Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

Video Edit with FFMpeg
22 octobre 2020, par MaxI have been trying to figure out small video editing with FFmpeg in Android.


I want to make video to be stopped in some seek position with overlay for a few seconds.


For example, there is original video, and overlay image file.


After 3 seconds, the video will be looked as stopped with overlay for a few seconds (there will not be audio).
In a word, 5 seconds of video needs to be 8 seconds of video. (certain frame needs to be inserted with overlay for 3 seconds.)


How can I solve this with FFMpeg ? If anyone know FFMpeg command for this edit, please help me.

How can I overcome this key word error ?
4 answers
I’m trying to render a animation.ArtistAnimation object into a 24 fps video file in format mp4.
I have search about and I reached this. However, even after compiling ffmpeg I get this error message :
C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\Scripts\python.exe
"C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving Animation.py"
Traceback (most recent call last):
File "C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\lib\site-
packages\matplotlib\animation.py", line 161, in __getitem__
return self.avail[name]
KeyError: 'ffmpeg'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving
Animation.py", line 20, in <module>
FFMpegWriter = manimation.writers['ffmpeg']
File "C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\lib\site-
packages\matplotlib\animation.py", line 164, in __getitem__
'Requested MovieWriter ({}) not available'.format(name))
RuntimeError: Requested MovieWriter (ffmpeg) not available
Process finished with exit code 1
</module>What is the problem with ?
I would really appreciate if you can help me. Actually, if there is other ways to saving/render this kind of object into a video file (preferably mp4) I will be delighted to hear them.
Thank you very much

fftools/ffmpeg_enc : avoid breaking exactly integer timestamps in vsync code
28 mai 2023, par Anton Khirnovfftools/ffmpeg_enc : avoid breaking exactly integer timestamps in vsync code
The code will currently add a small offset to avoid exact midpoints, but
this can cause inexact results when a float timestamp is exactly
representable as an integer.Fixes off-by-one in the first frame duration in multiple FATE tests.
