This is the first patch to add superblock (32x32) coding order capabilities. It does not yet do any mode selection at the SB level, that will follow in a further patch. This patch encodes rows of SBs rather than MBs, each SB contains 2x2 MBs. Two intra prediction modes have been disabled since they require reconstructed data for the above-right MB which may not have been encoded yet (e.g. for the bottom right MB in each SB). Results on the one test clip I have tried (720p GIPS clip) suggest that it is somewhere around 0.2dB worse than the baseline version, so there may be bugs. It has been tested with no experiments enabled and with the following 3 experiments enabled: --enable-enhanced_interp --enable-high_precision_mv --enable-sixteenth_subpel_uv in each case the decode buffer matches the recon buffer (using "cmp" to compare the dumped/decoded frames). Note: Testing these experiments individually created errors. Some problems were found with other experiments but it is unclear what state these experiments are in: --enable-comp_intra_pred --enable-newentropy --enable-uvintra This code has not been extensively tested yet, so there is every likelihood that further bugs remain. I also intend to do some code cleanup & refactoring in tandem with the next patch that adds the 32x32 modes. Change-Id: I1eba7f740a70b3510df58db53464535ef881b4d9
