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 (...) -

FFMPEG - [WinError 2] The system cannot find the file specified
7 avril 2021, par Jules DanyI'm having an issue using the FFmpeg package.


Here's my code :


import ffmpeg_streaming

from ffmpeg_streaming import Formats, Bitrate, Representation, Size

_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))

hls = video.hls(Formats.h264())
hls.representations(_360p, _480p, _720p)
hls.output('C:/Users/juled/Videos/testStreaming')


Quite simple as you can see, found it on the web.


And here's the error message I have :

FileNotFoundError: [WinError 2] The system cannot find the file specified
</module>

I've been checking every file quoted in the error message, but only one of them is "my" code, the others are FFmpeg and Python libraries codes.


I'm using IDLEX for Python 3.7.6 on Windows by the way.


I've tried to change some of the FFmpeg library code, especially where subprocess.Popen appears, by putting a shell=True in the parameters. New Error Message, different this time.


I've added FFmpeg to the PATH, no change.


I've reinstalled FFmpeg to be sure, but no change. I'm using this version : python-ffmpeg-video-streaming-0.1.14.


Do any of you have a solution I could try ?


Oh and a friend has the same issue on MAC.

Finding file extension for media file using ffprobe
12 septembre 2013, par luddetI'm writing a media handling tool, using ffmpeg and ffprobe.
Part of the workflow consists of the application retreiving media files with nondescript extensionless file names.
Now I could get the extension from the media source but that would not fit as neatly into the program code flow, so I'm using ffprobe to extract the format information.The problem i have encountered is the format "QuickTime / MOV" where ffprobe gives me
format_name="mov,mp4,m4a,3gp,3g2,mj2"Is there a way to know which of the extensions is most appropriate ?
I guess the simplest solution is to pick the first,
mov, since that should work for all of them. But I would prefer to be more specific.Any way to accomplish this ?
