  • ffprobe Fastest way to read video packets

  I want to extract video duration metadata from every video file in a specified directory and then sum all and view the total time in desktop app.

  I need to extract data from as much as hundreds of videos overall. In Windows I can view the total duration for many files manually when selecting them in the explorer and going into details. For 1500 mp4 files it takes about 20 seconds to make the calculations and view the total time. It’s much faster then what I’m currently getting when iterating with FFprobe.

  for filename in dirFiles:
  
     print(subprocess.check_output(['ffprobe', '-i', filename, '-show_entries','format=duration', '-sexagesimal' ,'-v', 'quiet', '-of', 'csv=%s' % ("p=0")]))

  What is the faster way to do this ?
