• Convert image sequence to video using ffmpeg and list of files

  13 mai 2015, par rensa

  I have a camera taking time-lapse shots every 2–3 seconds, and I keep a rolling record of a few days’ worth. Because that’s a lot of files, I keep them in subdirectories by day and hour :

  images/
  
      2015-05-02/
  
          00/
  
              2015-05-02-0000-02
  
              2015-05-02-0000-05
  
              2015-05-02-0000-07
  
          01/
  
              (etc.)
  
      2015-05-03/

  I’m writing a script to automatically upload a timelapse of the sunrise to YouTube each day. I can get the sunrise time from the web in advance, then go back after the sunrise and get a list of the files that were taken in that period using find :

  touch -d "$SUNRISE_START" sunrise-start.txt
  
  touch -d "$SUNRISE_END" sunrise-end.txt
  
  find images/"$TODAY" -type f -anewer sunrise-start.txt ! -anewer sunrise-end.txt

  Now I want to convert those files to a video with ffmpeg. Ideally I’d like to do this without making a copy of all the files (because we’re talking 3.5 GB per hour of images), and I’d prefer not to rename them to something like image000n.jpg because other users may want to access the images. Copying the images is my fallback.

  But I’m getting stuck sending the results of find to ffmpeg. I understand that ffmpeg can expand wildcards internally, but I’m not sure that this is going to work where the files aren’t all in one directory. I also see a few people using find’s --exec option with ffmpeg to do batch conversions, but I’m not sure if this is going to work with image sequence input (as opposed to, say, converting 1000 images into 1000 single-frame videos).

  Any ideas on how I can connect the two—or, failing that, a better way to get files in a date range across several subdirectories into ffmpeg as an image sequence ?

• Anomalie #3444 (Nouveau) : Nombreuses erreurs dans les log avec une instal en SQLite 2

  10 mai 2015, par Franck Dalot

  Bonjour
  SPIP 3.1.0-beta [22129]
  PHP 5.3.29 chez ovh
  Aucun préfix de table "particulier"
  Installation en SQLite 2
  J’ai un fichier mes_options qui ne contient que :
  <?php
define('SPIP_ERREUR_REPORT',E_ALL);

  Je viens de faire un test d’installation tout neuf en SQLite 2.
  Une fois l’installation fini, je regarde de suite les logs dans tmp/log
  Je constate de nombreuses erreurs y compris "critique" dans les fichiers "maj.log", "spip.log", "spip.log.1", "sqlite.log" et "sqlite.log.1"
  Le site semble fonctionnel, mais pourtant, si j’essaie d’ouvrir le fichier avec https://github.com/lazierthanthou/sqlite-manager cela me sort comme quoi la bdd aurait un problème, donc impossible de la voir avec.

  Donc, dans le doute, ou il y a un vrai problème, je préfère faire un ticket en attendant que d’autres confirme ou regarde s’ils ont des choses qui sembleraient anormal.

  Mon test
  1) spip 3.1 svn 22109
  2) pas de plugins/auto mais le flux déclaré
  3) plugin tickets mis manuellement dans plugins
  4) j’active le plugin. Il se "préactive" en entendance les dépendances
  5) lorsque j’installe saisies, le plugin tickets peut bien s’activer
  6) mais les tables n’ont pas été installées
