Abstract: Temporal motion vector prediction control is described in video coding. In one example, a method includes receiving a plurality of frames representing encoded video, parsing an uncompressed header for each frame, determining whether a temporal motion vector prediction command is included within the parsed uncompressed header of a first frame, selecting a reference frame from a reference list of frames, retrieving motion vector information from the selected reference frame, performing temporal motion vector prediction on the first frame corresponding to the parsed uncompressed header if a temporal motion vector prediction command is included within the parsed header to form a motion predicted frame, applying a loop filter to the motion predicted frame, and rendering the frame as decoded video.

Abstract: The present techniques include deriving a threshold to maintain an encoding bitrate and determining a percentage of change of a current frame N based on an impact to a bitrate budget. The present techniques also include marking a reference frame N?1 as non-referenceable in response to the percentage of change being smaller than the threshold and encoding a static portion of frame N as a skip and encoding a non-static portion of frame N by referencing the reference frame N?1. Finally, the present techniques include overwriting a surface of the reference frame N with portions of the reference frame N?1 that have changed as compared to frame N.
