VFW_E_DVD_RENDERFAIL
Meaning
Windows documents VFW_E_DVD_RENDERFAIL as “DVD-Video playback graph building failed”. Here, IDvdGraphBuilder cannot construct a complete playback graph for the selected DVD volume.
Evidence worth preserving
- Evidence 1: AM_DVD_RENDERSTATUS fields.
- Evidence 2: filters added and failed stream counts.
- Evidence 3: first connection or activation HRESULT preceding the aggregate result.
Relevant contract
This result belongs to the legacy DirectShow DVD Navigator contract. DVD state is authored and stateful: domains, user-operation controls, titles, menus, streams, command objects and graph construction each impose different preconditions.
Start with the DVD Navigator, graph builder, decoder inventory and renderer topology.
Conditions that can produce it
- Cause 1: source, decoder or renderer connections fail.
- Cause 2: disc content cannot be parsed sufficiently to expose streams.
- Cause 3: renderer flags conflict with filters already in the graph.
Correction strategy
- Action 1: interpret the detailed render status rather than treating this code as the root cause.
- Action 2: remove incompatible pre-existing filters.
- Action 3: repair missing decoders, devices or disc access indicated by the status.
Example incident
A DVD build returns it and AM_DVD_RENDERSTATUS shows no compatible video decoder; installing the approved MPEG-2 decoder addresses the actual cause.
Retry and recovery
Retry rule: Retry after correcting the specific failed stream or graph condition; blindly rebuilding the same graph is unlikely to help.
How it differs from nearby results
VFW_E_DVD_DECNOTENOUGH specifically reports insufficient decoders, while it is the broader graph-building failure.
