Abstract

Video coding using a constructed reference frame may include generating, by a processor in response to instructions stored on a non-transitory computer readable medium, an encoded video and outputting an output bitstream. Generating the encoded video includes receiving an input video stream, generating a constructed reference frame, generating an encoded constructed reference frame by encoding the constructed reference frame, including the encoded constructed reference frame in an output bitstream such that the constructed reference frame is a non-showable frame, generating an encoded frame by encoding a current frame from the input video stream using the constructed reference frame as a reference frame, and including the encoded frame in the output bitstream.
