• Bash - Get time difference from ffmpeg

  2 octobre 2017, par arjuncc

  I am building an an application using ffmpeg. In which I need to subtract start time of two files(there are only two files as input). following is my code.

  #!/bin/bash
  
  mkvarray=()
  
  mkvarray_name=()
  
  for video_name in *.mkv; do
  
  output=$(ffprobe -v error -show_entries format=start_time -of default=noprint_wrappers=1:nokey=1 "$video_name")
  
  mkvarray+=($output)
  
  mkvarray_name+=("$video_name")
  
  done 
  
  
  
  arraylength=${#mkvarray[@]}
  
  for (( i=0; i<${arraylength}; i++ ));
  
  do
  
    echo ${mkvarray_name[$i-1]} "------>  " ${mkvarray[$i-1]}
  
  done
  
  
  
  max_number=0
  
  if [[ ${mkvarray[0]} < ${mkvarray[1]} ]]; then
  
    echo "first-------------"
  
  
  
    max_number = ${mkvarray[0]} - ${mkvarray[1]}
  
    echo "first " $max_number
  
  else
  
     echo "second-------------"
  
     max_number = ${mkvarray[0]} - ${mkvarray[1]}
  
     echo "second " $max_number
  
  fi
  
  
  
  echo $max_number

  OUTPUT

  $ ./ffmpeg_updated.bash RTda01986c816052106c00f417387a83ff.mkv ------>
  2.040000 cc.mkv ------> 2.040000 RT4bafb05e1b36885c75d7d67a16f5e3b2.mkv ------> 4.086000
  first------------- ./ffmpeg_updated.bash : line 24 : max_number : command
  not found first 0 0

  from this I understood that, floating point arithmetic is not possible. So Is there any suggestion to proceed from this. I am pretty much new to bash. Or is there any alternative way to get things done in ffmpeg ?

• fate : add test for asetnsamples filter with padding disabled

  fate : add test for asetnsamples filter with padding disabled
  Adds another test for asetnsamples filter where padding of the last
  
  frame is switched off. Renames the existing test to make the difference
  
  obvious.
