2015-02-11Add ref frame rate cost to non-RD mode decisionJingning Han
This commit adds a heuristic rate cost of reference frame to the non-RD mode decision. It improves the compression performance of speed -6 by 0.31% and speed -5 by 0.69%. Change-Id: If7f3b45519d49b2cb640bcb7316a254efc8be446
2015-02-10Move computation up to frame levelYaowu Xu
This is to avoid redo the same calculation repeatly, and also allow easier adjustments for further experiments. This commit shall have no effect on quality/compression. Change-Id: I4460acf5c808ff5518da18d21e002c5da58af857

2015-02-10Auto-adaptive encoder frame resizing logicAdrian Grange
Note: This feature is still in development. Add an option for the encoder to decide the resolution at which to encode each frame. Each KF/GF/ARF goup is tested to see if it would be better encoded at a lower resolution. At present, each KF/GF/ARF is coded first at full-size and if the coded size exceeds a threshold (twice target data rate) at the maximum active Q then the entire group is encoded at lower resolution. This feature is enabled in vpxenc by setting: --resize-allowed=1 In addition, if the vpxenc command line also specifies valid frame dimensions using: --resize-width=XXXX & --resize_height=YYYY then *all* frames will be encoded at this resolution.

2015-02-10Fix block partition size in fill_mode_info_sbJingning Han
This commit fixes the sub block partition size used in fill_mode_info_sb. Previous implementation effectively disabled the rectangular block sizes. This commit resolved this issue. Change-Id: Ic1c383ab0a9a2e7d59e85b388093f1f1f94d1e7f

2015-02-09Set the maximum decode threads to be 8.hkuang
This will fix the frame parallel decode hang on windows due to not enough semaphores. This will also make the frame parallel decode safer as the number of frame buffers could only support maximum 8 threads. Change-Id: Id9ef50692819dcbebbd74a0aabffbfb3f39a4309

2015-02-06Re-arrange inter mode search order in RTC coding flowJingning Han
This commit makes the ZEROMV mode first in the search order to ensure that the zero mv is always checked in the RTC coding mode. It improves the average speed -6 compression performance by 0.3% in both PSNR and SSIM at no visible speed change. Change-Id: I465a7e59f4e20cd84fee3f02ced6f98036945949

The high bit depth build failed while building for 32bit target. The bugs were in vp9_highbd_subpel_variance.asm and vp9_highbd_sad4d_sse2.asm functions. This patch fixed the bugs, and made 32bit build work. Change-Id: Idc8e5e1b7965bb70d4afba140c6583c5d9666b75

2015-02-04Account for chroma component costs in RTC mode decisionJingning Han
This commit allows the encoder to account for additional chroma plane costs in the mode decision process, if the current block potentially contains significant color change. It improves the visual quality at very low bit-rates. The compression performance of dark720p is improved by 12.39% in speed 6. For jimred at 150 kbps, the PSNR of V component (red) increased by 0.2 dB, at the expense of about 5% increase in encoding time. Note that for sequences where the chroma components are fairly consistent, the encoding time increase is negligible. On average the rtc set compression performance is improved by 1.172% in PSNR and 1.920% in SSIM. Change-Id: Ia55b24ef23a25304f7ec9958fbf07fd6e658505c
2015-02-04vp9_dthread: remove frame_parallel_decoding_mode requirementYunqing Wang
This patch continues the work to remove frame_parallel_decoding_mode requirement in VP9 multi-threaded tile decoder. In order to do that, the frame counts associated to each thread need to be accumulated together after the frame is decoded. Change-Id: Idba1a756cedfed3c154aef52ed82c8da3bbf9e0c

2015-02-03Remove unnecessary pointer checkJohann
The original implementation had the following comment: // Ignore mv costing if mvsadcost is NULL However the current implementation does not allow for this. If x exists then nmvsadcost must not be null. This removes the only warning from -Wpointer-bool-conversion https://code.google.com/p/webm/issues/detail?id=894 Change-Id: I1a2cee340d7972d41e1bbbe1ec8dfbe917667085

2015-02-03vp9_dthread: pass frame counts to decoder functionsYunqing Wang
The current multi-threaded tile decoder requires that the videoes are encoded with frame_parallel_decoding_mode = 1. This requirement is not necessary, and is better to be removed. This patch includes the first part of the work. Change-Id: Ic7695fb3cfe13f9022582c9f0edd2aa6e2e36d28
