In some implementations, a method includes: determining a complexity value for first image data associated with of a physical environment that corresponds to a first time period; determining an estimated composite setup time based on the complexity value for the first image data and virtual content for compositing with the first image data; in accordance with a determination that the estimated composite setup time exceeds the threshold time: forgoing rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period; and compositing a previous render of the virtual content for a previous time period with the first image data to generate the graphical environment for the first time period.

A method for providing media content within a media distribution network. The method comprises transforming source media content into an interim format, thereby providing transformed content. Furthermore, the method comprises storing the transformed content on at least one core storage unit. In addition, the method comprises receiving a request for the source media content from a client. The method further comprises encoding the transformed content or intermediate coded content derived therefrom into encoded content suitable for transmission over a core network and/or an edge network, as well as sending the encoded content via the core network and/or the edge network to the client.

A method, apparatus and computer program product are provided to signal and store compressed point clouds in video encoding. The method, apparatus and computer program product may be utilized in conjunction with a variety of video formats. Relative to encoding of compressed point clouds, the method, apparatus and computer program product access a point cloud compression coded bitstream and cause storage of the point cloud compression coded bitstream. The point cloud compression coded bitstream comprises a texture information bitstream, a geometry information bitstream, and an auxiliary metadata bitstream. Relative to the decoding of compressed point clouds, the method, apparatus and computer program product receive a point cloud compression coded bitstream and decode the point cloud compression coded bitstream.

Disclosed are a video processing method and apparatus, and a storage medium. The method includes: receiving a selection instruction of having selected one or more video streams or key frames of the one or more video streams to be browsed; setting video stream thumbnails generated from the one or more video streams or key frame thumbnails generated from the key frames to a scene thumbnail to generate a picture layout stream according to the selection instruction, where the scene thumbnail is generated according to a scene displayed in an augmented reality/virtual reality (AR/VR) interface; and presenting the picture layout stream in the VR/AR interface, and providing a virtual layout interface of multiple video stream pictures.

Methods and devices for encoding and decoding data representative of a 3D scene are disclosed. A set of first patches is generated from a first MVD content acquired from a first region of the 3D scene. A patch is a part of one of the views of the MVD content. A set of second patches is generated from a second MVD content acquired from a second region of the 3D scene. An atlas packing first and second patches is generated and associated with metadata indicating, for a patch of the atlas, whether the patch is a first or a second patch At the decoding side, first patches are used for rendering the viewport image and second patches are used for pre-processing or post-processing the viewport image.

The present invention is applicable to the technical field of panoramic videos. Provided are a panoramic video clip method, apparatus and device, and a storage medium. The method comprises acquiring a panoramic video photographed by means of a panoramic camera, and recording an advancing-direction viewing angle of the panoramic camera during moving photographing; carrying out a frame extraction operation on the acquired panoramic video to obtain a corresponding panoramic video frame, carrying out significant target detection on the panoramic video frame, tracking a detected significant target by using a preset target tracking algorithm, and acquiring a viewing angle at which the tracked significant target is located; and clipping the panoramic video according to the advancing-direction viewing angle and the viewing angle at which the significant target is located, so as to generate a target video corresponding to the panoramic video. A panoramic video is automatically clipped, and the fluency of transitions, and the effectiveness and the degree to which content in a target video is interesting are also ensured.
