  avutil/channel_layout : print known layout names in custom layout
  If a custom layout is equivalent to a native one, check if it matches one of the
  
  known layout names and print that instead.

• dyld[16458] : Library not loaded : @rpath/libavcodec.framework/libavcodec while running my flutter app on iOS

  31 janvier 2023, par Stéphane de Luca

  Compilation is successful. But When I run the code, I get this.

  


  Here is the full trace.

  


  Any idea ?

• apply ffmpeg to many files

  30 juillet 2015, par puchu

  I have written simple script :

  #!/bin/bash
  
  find . -name "*.m4a" | while read filename;
  
  do
  
      new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
  
      if [ ! -f "$new_filename" ]
  
      then
  
              #ffmpeg -i "$filename" -acodec flac "$new_filename" > /dev/null 2>&1;
  
              #wait $!;
  
              echo "$filename";
  
              echo "$new_filename";
  
      fi
  
  done

  it outputs correct result :

  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
  
  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
  
  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
  
  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flac

  if uncomment ffmpeg and wait :

  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
  
  ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
  
  uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
  
  uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flac

  And no flacs has been done !

  PS

  #!/bin/bash
  
  find . -name "*.m4a" | while read filename;
  
  do
  
      new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
  
      if [ ! -f "$new_filename" ]
  
      then
  
              ffmpeg -i "$filename" -acodec flac "$new_filename";
  
              echo "$filename";
  
              echo "$new_filename";
  
      fi
  
      sleep 5;
  
  done

  1) encode start but suddenly stop with no error messages

  2) encode couldn’t start because of "uilibrium" instead of "./Equilibrium"

  3) = 1)

  4) = 2)

  ...

  last) correctly
