摘要：
Methods and apparatus are provided for constrained transforms for video coding and decoding having transform selection. An apparatus includes a video encoder for encoding at least a block in a picture by selecting a particular transform from at least a first transform and a second transform that is different than the first transform, and applying the particular transform to a residue of the block. Transform coefficients for the second transform are selected responsive to a deblocking filter that is present in the video encoder.
