Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement.

how to give random name to the file in ffmpeg
18 mars 2020, par amit9867How can i give random name to a output file in ffmpeg.
I want to give the filename as current date_time (ex.2020-3-18-10-13-4.mkv).
I don’t want to give a fix name such as output.mkv.

How can I add chapters to .mp4 files using a python script ? [duplicate]
7 mars 2023, par RandomIs there an easy way to add chapters (i.e. : sections with titles) to .mp4 files using a python script ?


For example, the script could process a 3-minutes video and label the first minute as "Beginning", the second minute as "Middle", and the last minute as "End".


The only solution (link) I stumbled upon so far involves using a ffmpeg command on the command line to extract the original ffmetadata from the video file before appending the chapters to it and updating the video with it.


However, I would like the process to be automated using a python script (instead of having to use the command line each time I have to process a video).
