1. A video codec comprising:
a memory; and
a processor operably coupled to the memory and configured to:
compute a reconstructed pixel based on a residual pixel and a first prediction pixel; and
compute a second prediction pixel in a directional intra prediction mode based on the reconstructed pixel, wherein the first prediction pixel and the second prediction pixel are located in a same block of a video frame.
