XR_MSFT_secondary_view_configuration appears deprecated without replacement. Understand impact on spectator view, capture and technical debt.
Direct answer
The OpenXR 1.1.65 registry marks XR_MSFT_secondary_view_configuration as deprecated without replacement. The extension allowed you to enable secondary views, such as an observer camera, and send your own layers at the end of each frame. Products that depend on it for spectator viewing, transmission or capture must detect support at runtime, maintain an alternative path and avoid expanding a dependency that does not have a standardized evolution indicated.
Deprecation does not immediately remove support
Runtimes can continue to expose the extension, but new investments are subject to divergent behavior and limited maintenance.
Spectator view is separate requirement
The user's view and the broadcast camera have different framing, resolution and cost; document the path of each runtime.
Detection must occur at runtime
It's not enough to compile with the headers. Enumerate extensions and enable the feature only where it is actually advertised.
Fallback protects operation
Mirror capture, own camera or engine pipeline can maintain training and support when the secondary view does not exist.
Nexus Reading
Inventory dependencies, freeze deprecated extension expansion and validate alternatives before updating engine or runtime.
FAQ
Did the extension stop working?
Not necessarily. Deprecation indicates that it should not drive new architecture, but runtimes can still support it.
Is there an official replacement?
Registration 1.1.65 marks it as depreciated without replacement.
How to reduce risk?
Detect runtime support, maintain fallback and test capture on each supported headset and engine.
