Delphi libVLC hiding RTSP on change dock type in TdxDockPanel at runtime
Posted: 28 Apr 2021 12:40
Hi guys.
It is my first question on this forum so sorry if I do it something not right.
I have made an application where are two forms. The first one is the Main form, the second is normal TForm with TPanel, and this panel displays the RTSP stream from the web camera by the VideoLanClient library. This works fine but … Instead of normal TPanel on the main form I have added TdxDockSite and TdxDockPanel from DevExpress package. It works fine until the user changes the docking type in runtime. Then the RTSP stream has disappeared. I don't know what is going on because when I have run TForm.Hide and TForm.Show programmable then this RTSP stream works fine. Even if I have resize TdxDockPanel in runtime it works. The problem is only on manual changing docking in runtime. In compiler I have seen such info when I have move mouse over panel:
