A bitstream encoding or decoding job is broken up into a plurality of segments, each of which is independent from subsequent segments and corresponds to a respective fence identifier. The segments are individually processed and progress is indicated using the fence identifiers. In some cases, a first segment is encoded, transmitted, decoded, and processed before a second segment is encoded. As a result, in some cases, segment statuses are more easily tracked, hardware is used more efficiently, end-to-end processing time is reduced, and less communication network bandwidth is used.

Segmented bitstream processing using fence identifiers

Methods and devices are provided for encoding a video stream which comprise encoding a plurality of frames of video acquired from different points of view, generating statistical values for the frames of video determined from values of pixels of the frames, generating, for each of the plurality of frames, a perceptual hash value based on statistical values of the frame and encoding a current frame comprising video acquired from a corresponding one of the different points of view using a previously encoded reference frame based on a similarity of perceptual hashes of the current frame and the previously encoded reference frame.

Identifying long term reference frame using scene detection and perceptual hashing

Reference frame detection using sensor metadata, including: storing a plurality of first frames each corresponding to first metadata, wherein the first metadata for each first frame of the plurality of first frames is based on first sensor data from one or more sensors; generating a second frame corresponding to second metadata based on the one or more sensors; identifying, based on the first metadata of the plurality of first frames and the second metadata, a reference frame of the plurality of first frames; and encoding the second frame based on the reference frame.
