• Troll spirit

  15 juin 2013, par Mans — Law and liberty

  Last week’s announcements from the White House of steps being taken to begin fighting back against patent trolls, along with legislation passed in Vermont for the same purpose, are worthy of praise. Whether they prove effective or not, they are a sign of the problem finally having been recognised by … Continue reading →

• Evolution #4380 : gif animé searching.gif

  9 mars 2021, par cedric -

  Bon donc on a 2 bonnes solutions :
  - le loader purement CSS : je suis parti de celui de Lea Verou https://lea.verou.me/2013/11/cleanest-css-spinner-ever/ dont j’ai retrouvé le code ici https://catswhocode.com/css-spinner/ adapté pour avoir 12 branches, arrondies, ce qui donne ça
  

  Loading…
  

  - le loader purement svg qui repose sur https://caniuse.com/svg-smil : je suis parti de https://samherbert.net/svg-loaders/ que j’ai adapté pour retrouver le spinner à 12 branches et ça donne ça pour le spinning.svg

  Qu’on peut insérer via un
  

      [(#CHEMINloaders/svg-loaders/spinning.svg|balise_svg’Loading...’,’loader’)]
  

  
  ou
  

      [(#CHEMINloaders/svg-loaders/spinning.svg|balise_img’Loading...’,’loader’)]
  

  Visuellement le rendu est assez proche entre l’un et l’autre, rien de foufou.

  Avantage/inconvénients du loader css :
  - purement css, juste 3 divs a inserer là ou on en a besoin avec la bonne chaine de langue. Il peut être stylé avec la couleur de l’espace privé (mais pas contextuellement), et dimensionné en em là où on l’utilise. Inconvénients : il faut les css et donc pour le réutiliser dans le public il faut rechoper les styles, donc les proposer aussi dans une css static (notamment si on veut styler dans l’espace prive en fonction de la couleur de preference), donc réutilisation plus laborieuse et migration plus compliquée depuis le searching.gif

  Avantage/inconvénients du loader svg :
  - c’est juste une image, qui s’utilise d’un coup de cuillère à pot n’importe où, et se style en couleur et taille avec un font-size et un color (si on l’insère avec balise_svg, sinon seulement en taille, la couleur étant du coup noire par défaut). La migration depuis le searching.gif est triviale, il suffit de changer le nom du fichier (on peut même par défaut le mettre dans une taille identique).
  Par contre le support est un peu moins bon que le loader css

  J’ai donc une petite préférence pour la version svg, mais les 2 sont gérables

• FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash

  14 février 2021, par jax

  I am struggling with FFmpeg within Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :

  


  FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile

FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfile


  


  The above command produce an error as :

  


  error executing command for rendering preset HTML5 MP4, command #1 :

  


  nice -n 19 /usr/bin/ffmpeg/ffmpeg -y -i '80137db8c3_1334836277_int_tr_19.mp4' -s 176x100 -b:v 500k -threads 0 -vcodec libx264 -preset slow -acodec aac -ab 128k '/converted/80137db8c3_1334836277_int_tr_19.mp4' 2>&1

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.


  


  Another command that I used is :

  


  FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

  The above command produces the file correctly however it cannot be played in flash player. One thing that I noticed is this may happen if the input file is mp4 as well. This command is executed for users uploading files, so the input file could be any format.
