Abstract: Various implementations disclosed herein include devices, systems, and methods that adjust a brightness characteristic of virtual content (e.g., virtual objects) and/or real content (e.g., passthrough video) in views of an XR environment provided by a head mounted device (HMD). The brightness characteristic may be adjusted based on determining a viewing state (e.g., a user's eye perception/adaptation state). A viewing state, such as a user's eye perception/adaptation state while viewing a view of an XR environment via an HMD, may respond to a brightness characteristic of the XR environment that the user is seeing, which is not necessarily the brightness characteristic of the physical environment upon which the view is wholly or partially based.

Abstract: Improved media processing techniques includes media data formats with a “convenience” sample having both a snapshot and a delta description of a scene at the same media time. In other examples, improved media processing techniques include creating a temporary media sample having a merged snapshot or a merged delta in a context of a pre-render thread to improve performance of rendering performed in a context of a separate rendering thread.
