VFW_E_NO_COPP_HW
Meaning
Windows documents VFW_E_NO_COPP_HW as “The current display device does not support Content Output Protection Protocol (COPP) H/W”. Here, the current VMR and display device cannot establish a hardware COPP session for protected video output.
Relevant contract
Start with the renderer, graphics driver, display connection and negotiated surfaces.
Conditions that can produce it
- Cause 1: the graphics driver does not support COPP.
- Cause 2: the VMR is not connected to a display device yet.
- Cause 3: the active output path or adapter does not expose certified protection.
Evidence worth preserving
Record lengths and hashes instead of raw content when the incident includes display identifiers, protected-content state, driver details and media paths.
- Evidence 1: IAMCertifiedOutputProtection availability.
- Evidence 2: adapter, connector and driver state.
- Evidence 3: renderer connection state and COPP capability query.
Correction strategy
- Action 1: test support before beginning protected playback.
- Action 2: connect the renderer to the intended display before COPP negotiation.
- Action 3: choose a certified output path or report the protection requirement clearly.
Retry and recovery
Retry rule: Retry after changing to a COPP-capable connected display path; repeated negotiation on unsupported hardware cannot succeed.
How it differs from nearby results
VFW_E_COPYPROT_FAILED can describe failure while enabling protection on capable components, whereas it says the required hardware protocol is unavailable.
Example incident
A protected stream is opened on a basic virtual display adapter that exposes no COPP interface; selecting a certified physical adapter avoids it.
