1. One or more computer-readable media having stored thereon computer-executable instructions for causing one or more processing units, when programmed thereby, to perform operations, the one or more computer-readable media being selected from the group consisting of volatile memory, non-volatile memory, and storage, the operations comprising:
receiving encoded data as part of a bitstream; and
decoding the encoded data with wavefront parallel processing (“WPP”) enabled, wherein the decoding reconstructs a picture, including, for a palette decoding mode, predicting a palette for an initial unit in a current WPP row of the picture using previous palette data from a previous unit in a previous WPP row of the picture, wherein the previous palette data from the previous unit in the previous WPP row includes, for each of C colors, one or more color component values, and wherein C is limited by a threshold count for the previous palette data from the previous unit in the previous WPP row.
