Thanks, but what is the $_ here, is it an object for the mp3?

Yes, the $_ is the iterator variable of the powershell for-each. Which is expressed here by the % command.

It does not work, something is blocking, but no errors. If I do the conversion from the gui vlc, it just works. I am using version 3.0.11

Vielleicht hast du noch ne Idee?

If not, I can use ffmpeg.

@tik9 there is no output, it "just takes a while", so it looks blocked. Does calling the command line without the script, work for you?

In Lin12: $newFile = $.FullName.Replace("'", "'").Replace($.Extension, ".$codec")
Where is the $_ from? I get null.

@tik9 that's strange, looks like I uploaded a bad version. It should be $inputObject of course on both places. Thank you for the hint!

Hi, I should be able to see vlc in the taskmanager, shouldn't I?
