ActiveX Control - Toolbar is not visible
This problem occurs on every 3.x version of VLC. Older versions are fine. I tested this on M3U8 web links (.ts files inside) but I think it doesn't matter what is playing. AX control bar (toolbar with buttons and seeker) is only visible before video is played. As soon as video is playing, toolbar becomes not longer available/visible. You can't revive it with mouse (as usual) or in any other way. In fullscreen situation looks the same.
ActiveX is used in Delphi project (newest Delphi 10.1). I don't know how this problem affects AX control inside webbrowser (if at all).
