| 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. |
