VFW_E_DVD_STREAM_DISABLED
Meaning
Windows documents VFW_E_DVD_STREAM_DISABLED as “The specified stream is disabled and cannot be selected”. Here, the application tries to select an audio, subpicture or angle stream that the current DVD state marks disabled.
Relevant contract
Code-specific boundary: VFW_E_DVD_STREAM_DISABLED narrows the investigation to the enabled/disabled state of the selected authored stream and the command that attempted to activate it. Preserve the DVD domain, title/menu location and graph topology from the same attempt so a later navigation error is not mistaken for the original condition.
Start with the DVD Navigator, graph builder, decoder inventory and renderer topology.
Evidence worth preserving
- Evidence 1: stream type, index and enabled flag.
- Evidence 2: current title, VTS and domain.
- Evidence 3: stream-count and stream-change events.
Conditions that can produce it
- Cause 1: the authored stream is unavailable in the current title.
- Cause 2: a stream-change event invalidated the prior selection.
- Cause 3: the application uses a global index across title sets.
Retry and recovery
Retry rule: Retry after the target stream is enabled in the current title or another valid stream is chosen.
Correction strategy
- Action 1: refresh enabled-stream lists on DVD events.
- Action 2: prevent selection of disabled entries.
- Action 3: preserve user preference and apply it only when a compatible stream becomes enabled.
Example incident
A preferred subtitle index exists on one title but is disabled on the next; validating the title-specific stream map avoids it.
How it differs from nearby results
VFW_E_DVD_NO_ATTRIBUTES means metadata for a requested stream is unavailable; it means the stream is known but cannot currently be selected.
