• Java ProcessBuilder : space within quotation marks

  29 mai 2014, par Zahlii

  I am using ProcessBuilder to run FFMPEG to convert and label some of my MP3-Files.

  Manually using the following in a .bat file works as expected :

  "E:\Dokumente\workspace\MusicBot\ffmpeg\bin\ffmpeg.exe" 
  
      -i "The Glitch Mob - We Can Make The World Stop.mp4" 
  
      -metadata author="The Glitch Mob" 
  
      -metadata title="We Can Make The World Stop" 
  
      -ab 320k "mob.mp3"

  Now what i am trying to achieve using java’s ProcessBuilder

  ProcessBuilder pr = new ProcessBuilder(FFMPEG_PATH, 
  
      "-i", target.getAbsolutePath(),
  
      "-metadata", "title=\"We Can Make The World Stop\"", 
  
      "-metadata", "author=\"The Glitch Mob\"", 
  
      "-ab", "320k", 
  
      tar.getAbsolutePath());

  results in a [NULL @ 000000000032f680] Unable to find a suitable output format for 'Can'.
  Using title and author without spaces in them works, however.

• FFMPEG not save logs when converting to audio format

  27 mars 2017, par PUXIII

  The command does not save or even create a file :

  ffmpeg -i "video.mp4" -f mp3 "audio.mp3" -vstats_file "log_file.log"

  And if you convert to a video file, everything normally creates and writes :

  ffmpeg -i "video.mp4" -f mp3 "video.avi" -vstats_file "log_file.log"

  Goal : to pull out the time from the log file and bind it to the process bar.

  There are no problems with video, everything works. But with the sound does not work.

  I tried the command :

  ffmpeg -i "video.mp4" -f mp3 "video.avi" >2 "log_file.txt"
  But there are other problems popping out. Since I run it all from the python using the subprocess

  ffmpegProc = subprocess.Popen(ffmpegCommand, startupinfo=startupinfo, shell=True)
  , I can not kill the running process, because it is started with the attribute shell=True, and only the shell is killed.and only the shell is killed.
