    Abstract: A method for flexible encoding is described herein. The method includes selecting a largest coding unit size of a current frame based on a largest coding unit size of a prior frame and determining a coding unit processing order based on heuristics and the largest coding unit size of the current frame. The method also includes determining a rate distortion metric of the current frame based on the largest coding unit size and in response to an exit criteria being met, processing the coding units of the current frame in the coding unit processing order.

    Abstract: Systems, apparatuses and methods may determine, on a per camera basis, an interest level with respect to panoramic video content, identify a subset of cameras in a plurality of cameras for which the interest level is below a threshold, and reduce power consumption in the subset of cameras. Additionally, technology may determine a projection format associated with panoramic video content, identify one or more discontinuous boundaries in the projection format, and modify an encoding scheme associated with the panoramic video content based on the discontinuous boundaries. Moreover, an encoded frame may be assigned to a temporal scalability layer that has a higher priority than a layer to which an asynchronous space warp frame is assigned. Additionally, technology may reduce the encoding complexity of a boundary between an active region and an inactive region in fisheye content.

    Abstract: A video source device for wireless display sharing, including: an encoder operable to dynamically switch between encoding a video full-frame into a first bitstream at a first resolution, and a video sub-frame into a second bitstream at a second resolution, wherein the second resolution is higher than the first resolution; processing circuitry operable to decide between encoding the video full-frame and encoding the video sub-frame based on an amount of available wireless transmission bandwidth, a number of pixels in a changed region of the video full-frame, spatial complexity of a changed region of the video full-frame, temporal complexity of a changed region of the video full-frame, or a category of region change of the video full-frame; and a transmitter operable to wirelessly transmit the first bitstream and the second bitstream to a video sink device.

    Abstract: Methods, apparatuses and systems may provide for a video transmitter that generates a primary bitstream based on a video signal, wherein the primary bitstream is encoded with subsampled chroma information, and detects a static condition with respect to the video signal. Additionally, a plurality of auxiliary bitstreams may be generated, in response to the static condition, based on the video signal. Each of the plurality of auxiliary bitstreams may be encoded with full resolution chroma information. In one example, a video receiver may detect that the auxiliary bitstreams are associated with the primary bitstream, decode the primary bitstream and the plurality of auxiliary bitstreams to obtain luma information and the full resolution chroma information, and multiplex the luma information with the full resolution chroma information.
