Compiled TvService crashes when tuning

mjs · 2007-12-20, 22:24

Hi,

I tried to use/debug my own compiled versions of TvService but I get a FatalExecutionEngineError (0xc0000005) at address "0x7f5350c6". The debugger stops at the following line

Code:

enumMedia.Next(20, mediaTypes, out fetched);

in function AddAndConnectBDABoardFilters of the class TvCardDvbBase.

Any idea why this happens?

I am using VS2005 + SP1 + Vista-Fix for SP1 on Vista AMD64.

Regards,
Mark

I had to change the "Target Platform" from "Any CPU" to "x86" to work around this problem. This has the nice side-effect that I can enable native debugging.

Anyway, it seems to be a problem in the .NET runtime for x64 and not a problem of MediaPortal's code because IntPtr members don't automatically get an 8-Byte-Alignment. IOW: The AM_MEDIA_TYPE structure has a size of 88 bytes (instead of 80 bytes) on x64 and 72 bytes on x86. Any idea how to fix this problem?

EDIT: I just tried to temporarily add two member variables to this structure but this doesn't help either. There seems to be another problem too.

Regards,
Mark
