Chroma intra prediction units for video coding

Abstract:

A video decoder can be configured to determine that a block of the video data is formatted in accordance with a 4:4:4 video coding format; determine that the block of the video data is encoded in an intra prediction mode; determine that a smallest chroma intra prediction unit (SCIPU) is disabled for the block in response to determining that the block has the 4:4:4 video coding format; decode the block of the video data based on the determination that the SCIPU is disabled; and output decoded video data comprising a decoded version of the block.
