When this method is called, the pin is beginning to end a flush operation. It should perform the following steps.

Ensure that your filter will not push any additional data. (To do this, synchronize with a thread, stop it pushing, and discard any queued data.)

Re-enable the IMemInputPin::Receive method by clearing the internal flushing flag.

Pass the EndFlush method downstream by calling the method on the connecting input pin.

This method is implemented in the base classes by CBaseInputPin::EndFlush.


DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
