A method of encoding video data includes determining that a current block of video data is to be encoded using an intra block copy (BC) mode and constrained intra prediction, determining one or more reference blocks that may be used for encoding the current block using the intra BC mode, wherein each of the one or more reference blocks is encoded with an intra prediction mode, and encoding the current block of video data using the intra BC mode and at least one of the determined one or more reference blocks.
