Interface (Stabilization)

Stabilization inherits from StabilizationQuery.

It provides APIs to set video stabilization.

Video stabilization can be set only when the session has a recording stream (VideoOutput). Among the enums of VideoStabilizationMode, the HIGH mode only takes effect when the resolution set in Profile is 1920×1080.

NOTE

• The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
• The initial APIs of this interface are supported since API version 11.
