2013-11-19Use restore_dst_buf in handle_inter_modeJingning Han
There are many places in handle_inter_mode that need to restore the dst buffer pointers, due to buffer pointer swap and early rd search breakout. This commit wraps these operations into an inline function for clean-up. Change-Id: I0462e8c41c8bc3cd8db07395489cac03d8e5be54
2013-11-18Removing raster_block_offset_uint8() function.Dmitry Kovalev
There is no need to use that function, it is much clear to pass offset directly to the buffer. Change-Id: I9026cb0c5094c46f97df5d7f7daeb952f2843b24
2013-11-18Fixed a bug in commit a4a5a210Yaowu Xu
Commit a4a5a210 enabled lossless coding, but the commit incorrectly disabled the usage of skip in encoder even when skip should be used. This commit make sure that skip is enabled even in lossless mode. Change-Id: I276954f952c6ac68f17a316ebc72f09001228a08
2013-11-15Removing vp9_encodeintra.{h, c} files.Dmitry Kovalev
There was only one function in *.c file, so moving it to vp9_encodemb.c. Change-Id: I728859d08b3d6c05c33c1c5b21f0ea1d0e0f83af
2013-11-13Dual buffer encoding for intra modesJingning Han
Overall change (using dual buffer scheme for superblocks of both inter and intra modes) reduces speed 2 runtime: bluesky_1080p at 6000kbps: 263553ms -> 257441ms riverbed_1080p at 8000kbps: 233230ms -> 225308ms. Change-Id: Idf8d70f768a4b0d97b2a8506372c57b7b4022119
2013-11-12Moving q_index from MACROBLOCKD to MACROBLOCK.Dmitry Kovalev
Moving because q_index is used only by encoder. Change-Id: I0b96175614ed4fd3d76ee56a0ba36258e1e896f6

2013-11-11Enable dual buffer rd search and encoding schemeJingning Han
This commit enables the dual buffer rate-distortion optimization and encoding scheme. It stacks the original transform coefficients, quantized levels, and reconstructed coefficients, in the rate- distortion optimization search process, hence eliminates the need to re-run residual generation, forward transform, and quantization in the encoding stage.

2013-11-11Allocate dual buffer sets for encodingJingning Han
Allocate memory space of dual buffer sets that store the coeff, qcoeff, dqcoeff, and eobs. Connect the pointers of macroblock_plane and macroblockd_plane to the actual buffer in use accordingly. Change-Id: I2f0b5f482ca879fae39095013eaf8901db20a5a4

2013-11-11Moving {sb, mb, b, ab}_index from MACROBLOCKD to MACROBLOCK.Dmitry Kovalev
We use {sb, mb, b, ab}_index only inside encoder, so moving them into appropriate data structure. Change-Id: Ib5c1036716354d9d321e11a60c1634c1cb8f9716

2013-11-05Localizing NEARESTMV special cases in the code.Dmitry Kovalev
Removing special case handling from vp9_tree_probs_from_distribution(), tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing inter_mode_offset() function with macro INTER_OFFSET which is used now for vp9_inter_mode_tree definition. Change-Id: Iff75a1499d460beb949ece543389c8754deaf178

2013-11-05Merge "Avoid mv cost check for invalid mv values"Jingning Han
2013-11-04Avoid mv cost check for invalid mv valuesJingning Han
The compound inter prediction could potentially run with initial motion vectors of invalid value and check the mv_cost, which triggers overheap read. This commit resolves this issue by forcing a motion vector value check for compound inter modes of both superblock and sub8x8 block sizes. Change-Id: I4f4fc19ce83c8272782bc382f12c82a3f03212fc
2013-11-04Splitting partition_probs array into two arrays.Dmitry Kovalev
We only update partition_probs for inter frames but they are constant for key frames. It is not necessary to have constants inside frame context and copy them every time. This change reduces FRAME_CONTEXT size by at least 48 bytes. Change-Id: If70a53be51043f37fe7d113853217937710932a7
2013-11-03Fix the use case of plane_block_idx in sub8x8 RDJingning Han
This commit fixes the use case of plane_block_idx, which determines the plane (Y/U/V) index based on block index. When block idx >= 4 in sub8x8 block loop, it should be of chroma components. Change-Id: I072705aa7b35445524ac607089ca8ce54b7ba478

2013-10-30Enable all-zero coeff block index for sub8x8 blkJingning Han
This commit makes zcoeff_blk cache the case where the entire block is quantized to be zero (without applying zero-forcing) in the rate- distortion optimization loop, and skip the forward DCT, quantization, inverse DCT, and reconstruction process in the encode_block stage. It now works for all the block sizes, including sub8x8 blocks. Change-Id: I5ae60a9c436ba3637d11666733554bec4580ef98
2013-10-29Fix x_offset_q4/y_offset_q4 calculationYunqing Wang
"<< SUBPEL_BITS" needs to be added in the calculation. Call set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4. Change-Id: Ied130ea771510e918f51cd1dc3abe57f4c0962b5

2013-10-28Removing is_intra_mode() function.Dmitry Kovalev
It is enough to check just block type: intra or inter. Intra block implies intra prediction mode, and inter block implies inter mode. Change-Id: I3cf98731a3935f670a3cd8e2b2443483eb944be4

2013-10-23Use inter mode flag in super_block_yrdJingning Han
Use a flag variable to determine if coded in inter mode, thus avoiding multiple inter mode checks in super_block_yrd. Change-Id: I0ef998b2811c38e185a2e0583f0f636cee45d2cf
2013-10-22Improve scale_factors structYunqing Wang
The ref's scale_factors are set at frame level, and then copied for each partition block. Since the struct members are mostly constant, this patch separated the constant and non-constant members, and reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

2013-10-22Removing quantize_b_4x4 function pointer.Dmitry Kovalev

2013-10-22Prevent left_block_mode stepping into left tileJingning Han
This commit uses left_available flag to decide if the left mode_info struct is available for left_block_mode. As discussed with James Zern (jzern@), this prevents the codec from fetching mode_info from blocks in the left tile, which although effectively not used might present concerns for multi-threaded tile decoding. This is NOT a bit-stream change. Change-Id: I1dc8cf1bcbf056688eee27c7bc5706ac4b4e0125
2013-10-21Using stride (# of elements) instead of pitch (bytes) in fdct4x4.Dmitry Kovalev
