1. An apparatus, comprising: a video encoder including a transformer and a quantizer, the video encoder configured to encode at least a block using a transform selected from a plurality of transforms and to encode at least a second block using a second transform selected from an adaptively updated plurality of transforms, wherein the transformer is configured to determine the adaptively updated plurality of transforms by adaptively updating the plurality of transforms, after one or more pictures are encoded, based on residue information from the encoded one or more pictures, and wherein adaptively updating the plurality of transforms includes the transformer adaptively updating a basis of at least a transform of the plurality of transforms based on the residue information from the encoded one or more pictures.
