Abstract: Innovations in reconstruction and rendering of panoramic video are described. For example, a view-dependent operation controller of a panoramic video playback system receives an indication of a view direction for an application and, based at least in part on the view direction, identifies a section of a picture of panoramic video in an input projection. The view-dependent operation controller limits operations of a color converter, video decoder, and/or streaming controller to the identified section. In this way, the panoramic video playback system can avoid performing operations to reconstruct sections of the picture of panoramic video that will not be viewed. As another example, a mapper of a panoramic video playback system re-projects at least some sample values in an input flat projection towards a center location for a view direction, producing an output flat projection, which an application can use to generate one or more screen projections.

Abstract: Innovations in reconstruction and rendering of panoramic video are described, including the use of a platform rendering engine to provide a screen projection based on a view direction specified for an application through an interface. For example, based at least in part on the view direction specified for the application, at least a section of panoramic video in an input projection is identified. At least some of sample values of the at least a section of the picture of panoramic video in the input projection are mapped to a screen projection. The screen projection is output for display to a buffer for the application. Thus, an application may use panoramic video, including updating a view direction, without itself having to render a screen projection for the panoramic video.

Abstract: A facility for managing a media player is described. In one example facility, the facility discerns direction from an application program specifying a presentation of media player controls for the media player. Based at least in part on the discerning, the facility causes the media player to be displayed, including a visual user interface for the media player in which media player controls are presented in accordance with the discerned direction.
