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" (...)

JPEG quality problems
26 février 2020, par atokzzI am currently using C# to retrieve frames from a borescope (via the FFMPEG library). However, I came across a problem weeks ago and I can’t solve it.
The images are returned in JPEG format (since the borescope stream is MJPEG).
Some images come without quality problems, but others come with a strange line in the middle
followed by random staining. (At the end of the question there is an example of a normal image and one with problems).Analyzing the structure of the files, I realized that there are some differences, but I don’t really understand JPEG’s binary structure very well, and I can’t tell what is corrupted.
Getting to know what is corrupted in the image, which culminates in the quality problem, is very important to me because, through this, I can discard the frame using C#. However, without understanding this problem, I can’t even discard the frame, much less fix it.
So, having the image without quality problems as a reference, what is the problem with the binary structure of the image with quality problems ?
Examples :
JPEG 1 : Image without quality problems
Image’s preview (just to see the quality, do not download from here)
JPEG 2 : Image with quality problems
Image’s preview (just to see the quality, do not download from here)
It’s possible to look into binary structure of images through online HEX editors like : Online hex editor, Hexed or Hex-works.
Thank you for reading and have a nice day.

Can you crop a photo to fit a circle using ffmpeg ?
11 septembre 2021, par L04DB4L4NC3RI know that ffmpeg is very advanced and can be used to crop both photos and videos in order to rescale them. Bit mostly everything I've come across online uses the X and Y coordinates to crop a photo in ffmpeg. How can we use this to crop a photo in the form of a circle rather than a rectangle ?

Using FFMPEG to automatically set a single max filesize across multiple different sized files
14 juin 2020, par DuffCreeperI don't really know how to word it any better but I'm trying to convert WEBM/GIF to MP4 with no sound



The problem I'm facing is retaining the quality without having to sacrifice it across multiple files by having to resize them to 420p



The idea was to hopefully somehow get FFMPEG to automatically determine the bitrate required for the file to hit the filesize of 10mb. Though I have looked everywhere online and I have not found a single answer regarding it, so either it's not possible or I'm blind
