Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.

Using python and ffmpeg to split .mp4 video into chunks of few seconds
3 juin 2022, par PalmI would like to split videos into small chunks of two seconds while maintaining good quality and running fast.


I've tried various techniques on StackOverflow such as


- 

- Using Python script to cut long videos into chunks in FFMPEG
- Cut .mp4 in pieces Python
- python library for splitting video
- How do you split a list into evenly sized chunks ?
- ...












But the result does not satisfy me. Some are too slow, and some do not give the short-length chunk.

vp9 : use superframe split BSF
17 novembre 2017, par wm4vp9 : use superframe split BSF
webm usually has invisible superframes merged with normal frames.
(vpxenc muxes them in this form, which is evidence enough that this is
the standard webm packet format. It's rather unclear whether ffmpeg is
even allowed to remux them with split packets.)The vp9 decoder needs them to be in separate packets for multithreading
to work. Add the BSF to the decoder, so the conversion happens
automatically.This contains the important part of fa1749dd34c55fb9, which
was apparently skipped in commit d417e95af76. This restores Libav API
compatibility. -
ffmpeg Split And Zoom
4 décembre 2019, par megaimd megaffmpeg -i video.mp4 -c:v libx264 -crf 22 -map 0 -segment_time 3 -reset_timestamps 1 -g 10 -sc_threshold 0 -force_key_frames “expr:gte(t,n_forced*3)” -f segment out/output%03d.mp4
As you can see, it is saved :
output1.mp4
output2.mp4
output3.mp4
output4.mp4and so on, it split every 3 seconds.
Ho can I make, for exempleoutput1.mp4 zoom 2X
output2.mp4 Normal
output3.mp4 zoom 2X
output4.mp4 Normalfor one movie to zoom in and for another to not zoom
