Many a times I do get this questions from my varied customers and colleagues and I cannot answer them instantly or even after looking here and there for a day. So I just wanted to blog it.
Please see the MSDN link http://msdn.microsoft.com/en-us/library/dd388394(v=VS.85).aspx for the steps in getting the logs.
Here are some steps to remember:
DebugRoot = SOFTWARE\Microsoft\DirectShow\Debug (Windows Vista or later)
Registry Location = HKEY_LOCAL_MACHINE\<DebugRoot>\<ModuleName>\<MessageType>
ModuleName = Quartz.dll
MessageType = TRACE
I would recommend making two tests by setting TRACE to:
1. 0x00000003 and
So you get two quartz logs.
