Same question as mine :
https://forum.videolan.org/viewtopic.php?f=15&t=119359
However there is a way to put objects over the video frame:
You need two Windows with the same size and same position - lets call them "VideoWindow" and "ControlWindow" and align them with anchors
still there are two problems:
1. the "ControlWindow" cant be resized - means that you only have a specified width => well in your case (like the screenshot) it isnt a problem.
2. If you click into the "VideoWindow", the "ControlWindow" will disappear because the "VideoWindow" is now the top layer

note: if you open the .vlt file via vlc skin editor do not save it - it will crash
good luck
