Abstract
A video coder can be configured to determine an intra-prediction mode for a block of video data, identify a most probable transform based on the intra-prediction mode determined for the block of video data, and code an indication of whether the most probable transform is a transform used to encode the block of video data. The most probable transform can be a non-square transform.
