ZeDMD starts screensaver after returning from VPX to Frontend #481

Open pjeantaud opened 4 months ago

pjeantaud commented 4 months ago

Hi Markus,

Thanks for this version 2.2.3.

Here’s my feedback, you can see it on the following video : http://pjeantaud.free.fr/Freezy/Freezy_2-3-3.mov

1) run PinballX, ZeDMD displays the DMD presentation video: OK. 2) lauch a VPX table, ZeDMD initialize, then display the DMD game: OK. 3) exit the game. Under PinballX, ZeDMD does not display anymore the presentation video: KO. 4) run another table, ZeDMD displays the DMD game as in step 2: OK.

So PinballX displays the presentation video on DMD only once. Thank you for you commitment.

The title should be "ZeDMD starts screensaver after returning from VPX to Frontend".

The same has been reported for Pinball Y via discord.

@freezy so it looks like VPX doesn't cause a call to Dispose() if it is closed by the frontend. Or the Frontend doesn't call Init() again to get the connection to the DMD.

I don't think that this is a ZeDMD issue. The only difference between ZeDMD and others might be that a process could not open the connection if another process still "owns" the serial port.

@zesinger just told me that people reported in forums that in dmddevice.log:

System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it

@freezy how is dmdext supposed to work with frontends and VPX both accessing DMD devices?

Hello,

FYI, I made some extensive testing on my configuration:

The correct behavior is obtained with Freezy 2.2.1

Versions 2.2.2 and 2.2.3 present the problem described ahead. Thanks all for your commitment.
