Data Flow in the Filter Graph

This topic describes how media data moves through the filter graph. It is intended for developers who are writing their own custom filters. Application developers generally do not have to worry about the subjects covered here.

The following topics focus on the shared memory transport, using the IMemInputPin and IMemAllocator interfaces:

• Push versus Pull
• Thread Usage
• Generating New Samples
• Processing a Sample
• End of Stream
• Flushing
• Critical Sections in Filters
• Base Classes for Data Flow
