If configured with --enable-ext-tile, the codec uses an alternative tile coding syntax in the bitstream. Changes include:: - The maximum number of tile rows and columns is extended to 1024 each. - The minimum tile width/height is 64 pixels (1 superblock). - A tile copy mode is added where a tile directly reuse the coded data of a previous tile - The meaning of the tile-columns and tile-rows codec parameters are overloaded to mean tile-width and tile-height in units of 64 pixels. - All tiles should now be independent, including rows within the same columns, so large scale parallel, or independent decoding is possible. - vpxdec also gained the options to decode only a particular tile, tile row, or tile column. Changes without --enable-ext-tile: - All tiles should now be independent, including rows within the same columns, so large scale parallel, or independent decoding is possible. - vpxenc default tile configuration changed to use 1 tile column.
