• Evolution #4798 : Suppression des mises à jour de BDD SPIP 3.0 (ou 3.1 ?)

  25 mai 2021

  D’après https://core.spip.net/projects/spip/wiki/WikiStart#Anciennes-versions

  Et le fait que le premier numéro de https://git.spip.net/spip/spip/src/branch/master/ecrire/maj/legacy/svn10000.php est le 10990 (1.9.2d = 11132), on pourrait conserver pour la 4.0 la migration probablement depuis 1.9.2d. Sans que ça soit très gênant pour le moment.

  Mais même, le fichier maj/v019.php a la nouvelle écriture, et commence en 1931 (1.7.0 = 2414)...
  On pourrait même conserver depuis 1.7.0.

  Mais le veut-on vraiment ?
  On peut conserver « à partir de 2.0.0 » (13469), pourquoi pas ? ou toute version au dessus…
  Ou à partir de 1.9.2 ou 1.8… ou je ne sais pas…

  Bref… pour moi tant qu’on vire les maj/vxxx.php antérieurs à l’ancien formalisme, déjà ça me va.

  Mais indépendamment de ça, conserver ad-vitam les trucs, ça a pas forcément trop de sens quand même.

• video created by moviepy doesn't play on web

  18 février 2016, par R. Glenn

  I’m playing around with moviepy, with the intent of creating videos to imbed in webpages. However, I’m having trouble getting the videos that I create to actually play in chrome and firefox (it does play in safari :/ ).
  Firefox claims the "file is corrupt".

  I find it extremely likely I haven’t installed something properly. I followed (among other things, since I’m not yet authorized to post enough links so as to fully describe my situation, #thanksStackOverflow ;P) http://wiki.webmproject.org/ffmpeg/building-with-libvpx, but according to [link I would have shared if allowed :P] that stuff is all "automatically installed during MoviePy’s installation", so I’m not sure how I could have messed it up.

  see example code (I’ve tried it with ’python’, ’python3’ and ’python3.5’) :

  from moviepy.editor import *
  
  
  
  filepath = "../read_videos/MOVI0011.avi"
  
  file = VideoFileClip(filepath)
  
  
  
  clips = []
  
  clips.append(file.subclip(10, 12))
  
  clips.append(file.subclip(20, 22))
  
  clips.append(file.subclip(30, 32))
  
  clips.append(file.subclip(40, 42))
  
  
  
  concatenated_clip = concatenate_videoclips(clips)
  
  
  
  concatenated_clip.write_videofile("../write_videos/clip.mp4", fps=24, codec='mpeg4')

• ffmpeg, HLS options, ffmpeg components for dummies ? [closed]

  10 juin 2013, par Vetal

  I am trying to make some HLS encoding with ffmpeg

  After playing a lot (in Ubuntu 12.04) with ffmpeg I realized I do not understand basic questions.

  How to make a ffmpeg "by the book" ?

  I've started a "sudo apt-get install ffmpeg"

  I finished with a manual install :

  http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20quickly%20compile%20FFmpeg%20with%20libx264%20%28x264,%20H.264%29

  Latter needed a following command to get rid of build error, where I spent quite some time with :

  sudo apt-get remove ffmpeg x264 libx264-dev

  So, now I've got to the documentation for HLS : http://ffmpeg.org/ffmpeg-all.html#hls-2

  Trying to run some stuff :

  ffmpeg -i 3.mp4 hls.m3u8

  Error : Unable to find a suitable output format for 'hls.m3u8'

  ffmpeg -i 3.mp4 -hls_time 10 hls.m3u8

  Error :
  Unrecognized option 'hls_time'
  Failed to set value '10' for option 'hls_time'

  Anyway, looks like an options specified in different formats, e.g. 'vbsf' vs 'v:bsf', -vcodec and -v:c, etc. etc. Like there are few alternative versions

  After starting with it some time ago, I feel more pessimistic now like I missed some fundametals. Any Ideas for the things above ?

  Thank you
