Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
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. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

How to export audio from a iPhone video file with FFmpeg ?
11 janvier 2020, par DanScripterUPDATE 1 the problem resides in the input read-stream. (check below)
I am using fluent-ffmpeg (version : 2.1.2) to get a .mp3 file out of a video file that I input as a stream .createReadStream(). I output the file as a .pipe to a remoteWriteStream.
ffmpeg -i pipe:0 -vn -f mp3 -acodec mp3 -movflags frag_keyframe+empty_moov pipe:1
This works fine with .mp4, .webm and .mov (codec : prores) files.
But it somehow does not want to work with a .mov out of an iPhone 11. FFmpeg is not giving me any error when running above code. It creates the .mp3 file but the size is just 152 B and it is not playable.
I ffprobed the iPhone .mov files it returns this :

I already tried to take the .mov re-encode it to an .mp4 via ffmpeg and then try the above code to get the .mp3 - still does not work.
Any advice how I can make this work ?
thanks !
UPDATE 1
The problem resides in the input stream ! When I download the file to the local machine and input it as as a local file, not as a read stream, it works perfectly.I am creating the stream from a google cloud bucket like this :
const myBucket = storage.bucket('myBucket');
const remoteReadStream = myBucket.file(file).createReadStream();Since this code is perfectly working with all other codecs, what maybe the issue while creating the read stream from the google cloud from a h265 file ?

FFMPEG change audio channel tag for MOV file
7 mars 2016, par Daniil ShevelevI am having difficulty renaming audio stream on MOV (works fine on MP4).
As you can see during the run it shows expected result - audio stream 2 labelled as ’div’, but when I check using ffprobe all the streams are labelled ’eng’.
Below is the code that I use.PS C:\Tools\ffmpeg-20160224-git-10fa50c-win64-static\bin> .\ffmpeg.exe -i C:\Users\dan\Downloads\IceRoadDVTest2.mov -vcodec copy -acodec copy -map 0:v:0 -map 0:a:0 -map 0:a:1 -metadata:s:a:1 language=div -qp 0 TEST2_copy.mov
