Prérequis à l’installation
31 janvier 2010, parPréambule
Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

Layering 2 Audio Files at Set Times in Node.js
8 janvier 2017, par Tom RoweJust typed a massive question and realised I was wasting space and time, so I shortened it, will answer any questions of context if needed :
PROBLEM
I have a short audio file "name.mp3" and a long audio file "Vocals.mp3", and i’m trying to make an output file where the audio from "name.mp3" occurs multiple times over "Vocals.mp3"**.
For the sake of this thread lets just say every 20 seconds.
TRIED
So far I have been using "Fluent-ffmpeg" and have just started using "Sox-audio" but I’m open to suggestions of other packages. I have been able to split "Vocals.mp3" into parts and concatenate "Name.mp3" inbetween, but this has led to timing issues.
I have also been using the Mix() method from Sox but haven’t been able to find a working system of starting each "name.mp3" input at set times.
I’ll continue looking for more threads about this topic and if i find an answer i’ll share it here.
Cheers !

How can I make windows "like" the mp4 files I create in Linux and sync with Rsync
17 juillet 2019, par Geoff FoxI am a meteorologist on TV remotely from a studio I built. My control room uses a TriCaster, an amazing studio-in-a-box which runs on a Windows 7 variant. I make my weather maps myself on a Centos 7 machine — around 40,000/day.
I don’t entirely understand the problem, but here’s a quote from someone helping me at NewTek (the TriCaster company)
Rsync is built on a *nix based environment where all the file permissions and attributes are based on the Linux environment. There is no meaning for this in NTFS and Windows. The result is you get files that will most likely have the read-only flag set or no flag at all. Other attributes will be delivered as null. I’m sure from your own programming experience, programs don’t like null values and they generally have to be accounted for very specifically.
And so the finely tuned TriCaster stumbles, meaning lost frames or other problems caused by my short weather animations.
Here are some samples of the Rsync code I use
rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/conus*.mp4 /mnt/tricaster/Clips/Import
rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/nebraska*.mp4 /mnt/tricaster/Clips/Import
rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/northernplains*.mp4 /mnt/tricaster/Clips/ImportThese are mp4 files. They are only used locally. I really don’t care what flags are checked and permissions filled as long as Windows 7 doesn’t care.
At this point I always like to tell folks, though I do write some code my last computer class was in high school,’67-68 semester. Thanks in advance for your help.

Change AVI creation date with ffmpeg ?
1er novembre 2016, par brockAs far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.aviInstead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?
Command to edit the creation time :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi
