Hi, @CodePunk-

Sorry for the late response. I managed to re-create the issue on Windows.
Basically the first time you run youtube-dlg after the installation it seems that it cannot locate ffmpeg & ffprobe for some reason. Also, from a quick view your log errors seem completely unrelated to the mp3 issue.

I'm pretty busy right now but i'm going to take a closer look on the issue in the next days.

@CodePunk-

Bug reproduce steps (build b791ac8) :

1. Run youtube-dl-gui.exe
2. Change directory using the "..." button
3. Select mp3 as output format
4. Try to download a new URL
5. You should get an Error status (could not locate ffmpeg)

This behaviour was occurring due to the DD_CHANGE_DIR property of the wx.DirDialog widget.
You can download the new build from here 8e60ff3. Please let me know if it works for you.

For more informations regarding this bug you can check:

• Commit 8e60ff3
• wx.DirDialog docs https://wxpython.org/Phoenix/docs/html/wx.DirDialog.html
