• ffmpeg : Generate video from picture

  16 octobre 2013, par Tchoupi

  I'm currently trying to generate a video from a single picture (1980*1024)
  Here my cmd :

  ffmpeg -threads 8 -r 1 -loop 1 -i "C:\Library\Titling\__Resources\1.jpg" -t 5.00 -pix_fmt yuv420p -vcodec libx264 -b:v 1500k -s 720:576 -aspect 1.0000 -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4"

  At this step I have two problems :
  first is a warning during execution
  deprecated pixel format used, make sure you did set range correctly
  The second is the video do not work correctly in VLC (video is "black") but it work in wmp...
  

  Then I add an empty audio track :

  ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

  After that I concat this video to others using complex filter .
  When I concat my videos I have this message :
  

  [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

  And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
  perhaps it is not related
  I don't know ...

  Here my concat command and execution log
  

  D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115

• Anomalie #3227 : Bug date de publication

  17 juin 2014, par Eric Camus

  Petit addendum sur la chose des dates de publication et antérieure. Outre le fait reconnu que la saisie manuelle permet de faire tout et surtout n’importe quoi de la date. Si on arrive a afficher le message d’erreur, alors un clic sur "annuler" n’annule rien car la fonction "formulaire_date_verifier_dist" ne tiend pas compte de ce cas et on reste avec notre erreur, les formulaires ouverts !.

  Pour revenir sur cette date : pourquoi ne pas vérouiller le fait qu’elle doit être bien formatée : JJ/MM/AAAA ou J/M/AA (=>AA+2000), ce serait un problème de moins.

  Pour corrigé tout cela, le fichiers "date.php" dans "/prive/formulaires/", j’ai donc copié le test de traitement dans la vérification :
  

  function formulaires_dater_verifier_dist($objet, $id_objet, $retour=’’)
      $erreurs = array() ;
  +    if (_request(’changer’))
          foreach(array(’date’,’date_redac’) as $k)
              if ($v=_request($k."_jour") AND !dater_recuperer_date_saisie($v))
                  $erreurs[$k] = _T(’format_date_incorrecte’) ;
              elseif ($v=_request($k."_heure") AND !dater_recuperer_heure_saisie($v))
                  $erreurs[$k] = _T(’format_heure_incorrecte’) ;
          if (!_request(’date_jour’))
  
              $erreurs[’date’] = _T(’info_obligatoire’) ;
  
  +    
  
      return $erreurs ;
  
  
  

  
  J’ai aussi changé le code des deux fonctions suivantes :
  

  function dater_recuperer_date_saisie($post) 
      // autorise toutes les date de 1980 a 2099 plus 0000 et 0 a 99 transforme en 2000 a 2099
      if(preg_match(’#^01,4$#’, $post, $regs)) return array(0,0,0) ;
      if(!preg_match(’#^(0 ?[0-9]|[1-2][0-9]|3[0-1])[/-](0 ?[0-9]|1[0-2])[/-](19[8-9][0-9]|20[0-9]2|[0-9]2|01,4)$#’, $post, $regs))
          return ’’ ;
      if($regs[1]==0 and $regs[2]==0 and $regs[3]==0) return array(0,0,0) ;

  Effets de bords possible ? Je ne sait pas ! En tous cas avec ces modifications, impossible (!) d’entrée une date ou heure farfelue...

  Dernier point : les chaines de texte ’format_date_incorrecte’ et ’format_heure_incorrecte’ n’ont pas d’entrées dans les fichiers de langues.

• Problems accessing codecs with ggplot and gganimate

  19 décembre 2016, par noLongerRandom

  Using gganimate. Can’t figure out how to properly access functionality of ffmpeg, specifically I want to change the codec I’m using in the video file I’m outputting.

  # load packages
  
  library(ggplot)
  
  library(animation)
  
  library(gganimate)
  
  
  
  # Here's my data.frame
  
  myDf <- data.frame(
  
      year = c(1962, 1963, 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014), 
  
      bottom50 = c(0.195, 0.191, 0.187, 0.192, 0.196, 0.205, 0.207, 0.210, 0.209, 0.204, 0.203, 0.204, 0.205, 0.203, 0.202, 0.200, 0.200, 0.201, 0.199, 0.195, 0.190, 0.183, 0.179, 0.179, 0.177, 0.172, 0.169, 0.169, 0.168, 0.166, 0.158, 0.159, 0.158, 0.154, 0.151, 0.148, 0.149, 0.148, 0.146, 0.149, 0.148, 0.145, 0.142, 0.138, 0.135, 0.137, 0.137, 0.136, 0.130, 0.127, 0.123, 0.127, 0.125), top1 = c(0.126, 0.127, 0.129, 0.128, 0.126, 0.123, 0.122, 0.115, 0.110, 0.111, 0.111, 0.109, 0.106, 0.105, 0.105, 0.107, 0.108, 0.111, 0.107, 0.110, 0.112, 0.115, 0.125, 0.125, 0.122, 0.133, 0.149, 0.145, 0.145, 0.139, 0.150, 0.146, 0.147, 0.153, 0.160, 0.166, 0.169, 0.177, 0.183, 0.173, 0.171, 0.172, 0.183, 0.194, 0.201, 0.199, 0.195, 0.185, 0.198, 0.196, 0.208, 0.196, 0.202)
  
  )
  
  
  
  #Basic plot
  
  p <- ggplot(myDf, aes(x = year, y = bottom50, frame = year)) + 
  
      geom_line(color = "dodgerblue") + 
  
      geom_line(aes(y = top1), color = "darkred")

  The non-animated version gets me what I want :

  

  And I get an animation version output to video with :

  gganimate(p, interval = .1, title_frame = FALSE, "income.mp4")

  That’s fine, but I want to change some the output parameters, specifically : alter the dimensions, the frame rate, and use a different codec.

  # change some of the options
  
  ani.options(ani.height = 1080, ani.width = 1920, 
  
              interval = 0.04166667, other.opts = "-vcodec qtrle -f mov")
  
  # re-animate
  
  gganimate(p, title_frame = FALSE, "income.mov")

  That gives me the following error :

  Error in animation_saver(saver, filename) : 
  
    Don't know how to save animation of type mov

  I’m using ’.mov’ as my file extension because I’m trying to change to the Animation codec (so it’s no longer a .mp4 wrapper). I’ve got ffmpeg installed, so this is probably a syntax issue. But the documentation isn’t very clear here ; gganimate doesn’t have any documentation on changing codecs (or outputting any video besides an mp4), and the animation package is light on specifics as well.
