The proper way to limit framerate when recording screen on macOS
5 juillet 2024, par jsxmacOS 14.5, FFmpeg 7.0.1. To record the screen, if I use the code from Wiki, that is,


ffmpeg -f avfoundation -i 1 output.mp4



the frame rate seems to be so high that when I press
q
to stop recording, the following message persists until my MacBook Pro starts to noise by its cooler : "[q] command received. Exiting."

My current solution is to add
-r
after-i
:

ffmpeg -f avfoundation -i 1 -r 24 output.mp4



But I heard that a more correct solution is to replace
-r
with-framerate
and to put it before instead of after-i
:



ffmpeg -f avfoundation -framerate 24 -i 1 output.mp4



Note that I used
-framerate
as an input option instead of-r 24
as an output option, so I'm telling avfoundation to record at 24fps instead of recording at the default fps and then forcing FFmpeg to drop or duplicate frames to give you the desired 24.



This doesn't work for me currently, and appears to be the same as I don't use
-r
at all.

And so, what is the proper way to fix the "too high framerate" issue when recording the screen on macOS ? Do we need
-r
or instead-framerate
, and where to put it, before or after-i
?

Just in case, here is the log of
ffmpeg -f avfoundation -i 1 output.mp4 -v verbose

Evolution #4573 (Nouveau) : Enlever Jquery UI du Core
13 octobre 2020Jquery UI (https://jqueryui.com/) n’a plus d’activité maintenue (en tout cas aucune release depuis 4 ans maintenant).
Il serait opportun de supprimer jQuery_UI du core, et de le remplacer par des librairies spécifiques pour les besoins identifiés.
Tout d’abord l’usage dans le Core.¶
Je crois que l’on utilise :
le dateur
À remplacer par https://duetds.github.io/date-picker/ ?
Voir également la discussion sur Saisies : https://git.spip.net/spip-contrib-extensions/saisies/issues/43le sortable
À remplacer par https://sortablejs.github.io/sortablejs/ ?
D’autres plugins s’appuient sur d’autres éléments le jQuery-UI :¶
- Accordéons et Tabs (Fabrique)
- Une extension picker multidate (Agenda)
- ...Dans un premier temps, il « suffit » qu’ils mettent le plugin jQueryUi actuel en dépendance...
Dans un second temps... trouver des alternatives adaptées... et faire en sorte qu’elles soient partageables entre différents plugins si besoin.Sur le partageables¶
Il pourrait y avoir un plugin du core regroupant des librairies js utilisées régulièrement, comme le faisait le plugin jquery-ui, mais avec différentes librairies plus indépendantes.
Pourquoi pas. Plutôt que de faire N petits plugins JS. -
Save Slow motion video with ffmpeg on android devices
25 mars 2017, par nkalra0123I want to save videos in slow motion through my android app.I tried to convert videos into slow motion by changing frame rate.
I used the following commands,first command is dumping 30 frames per second from videos to a temp directory, and then second command is using these images to create a video with reduced or faster frame rate and then i am deleting all the images from temp directory.
ffmpeg -i input_file.mp4 -r 30/1 img%03d.png
ffmpeg -framerate 15/1 -i img%03d.png -r 30 -pix_fmt yuv420p out4.mp4But this is a very slow operation. It is taking like forever even for small videos.
I even tried to change PTS(presentation time stamp) of videos, but it is not working properly on android phones
using this command :ffmpeg -i input.mkv -filter:v "setpts=2.0*PTS" output.mkv
as suggested here :
https://trac.ffmpeg.org/wiki/How%20to%20speed%20up%20/%20slow%20down%20a%20videoCan anybody suggest me how can i make it fast. Is it necessary to save frames to a temp directory, can i pass the output of ffmpeg process to another ffmpeg process executing concurrently through some method.
Is there any other ffmpeg command to save the videos in slow motion ?
