Abstract: Techniques for identifying hot spots in a stream of content of an omnidirectional camera for subsequent tracking of the hot spot and presenting the view of the hot spot are described herein. A stream of content of a real space may be received where a frame of the stream content is associated with time information. Locations and identifications of objects within a particular frame of a plurality of frames of the stream of content may be determined based at least in part on an object detection algorithm. Metadata may be generated that includes the identified objects and the locations of the identified objects. The metadata may be interleaved into the stream of content prior to being presented to a user device. An updated view of the content may be presented that corresponds to tracking the object in subsequent frames of content captured by the camera of the real space.

Abstract: Techniques are described for synchronizing encoding processes between encoders. Timestamps are compared between encoders such that offsets can be determined and used by encoders to encode fragments for the same segments of media content.
