av1_apply_encoding_flags() was called in encoder_encode(). If lag_in_frames > 0, it wouldn't be called for last several frames while flushing the encoder, and thus cpi->ref_frame_flags can not be set correctly. This patch fixed the issue by adding an extra flag cpi->ext_ref_frame_flags to store the external reference frame flag, and pass it to cpi->ref_frame_flags correctly.

Always assume ONE_SIDED_COMPOUND is true as it has been adopted officially. Further, this patch also fixes the cmake setup for the experiment of EXT_COMP_REFS, as when EXT_COMP_REFS is on, it shall always have ONE_SIDED_COMPOUND on (but that was not the case without this patch). We leave EXT_COMP_REFS for the time being, even though it is also adopted, since by keeping this flag, it may allow its turning off to tune the encoder speed. The experiment of EXT_COMP_REFS should be removed eventually at the closing of the bitstream. Change-Id: I0644318e522f5b48d5bba4e4391104a24d43cdc3

This reverts commit ab8bb8b8. The reverted breaks many nightly run tests, reverting this temporarily to allow nightly tests to detect other failures. Once the issues are fixed, we can reenable the change in the reverted commit. BUG=aomedia:1012 BUG=aomedia:1013 BUG=aomedia:1014 Change-Id: I2503fe78e47c7a08bb6cfdfff2c295cec0b6497d

A speedup feature that enforces the maximum number of reference frames to evaluate for each arbitrary frame to be 6, as opposed to the maximum syntax-allowed number of reference frames which is 7, through the following rules: (1) When all the possible reference frames are availble, we reduce the number of reference frames (7) by 1 by removing one reference frame; (2) Always retain GOLDEN_FARME/ALTEF_FRAME; (3) Check the earliest 2 remaining reference frames, and there are two options to remove one reference frame: (a) Remove the one with the lower quality factor; Otherwise if both frames have been coded at the same quality level, remove the earliest reference frame; (b) Always remove the earliest reference frame. Currently set option (a). This patch has demonstrated an encoder speedup of ~8.5%. It is under speed2 with "selective_ref_frame >= 2". (May be considered to move to speed1 later once the coding performance impact is evaluated further.) Using the following configure setups, the coding performance has been dropped on Google test sets (50 frames) in BDRate by ~0.2% for lowres and by ~0.1% for midres: --enable-experimental --disable-convolve-round --disable-ext-partition --disable-ext-partition-types --disable-txk-sel --disable-txm Change-Id: I84317bae00bfd90b2c3d301858a849f441974e6f

As of patch https://aomedia-review.googlesource.com/c/aom/+/28821 , loop-restoration units cannot cross tile borders. But the context around each processing unit was still allowed to cross tile borders. This is fine in the usual case - but, when loop filtering across tiles is switched off, we're supposed to be able to decode each tile completely independently (each tile column, if dependent-horztiles is on). Roughly, the change we need to make is: When loop filtering across tiles is switched off, we treat each tile as if it were a full frame, and extend the CDEF output for that tile to form a 3-pixel border around the tile. We only use deblocked above/below pixels for processing unit boundaries which lie inside a tile. In terms of the code, this is implemented in two parts. This only applies when the loop_filter_across_tiles_flag is false; otherwise, we keep the old behaviour. * For processing units at the top edge of a tile, fill the above context with copies of the topmost line of CDEF output *from the same tile*, rather than using deblocked pixels from the tile above. The below context of processing units at the bottom edge of a tile is treated analogously. * When setting up the boundary for a processing stripe at the left edge of a tile, fill the stripe's left boundary with copies of the leftmost column of CDEF output from the same tile. Again, processing stripes at the right edge of a tile are treated analogously. Similarly to the above/below boundaries, we store the overwritten pixels into a pair of left/right context buffers, and restore them to their original values once we've dealt with that processing stripe.

Remove the option of raw data or delta when coding the segment data, then only use delta coding. Raw data coding of segment data has been nowhere used but the option of "raw or delta codig of seg_data" has been coded to a bitstream. Change-Id: Iaf8f21692452d0c9a127b958812c6151d3c5db05

This change does not alter the bitstream. This change simplifies a subsequent commit to remove the custom DC_PRED used by CfL. To use the DC_PRED in AV1, CfL must consider the DC_PRED as a block instead of a single value.
