Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

python suggests ffmpeg installation when it is installed
17 janvier 2021, par FNTEI have a problem related to the bar_chart_race python package. I have installed ffmpeg but when I execute my code, I get :


You do not have ffmpeg installed on your machine. 
Download from here: https://www.ffmpeg.org/download.html.



I know that I have used this package before and it was all good. I have installed ffmpeg version :


ffmpeg -version
ffmpeg version 4.2.3 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 9.3.1 (GCC) 20200523



Do you know what I can do ? I have bin folder in path.

ffmpeg export without color loss
27 décembre 2020, par serI'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?


Currently, I use this code :


./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "



I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)


I also get this error when I run ffpmeg :


[swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly



See Image comparison here — the blacks on the export were not as "black" as original
