cec-tray crashes with System.ObjectDisposedException with Kodi

[lukjak]

Hello,

cec-tray (6.0.2) crashes with exception when Kodi (https://kodi.tv) application starts. Please mind that I use my own Kodi build with all CEC support disabled and which does not load cec.dll - so there is no conflict here.

System.ObjectDisposedException
   w System.Windows.Forms.Control.CreateHandle()
   w System.Windows.Forms.Form.CreateHandle()
   w LibCECTray.ui.CECTray.SetVisibleCore(Boolean)
   w System.Windows.Forms.Control.Hide()

   w System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
   w System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
   w System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
   w System.Threading.ThreadHelper.ThreadStart()

Background for this problem:

My current TV/Amp/PC setup is not working quite correctly with the current Kodi (20.1 libcec 4.0.4 or 4.0.7) - xbmc/xbmc#23260. I wanted to try to use cec-tray for controlling Kodi instead of built-in support, as it seems to always work correctly, but I observed that cec-tray is closed immediately upon Kodi startup. I thought it is some CEC clients collision. So I build a Kodi version totally without CEC support (it does not require cec.dll to run at all) and observed the same issue with cec-tray. Then I discovered the problem in Windows Event Log.

Any progress with this? I'm also getting a cec-tray crash when running kodi 21.2 on Windows 10.

Well.. While kodi is looking for phericals (aggressively?!), it does not matter as there is a event that is triggered if kodi is running:

cec-dotnet/src/LibCecTray/controller/applications/internal/KodiController.cs

Line 72 in 3885820

static void RunningChanged(bool running)

Disabling above line and leaving cec disabled in kodi, actually works fine. Of cause without fancy stuff like pause when switching hdmi input. Note that cec tray must be lunched before kodi according to my testing so far.

By design, or limitations, the connection to the CEC adapter seems to be limited to one client.
