      Fix corrupt arf groups due to low "lag_in_frames" · 48110d0f
      paulwilkins authored
      Having a very small value for "lag_in_frames" can result in
      corrupt arf groups including displayed frames that update
      the arf buffer and fake overlay frames that are not in fact
      overlays of real arfs but are nevertheless starved of bits.
      Leaving lag_in_frames at the default of 25 for these 5 frame two
      pass VBR tests should now give rise to a valid ARF coding pattern
      as follows:-  K(ey), A(rf), N(ormal), N, N, O(verlay).
      This change is part of a response to BUG=webm:1454 where broken
      arf groups interacted badly with a change that corrects for large rate
      misses. However, it may still in some cases increase encode time by
      virtue of the fact that the unit test now codes a correct coding pattern
      with "hidden" ARF frames.

      Force the bit exactness in the first pass · bfd0f41f
      Yunqing Wang authored
      Originally, for the purpose of keeping a fast first pass, the first-pass
      stats between row_mt_mode = 0 and row_mt_mode = 1 are not bit exact, but
      that difference is very small that doesn't cause a mismatch between the
      final bitstreams. However, if the encoder changes, this minor difference
      may cause a mismatch. Thus, this patch always forces the first pass to
      be bit exact.

      Make the row based multi-threaded encoder deterministic · 10a497bd
      Yunqing Wang authored
      This patch followed allow_exhaustive_searches feature modification and
      continued to modify the encoder to achieve the determinism in the row
      based multi-threaded encoding. While row-mt = 1 and using multiple
      threads, the adaptive feature in encoder was disabled, which gave
      BDRate gain(at speed 1, -0.6% ~ -0.7%; at speed 2, -0.46% ~ -0.59%),
      but some encoder speed losses(7% ~ 10% at speed 1 and 3% ~ 6% at
      speed 2). These speed losses were acceptable considering the speed
      gains obtained from row-mt.

      Improve VP9 encoder threading test for better coverage · cc168054

      Re-organized the encoder threading tests and grouped tests into
      4 parts. Added PSNR checking test to make sure the PSNR variation
      is within a small range.

      The bitstream bit match test in multi-threaded encoder · 318ca076
      Yunqing Wang authored
      While the new-mt mode is enabled(namely, allowing to use row-based
      multi-threading in encoder), several speed features that adaptively
      adjust encoding parameters during encoding would cause mismatch
      between single-thread encoded bitstream and multi-thread encoded
      bitstream. This patch provides a set_control API to disable these
      features, so that the bit match bitstream is obtained in the unit

      Add the multi-threaded first pass encoder unit test · b0d8a75e
      Yunqing Wang authored
      Added the multi-threaded first pass encoder unit test in VP9. The test is
      to check if the new multi-threaded first pass encoder(namely, new-mt = 1)
      still generates matching stats. In the unit test, the new-mt mode will be
      turned on once the multi-threaded first pass implementation is checked in.

      vp9-tests : split VpxEncoderThreadTest into two tests. · 719f39f4
      Jim Bankoski authored
      VpxEncoderThreadTest was taking a very long time for some runs and
      timing out a lot.   This is an attempt to split the test into runs
      that can be run nightly ( speeds 2 through 9) and runs that can
      be run weekly ( speeds 0-1 ).

      Modify the encoder multi-thread unit test · c327b3f0
      Yunqing Wang authored
      Modified the encoder multi-thread test so that it included cpu-used=0 and
      frame_parallel_decoding_mode is 1 by default, which disables probability
      updating and gives lower encoding quality. Current VP9 multi-threading
      encoder and decoder support probability updating. To test this part, we
      should turn on it in the unit test, namely, setting frame-parallel to 0.

      vp9_bitstream: Encode tiles in parallel · 5deffa11
      Vignesh Venkatasubramanian authored
      Re-use the tile worker threads to pack the bitstream in parallel
      on a per-tile basis.  Restricting this to real-time only for now
      (further testing is needed to ensure this does not make 2-pass
      worse in any case).

      Yunqing Wang authored
      The unit tests for VP9 multi-threaded encoder are added, which
      carry out tests for all three modes(i.e. kTwoPassGood, kOnePassGood
      and kRealTime), and speeds ranging from 1 to 8. A 1280x720 test
      clip is used, which is encoded into multiple tiles. The number of
      threads is num_of_tiles.
