VFW_S_RESOURCE_NOT_NEEDED

DirectShow resource is no longer required

VFW_S_RESOURCE_NOT_NEEDED is HRESULT 262736 (0x00040250) from Video for Windows. The documented description is “The resource specified is no longer needed.” The high-order severity bit is clear, so this is a success result, but it carries more information than plain S_OK.

The media operation completed with information that the specified resource is not needed for the current graph state or operation.

Where the result is encountered

This result can appear in allocator or renderer resource management; record the producing interface and method.
This result can appear in graph reconfiguration; record the producing interface and method.
It can appear in cleanup paths that release obsolete media resources; record the producing interface and method.

State to verify

The central question is whether the resource is not referenced by an active pin, pending sample, or asynchronous operation.

Diagnostic sequence

Capture the raw HRESULT 0x00040250 immediately after the returning method and record whether the caller used SUCCEEDED, FAILED, equality testing, or exception translation.

Evidence to preserve

Preserve resource type and owner filter.
Preserve graph state.
Preserve outstanding sample and allocator counts.
Preserve reference count or handle lifetime.
Preserve transition that made the resource unnecessary.

Correct handling, retry, and recovery

Release or stop using the resource according to its ownership contract. Do not interpret this as permission to free an object still referenced by another component.

Difference from nearby HRESULT values

VFW_S_STREAM_OFF reports a disabled stream; it reports that a particular resource can be omitted or retired.

Practical validation scenario

A graph switches to a renderer path that does not use the old surface allocation. The component receives it, waits for outstanding samples, and releases the obsolete allocation once.
