      Environment:

      MacOS 15.6.1

      Qt Creator 18.0.0 

      Qt 6.10 RC

       

      Steps to reproduce:

      1. Run audio recorder example and record a sample with MPEG-4 cotnainer and FLAC codec.
      2. Run QML media player app and play recorded file.  
      3. Using audio recorder app overwrite previously recorded file with the same settings.
      4. Play the overwritten audio file. 

      Expected: The file is played without any errors. 

      Actual: The error pops up - the file cannot be played:

      NOTE: The problem seems to be with the media player app which may cache the file. When I do the same, but skip step 2 (play the originally recorded file) then the overwritten file is played without any problems. Anyway, I report this one as it may reveals some problems.
