• Anomalie #4623 : Styles des fieldset dans l’espace privé

  18 avril 2021

  Je découvre les fieldset.editer qui sont des lignes pour les .choix, introduit assez récemment. Donc ça fait une option de plus à gérer.

  Dans quelle mesure Tcharles il y a besoin du .editer-groupe dans le fieldset.editer-surgroupe ? Est-ce que ça pourrait servir pour passer les champs .editer dedans en colonne (flexbox horizontal ?) sur certains fieldset ? (Je suppose qu’on en aurait pas besoin pour ça). Et donc que ça simplifierait si on met directement fieldset.editer-groupe

  <span class="CodeRay"><span class="tag">form</span>
    <span class="tag">div</span><span class="class">.editer-groupe</span>
      <span class="tag">div</span><span class="class">.editer</span>
      <span class="tag">div</span><span class="class">.editer</span>
      ...
   
    <span class="tag">fieldset</span><span class="class">.editer-groupe</span>
      <span class="tag">legend</span>
      <span class="tag">div</span><span class="class">.editer</span>
      <span class="tag">div</span><span class="class">.editer</span>
   
    <span class="tag">div</span><span class="class">.editer-groupe</span>
      <span class="tag">div</span><span class="class">.editer</span>
      <span class="tag">fieldset</span><span class="class">.editer</span>
        <span class="class">.choix</span> 
      <span class="tag">fieldset</span><span class="class">.editer-groupe</span>
         <span class="tag">legend</span>
         <span class="tag">div</span><span class="class">.editer</span>
         <span class="tag">div</span><span class="class">.editer</span>
         <span class="tag">fieldset</span><span class="class">.editer-groupe</span>
            <span class="tag">legend</span>
            <span class="tag">div</span><span class="class">.editer</span>
            ...
   
    <span class="tag">fieldset</span><span class="class">.editer-groupe</span>
      <span class="tag">legend</span>
      <span class="tag">div</span><span class="class">.editer</span>
      <span class="tag">fieldset</span><span class="class">.editer-groupe</span>
         <span class="tag">legend</span>
         <span class="tag">div</span><span class="class">.editer</span>
         ...

  Il me semble que dans ce cas on peut toujours différencier
  - un form fieldset.editer-goupe (racine) (du moins avec style minimums = div.editer-groupe)
  - d’un form .editer-groupe fieldset.editer-groupe (mélangé avec d’autres champs = style plus élaborés avec indentation)

  En fait ça me parait assez cohérent de dire "Un fieldset c’est un groupe d’édition" (.editer-groupe) la seule grosse différence est la présence du legend. (et éventuellement de la démarcation / indentation)

• how to create multiple period using ffmpeg, from two input videos to multi period on the DASH mpd

  14 mai 2020, par Sunny

how do I make a command line for making a DASH mpd to have multiple periods. 
who does know the way to make the thing ?

• check media resolution, if resolution is big ffmpeg it, if output is smaller than original delete the original else delete the output

  13 avril 2015, par The Wolf

  I have my storage VPS filled with videos, and hoping I can free up some space, their resolution is pretty big so I decided to re encode them with ffmpeg to a smaller resolution, I am doing every thing manually, first I check using mediainfo test5.mkv the resolution

  ...
  
  Width                                    : 1 280 pixels
  
  ...

  if the width is greater than 720 pixels I issue the following command :

  ffmpeg -i 'test5.mkv' -vf scale=720:-2 -acodec copy -vcodec libx264 -scodec copy -threads 12 -crf 28 -x264-params keyint=240:min-keyint=20 -preset:v slow '[Encoded] test5.mkv'

  then after that I delete the original video if the output has smaller size than the original

  I am hoping there is a script that can automate this, like I will run on a directory then, it will look for all .mkv to subdirectories recursively to perform this checks and actions. How to do this ?

  Also, I am worried that it could fail if I reach automation, since there are special characters in the video’s name of some like single quotes, double quotes, or `, so I will it can be escaped properly.

  Thanks !

  After some google I ended up with the following snippet, I am worried if this is enough, but I’m afraid to run it since I am not sure if it would damage my unix

  #!/bin/sh
  
  
  
  for file in *.{mkv}; do
  
  target="[720p]-${file%.*}.mkv"
  
  [[ -f "$target" ]] && { echo "skipping $file - $target exists" ; continue; }
  
  
  
  
  
  eval $(ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width "$file")
  
  size=${streams_stream_0_width}x${streams_stream_0_height}
  
  if [ "$streams_stream_0_width" -ge 720 ]; then
  
  echo ffmpeg -i "$file" -vf scale=720:-2 -acodec copy -vcodec libx264 -scodec copy -threads 12 -crf 28 -x264-params keyint=240:min-keyint=20 -preset:v slow "$target"
  
  
  
  fi
  
  done

  can somebody please tell me if my snippet should work ?

  UPDATE

  as it turns out if [ "$streams_stream_0_width" -ge 720 ]; then fails because the width is not integer ? line 10: [: : integer expression expected I am not sure why it is not integer, how can I make it integer ?
