• FFMPEG - Instructional video combining letters to a background to form a word

  6 juin 2020, par Knide

  I'm trying to help with coding a FREE site for instructional video for kids on how to write in australian. To help with the current pandemic that we are experiencing right now.

  



  Anyway, I'm new to ffmpeg and would like to do the letter combinations programatically using it.

  



  So basically I have a form where teachers or parents can enter a word, and I have video instructions for each letter, and would combine them to form the word.

  



  Example : Dog

  



  This is the background :
https://drive.google.com/file/d/1Ds1sRKQ98c5d31dI6qkqTrp1U9f89nv2/view?usp=sharing

  



  These are the letters :

  



  D - https://drive.google.com/file/d/1DHa1sZ7mklY1p3lquD8h5kTbXaZmtB_z/view?usp=sharing

  



  o - https://drive.google.com/file/d/1Ytwq_3l7x0vRDMEpZpmFjT9QNICYWH_D/view?usp=sharing

  



  g - https://drive.google.com/file/d/16jcOsrSbMSbsk2vsqeMXv9Cc4Uss7qtj/view?usp=sharing

  



  And the output would become :
https://drive.google.com/file/d/1RT38IOwXsL9kW9mj41KrxwfI_kdZy45j/view?usp=sharing

  



  If you could help with supplying what ffmpeg code we could use to have the output video, that would be great.

• When I run `ffmpeg` in the background, how do I prevent `suspended (tty output)` ?

  4 novembre 2017, par Jim DeLaHunt

  I have a sh script which calls ffmpeg on several files. When I try to run this script in the background, redirecting output to a file, the job starts but then immediately suspends :

  % bin/mp3convert.sh path/a/b &> ~/tmp/log.txt &
  
  [1] 93352
  
  % 
  
  [1]  + suspended (tty output)  bin/mp3convert.sh path/a/b &> 

  If I try making the script continue in the background, it immediately suspends again :

  % jobs
  
  [1]  + suspended (tty output)  bin/mp3convert.sh path/a/b &> 
  
  % bg %1
  
  [1]  + continued  bin/mp3convert.sh path/a/b &> 
  
  % jobs
  
  [1]  + suspended (tty output)  bin/mp3convert.sh path/a/b &> 
  
  %

  I can make the script continue, by making it the foreground, but then my terminal is occupied until the script finishes. That means I don’t get the benefit of running the script in the background.

  % 
  
  [1]  + suspended (tty output)  bin/mp3convert.sh path/a/b &> 
  
  % fg %1
  
  [1]  + continued  bin/mp3convert.sh path/a/b &> 
  
  % # much time passes with no activity on terminal, then script finishes
  
  %

  How can I make the script run cleanly in the background ?

  A simplified version of my script is :

  #!/bin/sh
  
  # mp3convert.sh
  
  for f in "$1"/*.flac; do
  
      ffmpeg -i "$f" -c:v copy path/to/dest/"$(basename -s .flac "$f")".mp3
  
  done

  I am running on Mac OS X 10.11.6, with ffmpeg version 3.4 supplied by MacPorts.

  An apparently related question is why do I get “Suspended (tty output)” in one terminal but not in others ?. The answer there is to set the terminal state with stty -tostop. That didn’t help me ; I already had that state set.
