Royal TS 5 crash - msmpeg2vdec.dll_unloaded

Royal TS 5.0.11022


Occasionally (once every few days) RoyalTS will just suddenly close, no prompts or notifications.


Event viewer shows the following error:

It happens to me as well. It works fine and idles using about 400MB or system ram, then drops the usage to below 40MB and crashes with no error. The old TS v4 works fine, so what ever you changed in the new app increased the memory usage from 100mb to over 400mb and has added random crashing on Windows 10.


Can you please look into this issue, it is not at all good enough to advise '... That the crash actually happens without an active RDP session is weird. Maybe a different component in our app is also depending on that DLL.'  as there is nothing we can do to find the issue. All my drivers are up to date, no rdp connections in use or even added. 


I use Royal TS 4 every day and would like to upgrade to 5, however with the random crashes it is not feasible.


Regards,

I'm sorry you are experiencing issues. As mentioned above, the problematic DLL causing the crash is not part of Royal TS. We have dependencies on external libraries (Microsoft and 3rd party) and it seems that this particular library is part of the RDP component which ships with Windows. I've seen other users (using similar tools as Royal TS taking advantage of the RDP ActiveX control) with the same issue. It seems to be graphics related and for some, updating the graphics driver or tweaking the RDP settings improved the situation. That the crash actually happens without an active RDP session is weird. Maybe a different component in our app is also depending on that DLL.


Hi,


I did a bit of research and couldn't find much but it seems to be related to codecs used by Microsofts RDP ActiveX control which ships with Windows. Royal TS is using this control and configures it for operation. Maybe it's related to some of the performance settings (like Desktop composition or DirectX). You should also check if there's a newer version of the graphics driver available for your system.


Since this is a "black box" (closed source) component from Microsoft, we do not have any insights what exactly goes wrong. I'm afraid that we can only provide some troubleshooting tips as above...


Regards,
Stefan
