Media Plays in Aeperate Window Instead of Within Application

[1ubuntuuser]

System: Debian 11 KDE 64-bit (X Display)
VLC: 3.0.18
When playing a video using the example app the video plays in a new window. The new window is sized to the media and has the VLC logo in the header and launcher.

Setting the EmbedWithin to Window instead of RectControl made no change.

m.Player.Embededwithin matches the Handle of VLCMediaPlayer

Using the GTK inspector on a simple app with the player apparently embedded doesn't show that Canvas has any children, should it have?

The libVLC discord group has been helpful. Here are some logs:

I added XInitThreads() call. Now I get the following:

I'm sorry for not responding to this sooner. I didn't see the notification.

Pass "--no-xlib" to libvlc_new() to fix this.

This solution is problematic. I've never been able to successfully pass any arguments into libvlc_new(). I can't seem to figure out how to pass a C-style vector of strings like it expects.
