Abstract: Systems, methods, and non-transitory computer-readable media can determine a request for a content item from a computing device. One or more view directions of a user operating the computing device can be predicted during playback of the content item. One or more frames of the content item are quantized based at least in part on the predicted view directions.

Abstract: Systems, methods, and non-transitory computer-readable media can cause a content item to be presented through a display screen of the computing device, the presentation of the content item beginning at a first time position. A determination is made that a user operating the computing device has adjusted the presentation of the content item to correspond to a second time position. A thumbnail preview that corresponds to the second time position is obtained from a composite preview video associated with the content item.

Abstract: Systems, methods, and non-transitory computer readable media are configured to receive a media item. The media item can be split into a plurality of segments. The plurality of segments can be subjected to a plurality of distributed prepublication processing stages. One or more stage progress reports can be received. Each of the one or more stage progress reports can indicate an extent complete of one of the plurality of distributed prepublication processing stages for one of the plurality of segments. An overall extent complete can be calculated with respect to the media item based on the one or more stage progress reports.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain a spherical media content item that captures at least one scene from a plurality of different positions. A three-dimensional shape having a plurality of faces is determined, each face being associated with a respective set of original boundaries. A respective set of expanded boundaries for one or more of the plurality of faces is determined. Respective portions of the spherical media content item are mapped to each of the one or more faces, wherein a first portion of the spherical media content item is mapped to a first face having a set of expanded boundaries.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain a spherical media content item that captures at least one scene from a plurality of different positions. A three-dimensional object with a plurality of faces that converge at a point is determined. At least a first portion of the spherical media content item is mapped to at least a first face in the plurality of faces.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a first position corresponding to a user focal point during presentation of a given scene of a content item. A celestial representation of the given scene is determined. The celestial representation identifies one or more audio-based points of interest in the scene. A second position corresponding to the user focal point is determined based at least in part on the celestial representation and the first position. The second position is predicted to be the position of the user focal point during presentation of the scene.

Abstract: Systems, methods, and non-transitory computer-readable media can present one or more base segments of a first stream of a content item in a viewport interface, the content item being composed using a set of streams that each capture at least one scene from a particular direction, wherein the viewport interface is provided through a display screen of the computing device. A determination is made that a direction of the viewport interface has changed to a different direction during playback of a first base segment of the first stream. One or more offset segments of a second stream that correspond to the different direction are presented in the viewport interface, the offset segments being offset from the set of base segments of the first stream.
