Exception during shutdown

Post by oliver » Wed Aug 08, 2018 2:11 am

Ever since I added TRVCamcorder and TRVCamera to my application I was getting a strange "BluetoothSocketException" during program shutdown:

Capture.PNG (7.38 KiB) Viewed 603 times
BTW: My application doesn't even do anything with Bluetooth.

I narrowed it down to setting the TRVCamcorder->Activate=true. When I don't perform that one step, my application shuts down without any issues.

I tried to duplicate this in a small sample application, but unfortunately I was not able to duplicate it.

Any ideas what could be causing this? Anything I should do to TRVCamcorder or TRVCamera before closing the app (aside from the obvious TRVCamcorder->Activate=false and TRVCamera->Abort())?

While we have some fixes in initialization/finalization code since the release of RVMedia 5.3 (I hope we will be able to release it after several days), I am not sure that this problem is fixed.

Do you use C++Builder?
I found this information about this exception: https://stackoverflow.com/questions/349 ... to-mongodb

I implemented the workaround specified in that link, but I still get the same error during shutdown.

I added a TFDConnect->Connected=true in a test application, but no exception was raised during shutdown.

I even tried to trigger that exception by calling WSACleanup() in my application directly (without calling WSAStartup() first), but again no exception.

Looks like that 2 year old issue may have been fixed. Setting TRVCamcorder->Activate=true just causes that same exception.

Yes, I am using C++ Builder 10.2.3.

Will your updated version be available for users of your demo version?

We need some time to investigate this issue. It looks like this is a C++Builder issue and it is not directly related to our code, so it cannot be fixed in our code. But I'll try to find a workaround.
