Notes:
|
|
The derived class is meant to do most work to initialize streaming
|
|
in AllocateStreamingResources rather than when types are set.
|
|
|
|
This centralizes the work to one
|
|
clear place based on the types set for all streams.
|
|
|
|
The derived class implements locking.
|
|
|
|
The derived class implements the IUnknown methods
|
|
|
|
Usage example (1 input and 1 output) :
|
|
class CMyDMO : public IMediaObjectImpl<CMyDmo, 1, 1>,
|
|
...
