• Bash script that lists files in a directory doesn't work

  28 juillet 2018, par Fabrizio Gabriele

  I made a bash script because I need to convert a lot of files in a directory from .MOV to .mp4 format.
  I created this script for the purpose :

  #!/bin/bash
  
  
  
  touch .lista
  
  ls -1 "$1" | grep -i .MOV > .lista
  
  list= `pwd`/.lista
  
  cd "$1"
  
  while read -r line;
  
      do filename=${line%????}
  
      ffmpeg -i "$line" -vcodec copy -acodec copy "$filename.mp4"; done < $list
  
  rm .lista

  This script is supposed to convert me each .MOV file into the directory indicated by $1, but it doesn’t work, it converts me only one file, then it terminates. I can’t understand why. What’s wrong with that ?

• checkasm : Test whether the native FFmpeg timers work

  checkasm : Test whether the native FFmpeg timers work
  On some platforms (in particular, ARM/AArch64), the implementation
  
  of AV_READ_TIME() may use a privileged instruction - in such
  
  cases, benchmarking just fails with a SIGILL.
  Instead of crashing, try executing AV_READ_TIME() once within
  
  a region with the signal handler active, to allow gracefully
  
  informing the user about the issue.
  This matches the dav1d checkasm commit
  
  95a192549a448b70d9542e840c4e34b60d09b093.
