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.

Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Automated installation script of MediaSPIP

swresample/rematrix : treat 22.2 as 5.1 (back) when mixing
1er août 2020, par Jan Ekströmswresample/rematrix : treat 22.2 as 5.1 (back) when mixing
Only this sub-set of channels actually follows the bit mask order
in the official 22.2 channel mapping. Additionally, the 5.1 channels
are there for backwards compatibility with the previous system.This enables the utilization of 22.2 content until a proper down/up
matrix is added into swresample. -
ffmpeg make video from multiple images and one audio with specific timestamps for each image [closed]
2 juin 2024, par TrojoshI have an audio file and I have 15 images. I would like to make a video from these 15 still images. Each image may appear for different number of seconds.
E.g. Image 1,2,3 will take 3 seconds each but image 4 may take 40 seconds because it is more complex.


How can I use ffmpeg to specify timestamp for each image and add audio to the same.


Also note that the sum of timestamps of all images = running time of the audio.


I looked at this question and image2 filter option from the official documentation but no luck in producing such a video

Limit file size in FFmpeg
26 novembre 2019, par AreteThe official documentation for FFmpeg says :
-fs limit_size (output)
Set the file size limit, expressed in bytes. No further chunk of bytes is written after the limit is exceeded. The size of the output file is slightly more than the requested file size.
This is very confusing. If the file size is slightly more than the requested file size then I have the following questions :
-
What determines how much more (than the requested file size) the file will consume ?
-
How much more will the file exceed the requested file size ?
-
Is there any way to set the file size exactly ?
-
What is the point of having the
-fs
if it does not actually work ?
