VFW_E_VMR_NO_DEINTERLACE_HW

Exact result and bit fields

VFW_E_VMR_NO_DEINTERLACE_HW has the unsigned HRESULT value 2147746456 (0x80040298) and the signed 32-bit representation -2147220840. AllStat describes it as “The VMR could not find any de-interlacing hardware on the current display device”. In the operation that produces this result, the VMR cannot find hardware support for the requested deinterlacing operation on the current display device.

The high bit is set, so this value is a failure HRESULT. Its facility field is 4 (FACILITY_ITF) and its low code is 664 (0x0298). These fields classify this result, but they do not identify which filter, thread, device, file or graph generation returned it.

Contract boundary

This result is tied to a legacy rendering or graphics-capability boundary. The result should be diagnosed from the selected renderer, adapter, driver, surface contract and graph topology rather than from the file extension alone.

The practical owner to locate for this HRESULT is the renderer, graphics driver, display connection and negotiated surfaces. When handling this result, capture the native result before a wrapper replaces it with a generic exception, and keep the graph generation or object identity with the record.

Conditions that can produce it

  • Cause 1 for this HRESULT: the adapter exposes no supported deinterlace mode.
  • Cause 2 for this HRESULT: the input format or resolution is outside hardware capability.
  • Cause 3 for this HRESULT: remote or virtual display paths hide acceleration features.

Evidence worth preserving

Log the interface and method, filter CLSID and friendly name, process and thread, graph state, connected pin names, media-type summary, renderer or device identity where relevant, and the first preceding HRESULT. Record lengths and hashes instead of raw content when the incident includes display identifiers, protected-content state, driver details and media paths.

  • Evidence 1 for this HRESULT: adapter and monitor identity.
  • Evidence 2 for this HRESULT: input interlace flags, dimensions and frame rate.
  • Evidence 3 for this HRESULT: enumerated deinterlace modes and driver version.

Step-by-step diagnosis

  1. Capture it at the first native return, not only at the top-level playback failure.
  2. identify the exact graph stage described here: the VMR cannot find hardware support for the requested deinterlacing operation on the current display device.
  3. compare the live object state, topology and input with the documented interface preconditions.
  4. Before changing filters, drivers, registry data or media for this HRESULT, collect the code-specific evidence below.
  5. Test one evidence-backed the correction on the smallest reproducible graph.
  6. Verify that the corrected run no longer returns it and does not merely replace it with a nearby HRESULT.

Correction strategy

  • Action 1 for this HRESULT: choose a supported mode or software deinterlacing path.
  • Action 2 for this HRESULT: disable the feature when capability enumeration is empty.
  • Action 3 for this HRESULT: requery capabilities after display-device changes.

Retry and recovery

Retry rule for this HRESULT: Retry after selecting another adapter, format or deinterlacing implementation. A safe it retry must use a changed capability, state, object generation or input. While recovering from it, preserve cancellation and avoid replaying side effects when the original operation may have partially completed.

Example incident

A player requests adaptive hardware deinterlacing inside a remote session where no modes enumerate; falling back to software avoids it. This example keeps the diagnosis at the specific the boundary instead of treating every DirectShow failure as a codec reinstall problem.

How it differs from nearby results

VFW_E_DDRAW_CAPS_NOT_SUITABLE is a broad legacy graphics-capability mismatch, while it specifically reports absent VMR deinterlace acceleration. Keep those cases separate in telemetry, UI messages and retry policy because their next actions are different.

Implementation notes

Code that handles it should preserve the original HRESULT, the failed stage and an opaque correlation identifier. After it, do not infer success from partial graph construction, and do not continue using interfaces retained from a graph or device generation that has already changed.

Operational remediation for this HRESULT should favor supported component installation, device configuration and documented DirectShow calls. Manual registry or driver changes are appropriate only when the collected evidence for this HRESULT points to that layer and a rollback is available.
