Mode dependent primary and secondary transforms
A method and apparatus for signaling a transform type used to encode a current block in an encoded video bitstream includes determining an intra prediction mode of the current block, and determining whether the intra prediction mode satisfies a predetermined condition, wherein in response to determining that the predetermined condition is satisfied, the transform type is signaled in the encoded video bitstream, and in response to determining that the predetermined condition is not satisfied, the transform type comprises a default transform type, and the transform type is not signaled in the encoded video bitstream.
