• How to run one script after another in Apple Script

  19 juillet 2015, par mskx4

  I’m trying with Apple Script to run three different scripts that would alow me to :

  1. Convert a purchased m4a file into an "anonymized" m4a file and extract its artwork (with ffmpeg)
  2. Attach the artwork to the file previously converted, since the converted file won’t maintain its artwork (with AtomicParsley)
  3. Remove the artwork from his path

  I don’t have any kind of programming knowledge, I’ve collected different script from the web and tried to make an app that could do these 3 simple task :

  on open argv
  
     set paths to ""
  
     repeat with f in argv
  
         set paths to paths & quoted form of POSIX path of f & " "
  
     end repeat
  
     tell application "Terminal"
  
          do script "for f in " & paths & "; do ffmpeg -i \"$f\" -acodec copy -y \"$f\" output.jpg; done"
  
          activate
  
          do script "for f in " & paths & "; do AtomicParsley \"$f\" --artwork output.jpg; done"
  
          activate
  
          do script "rm output. jpg"
  
          activate
  
     end tell
  
   end open

  The problem is that, when I drop a file on the app, it opens three terminal windows at once and it runs the three tasks in the same time, with the obvious result that the conversion fails : the first task overwrites the input file, and the second script should use the output of the first one as its input file. So I need the three scripts to be executed successively, one after another.

• How to create a video from images with timestamps, sizes and positions with ffmpeg

  23 octobre 2022, par Maxou

  I want to convert a subtitle file (.sup) to a video file with transparency. To do that I convert my .sup file into a multitude of png files listed in a xml file.

  


  XML File

  


  &lt;?xml version="1.0" encoding="UTF-8"?>&#xA;<bdn version="0.93">&#xA;  <description>&#xA;    <format videoformat="1080p" framerate="25" dropframe="False"></format>&#xA;    <events type="Graphic" firsteventintc="00:00:00:01" lasteventouttc="00:23:59:05" numberofevents="708"></events>&#xA;  </description>&#xA;  <events>&#xA;    <event intc="00:00:00:01" outtc="00:00:03:09" forced="False">&#xA;      <graphic width="1146" height="65" x="387" y="985">seq_0001.png</graphic>&#xA;    </event>&#xA;    <event intc="00:00:04:19" outtc="00:00:07:14" forced="False">&#xA;      <graphic width="1112" height="65" x="404" y="985">seq_0002.png</graphic>&#xA;    </event>&#xA;    <event intc="00:00:08:06" outtc="00:00:10:23" forced="False">&#xA;      <graphic width="681" height="65" x="619" y="985">seq_0003.png</graphic>&#xA;    </event>&#xA;  </events>&#xA;</bdn>&#xA;

  


  I tried to generate a video using this command

  


  ffmpeg -t 20 -s 1920x1080 \
-f rawvideo -pix_fmt yuva420p -i /dev/zero \
-i seq-1.png \
-filter_complex "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \
empty.webm


  


  It works but it takes a long time and I only manage to do it with one image.

  


  It is possible to generate a video with all the images (with size, position and timestamp) include in the xml file ?
