Abstract
Disclosed are systems and techniques for efficient real-time codec encoding of video files. In one embodiments, the techniques include receiving one or more intra-prediction modes, each having a corresponding cost; calculating a first cost of a chroma-from-luma intra-prediction mode; calculating a second cost of the chroma-from-luma intra-prediction mode; and calculating a final cost based on the first cost and the second cost. The techniques also include selecting a final intra-prediction mode; generating, based on the selected final intra-prediction mode, a block of predicted pixels that approximates a block of source pixels of an image frame; and encoding a first alpha value in a bitstream.
