La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

Change the scale of overlay video based on audio level
26 janvier 2023, par DanHabibI'm looking to adjust the scale of my image overlay based on the input audio's loudness.


As the volume rises, I want to make it larger, as it gets quieter, I want to make it smaller.


I can't figure out how to access any relevant audio information in video filters.


I'm open to multi-step solutions but the result needs to be in sync

Video to Gif - Stretch to Scale
25 décembre 2022, par PhiloI have some videos that I want to turn into a gif.


When I use scale=800x600 on let's say as an example on a 1280x720 video. Instead of the gif being squashed into a 800x600 it just crops the video or just captured 800x600 of the 1280x720.


What code do I need to tell it squash itself into a 800x600 gif ? Normally it just turns the video into a 800x600 squashed if converted to a video but not working for the gif for some reason.
