>I cannot confirm, that a local declarations of the MediaPipeline or any
other MediaControl makes a difference (V3.18.4). I tested it with the
given example and the result was exactly the same. I am assuming that a
Quit command is equal to a click on the stop button of the IDE which
also preserves the contents of the mp3 file. I informed Benoît about
that in an email which I sent mistakenly to his personal account - my
apologies.
I just tried to run the given example as a non-GUI-application and can
confirm that the mp3 file is not emptied when doing this:
...
pl.play
Wait 20
pl.Stop
pl.close
This also worked with the GUI-application, but when I closed the FMain
(without any further command) the mp3 file was empty again. Does FMain
act as a media container which fills the mp3 file and kills its content
when being closed?
When the non-GUI application is brutally terminated by clicking on the
stop button of the IDE or by imposing a Quit command the contents of the
mp3 file is also preserved. But the same happens with the GUI version.
