• ffmpeg : Invalid data found when processing input

  20 septembre 2018, par Rich_F

  I have a situation where ffmpeg is throwing an error :

  Invalid data found when processing input

  I’ve reviewed other answers here, but my situation is different. I generate in Ruby, a text file with a list of input files I want to concatenate together into one large video.

  I generate in Ruby, the command meant for bash, which is also output for me to manually copy :

  ffmpeg -y -f concat -safe 0 -i /Volumes/Dragon2/Yums/randoms.txt /Volumes/Dragon2/Yums/final.mp4

  Throws an error :

  /Volumes/Dragon2/Yums/randoms.txt: Invalid data found when processing input

  Here is that file :

  file '/Volumes/Dragon2/Yums/0CEDC3CA-4571-4271-9938-A161EC2A887B.mov'
  
  file '/Volumes/Dragon2/Yums/0D25D907-D053-443B-AFC6-9F12B1711BBF.mov'
  
  file '/Volumes/Dragon2/Yums/6A272808-7706-435D-801E-ACE6B42EC749.mov'
  
  file '/Volumes/Dragon2/Yums/6E9BA2F1-C5E7-4C1C-B290-D116105732FA.mov'
  
  file '/Volumes/Dragon2/Yums/0A41C7B7-74CE-484E-B029-3AE57B8BB4EA.mov'

  When bash runs it, it complains about the input file randoms.txt having invalid data. When I copy and paste the very same command in bash, it works fine. I’m stumped as to how the two are different and why ffmpeg is not happy when initiated in the shell.

  How can I get this to work ? What am I missing ? Cheers

  EDIT : Original ruby code :

  `clear`
  
  require 'pathname'
  
  require 'pp'
  
  
  
  s = '/Volumes/Dragon2/Yums'
  
  files = []
  
  
  
  Dir.foreach(s) do |path|
  
    files << "#{ s }/#{ path }"  
  
  end
  
  
  
  result = files.sample(files.size)           # randomizer
  
  
  
  f = File.open("#{ s }/randoms.txt", 'w+')
  
  result.each_with_index do |item, i|
  
    pp "#{ i }: #{ item }" if item.include?('mov')
  
    f << "file '#{ item }'\n" if item.include?('mov')
  
  end
  
  
  
  `echo `
  
  
  
  File.delete("#{ s }/final.mp4") if File.exists?("#{ s }/final.mp4")
  
  s = "ffmpeg -y -f concat -safe 0 -i #{ s }/randoms.txt #{ s }/final.mp4"
  
  puts s
  
  
  
  sleep 3
  
  `#{ s }`

  I have also tried system s as well with the same error. The syntax is generated fine, output fine, operates fine manually.
