2018-09-03vp9-svc: Add bypass flag to constrain inter_layer.Marco Paniconi
The additional constraint imposed on inter-layer prediction should only be done for non-bypass (fixed) svc mode. Change-Id: Ia22cdb7bc21684776c9a13397e177a1e1c3d55a2
2018-09-02vp9-svc: Fix condition for pattern constraintsMarco Paniconi
For fixed/non-flexible SVC mode: on non-key spatial enhancement layers modify constraint on the inter-layer prediction to include the first_spatial_layer_to_encode. Change-Id: I6a59174976ad72d555653704dcd3b03c52e31b6f
2018-09-01Properly update the raw_src_frame for psnr calculationJingning Han
Update the raw_src_frame to be the current input source frame in the show_existing_frame mode. Change-Id: Ia8edf49ca948c45ffe6c60556756b36124ab092a
2018-08-31Build arf index stackJingning Han
Stack the ARF frame indexes. Use the most recent one as the ARF reference frame for frame coding. Change-Id: I88a2202fa5deb2587d861b434d27ab8de0642cf7
2018-08-31vp9-svc: Add first_spatial_layer_to_encode per superframeMarco Paniconi
VP9E_SET_SVC_LAYER_ID sets the first spatial layer to encoder per superframe, so add this parameter to svc encoder. This is needed, for example, to properly set is_key_frame for spatial layers when base spatial layer is skipped encoded. Change-Id: Ifd4ac77f539197ec021e62f4c624a6cc79d64f43
2018-08-31ML based rectangular partition search pruningHui Su
Add a ML model to predict if rectangular partition search can be skipped without much coding loss. This model is enabled for speed 0 low bitdepth only. Impact on coding performance is minor: avg_psnr ovr_psnr ssim lowres -0.005% 0.005% 0.017% midres 0.100% 0.114% 0.134% hdres 0.048% 0.083% 0.074% jvet480p 0.035% 0.027% 0.044% jvet720p 0.094% 0.090% 0.174% Tested encoding speed over 20 midres and hdres clips, average speed gain is about 8%; maximum speed gain is 23%.

2018-08-31Fix arf_src_offset calculationJingning Han
The offset should be computed with respect to the current coding process standing. Change-Id: I63fc303eb062d5fd68b8d1faa3b4172cdfcce168
2018-08-31Set minimum frame size to be 1 byteJingning Han
The show_existing_frame mode still needs to be sent to the decoder. Account for this as 1 byte. This would make the encoder properly update its state. Change-Id: I32a59ccb5d0e02cc6367c1a264b2de72dc1432a7

2018-08-28Skip unnecessary motion searchHui Su
If a ref frame is masked out, we do not need to do motion search for it. It makes speed 0 a little faster. Change-Id: I68f71255b2798b24fd1d5b28ed24a2ef87251413

2018-08-27Rework enc/dec mismatch detectionJingning Han
The previous enc/dec mismatch detection assumes the previously reconstructed frame would always stay at frame buffer pool index at 0. It could hence cause certain delay in enc/dec mismatch detection when the immediate reconstruction frame is not yet propagated to index 0 in the buffer map pool. This change always keeps the latest decoded show frame buffer index and directly gets the reconstructed frame from encoder and decoder buffer pools to check for mismatch.

2018-08-23Revert "Prevent double application of min rate in two pass."Hui Su
This reverts commit 416b7051d7f610ed6d62dff18af7776ec520fd9c. Reason for revert: it causes visual quality drop as described in b/112953058. Original change's description: > Prevent double application of min rate in two pass. > > The initial allocation of bits in the two pass code to each frame > should be within the min max limits on the command line. However, > when forming an ARF group the cost of the ARF is shared by frames > in that group such that the residual bits for a frame could drop below > the min value. This change prevents the minimum being re-applied > after the cost of the ARF has been deducted as this may otherwise > cause low rate sections to overshoot their target. > > Test runs comparing to a baseline run with min and max section pct > 0-2000% vs one closer to the YT use case (50-150%) suggest that > this fix not only results in better rate control but also gives a better > rd outcome. > > For example the HD set vs 0-2000% baseline (opsnr, ssim). > Old code (50-150): +0.751, +1.099 > New code(50-150): +0.241, -0.009 > > Change-Id: I715da7b130bf53ba8aa609532aa9e18b84f5e2ef TBR=yaowu@google.com,paulwilkins@google.com,debargha@google.com,builds@webmproject.org # Not skipping CQ checks because original CL landed > 1 day ago.

2018-08-22Sync prev_frame/last_show_frame update with decoderJingning Han

2018-08-22Skip update prev_mi frame in show_existing_frame modeJingning Han
When the current frame is coded by directly using a reference frame in buffer, no need to update the prev_mi frame information for next frame encoding control. Change-Id: I33fda8e70cdb31eb5b13b63e3dbd6e96ff85154d
2018-08-22Refactor encoder frame count updateJingning Han
This refactoring allows the encoder to skip frame count update in the show_existing_frame mode. Change-Id: Id69707976ccdad144cba93a8f5d36b6947611f91
2018-08-22Rework the ref_frame_skip_mask feature in RDOHui Su
Previously we often skip all compound inter prediction modes, causing large coding loss. This patch modifies how we set the ref_frame_skip_mask so that compound modes are considered in RDO. This affects speed>=1. Coding gains(overall psnr): lowres midres hdres average speed 1 0.54% 0.43% 0.64% 0.53% speed 2 0.59% 0.48% 0.60% 0.56% Tested encoding speed on 10 HD sequences, average speed loss is 5% for speed 1; 2% for speed 2.
