VFW_E_NOT_CONNECTED

VFW_E_NOT_CONNECTED is a DirectShow HRESULT. The method was called on a pin, filter or connection-dependent interface before the necessary graph edge had been created, or after it had been disconnected during teardown or reconfiguration.

What to inspect

Use IPin::ConnectedTo to confirm that the pin still has a peer.
Check the order of asynchronous graph building and teardown; another thread may have removed the connection.
Connect the required pins through the filter graph manager before invoking operations that depend on streaming or negotiated allocator state.

A successful filter creation does not imply that all of its pins are connected. Inspect the graph topology explicitly.
