Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

FFMPEG - Why can't i record a video for more than 10 seconds ?
12 février 2020, par gabrielI’m developing a screen recorder for windows with python but for some reason i can’t record the video for more than 10 seconds.However i can record the audio for more than 10 seconds.
Also i’m using :FFMPEG - to record the video with mp4 extension
PYAUDIO - to record the sound
TKINTER - to design the GUI
Since the problem is with the video recording i will leave the code that i used with ffmpeg :
"""
cmdGen.py generates ffmpeg commands to record your screen
"""

FFMPEG - How to pipe RMS_level and pts_time metadata without generating unwanted metadata
6 février 2020, par Tovi NewmanI am trying to find the loudest (highest rms_level) moment in an audio file, but I need to pipe the metadata rather than write to a file.
I converted the answer found here : [https://superuser.com/questions/1183663/determining-audio-level-peaks-with-ffmpeg][1]
By removing the write to file command and adding a pipe.
Here’s what I’ve got.ffmpeg -i loudSoft.mp3 -af astats=metadata=1:reset=1,ametadata=print:key=lavfi.astats.Overall.RMS_level -f null - 2> result.txt
The only problem is, now I’ve got a lot of unwanted metadata before and after the RMS_level and pts_time data as well as
[Parsed_ametadata_1 @ 0x7f9d42c37500]
being printed on each line. None of that was being written when I was writing to a file instead of piping. (all I need is the time and the rms.)Here is an abridged version of what I get when I write to file :
