2013-10-11Experimental rate control change.Paul Wilkins
When the codec in VBR (or cq) mode hits its max q limits and is struggling to hit a target bandwidth, the bit target per frame collapses. In the first instance normal frames cap out at the maximum allowed Q and then the ARF and GFs do the same. This latter behavior is not generally desirable as GFs and ARFs are only effective from a quality and data rate perspective if they have at lease some level of -Q delta compared to the surrounding frames. In this patch I define a separate max Q for GFs and ARFs that is derived from but somewhat lower than that defined for normal frames. In effect there is a minimum Q delta that will always be available for GFs and ARFs regardless of the target rate and MAXQ setting. This may of course mean that the absolute lowest rate obtainable for a given clip is somewhat higher. Change-Id: I268868b28401900d0cd87e51e609cd3b784ab54a

2013-10-10Removing vp9_idct4_1d_sse2 function.Dmitry Kovalev
We have two SSE2-optimized functions for idct4_1d: vp9_idct4_1d_sse2 <-- removing this one idct4_1d_sse2 vp9_idct4_1d_sse2 was used only by the following functions which already have SSE2 optimized variants: vp9_idct4x4_16_add_c -> vp9_idct4x4_16_add_see2 idct8_1d -> vp9_idct8x8_{16, 10, 1}_see2 vp9_short_iht4x4_add_c -> vp9_short_iht4x4_add_see2 Change-Id: Ib0a7f6d1373dbaf7a4a41208cd9d0671fdf15edb

2013-10-10SSE2 8-tap sub-pixel filter optimizationYunqing Wang
To ensure fast encoding/decoding on devices without ssse3 support, SSE2 optimization of sub-pixel filters was done. Test using 1080p clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps with sse2 filters, and ~15fps with c filters. Change-Id: Ie2088f87d83a889fba80a613e4d0e287aadd785c

2013-10-10Re-design rate-distortion cost tracking buffersJingning Han
This commit re-designs the per transformed block rate-distortion costs tracking buffers. It removes redundant buffer usage, makes the needed context memory allocation per VP9_COMP instance and reuses the same buffer sets inside the rate-distortion optimization search loop, thereby avoiding repeatedly requiring memory space. It reduces speed 0 runtime: bus at 2000 kbps from 166763ms to 158967ms, football at 600 kbps from 246614ms to 234257ms. Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up for speed 1 and 2 settings. This does not change compression performance. Change-Id: I363514c5276b5cf9a38c7251088ffc6ab7f9a4c3

2013-10-09Deprecate the use of PARTITION_INFO from encoderJingning Han
Use b_mode_info to store the inter prediction mode of sub8x8 block, in replacement of the use of partition_info. Remove redundant buffer update for partition_info. For bus_cif at 2000 kbps, this seem to make speed 0 about 1% faster. Change-Id: Id1b3be45e75a24fb4b42335ac480c23e440978f6

When all coefficients are zeros, skip the corresponding 1-D inverse transform. This practice has been used in the SSE2 implementation of inverse 32x32 DCT. This commit imports this algorithm into the C code. Change-Id: I0f58bfcb183a569fab85d524d5d9cf8ae8653f86

We already have itxm_add member in MACROBLOCKD structure. Both inv_txm4x4_1_add and inv_txm4x4_add are just its special cases for different eob values. But eob logic is already implemented in vp9_iwht4x4_add and vp9_idct4x4_add (that's why also removing inverse_transform_b_4x4_add). Change-Id: I80bec9b6f7d40c5e5033c613faca5c819c3e6326
