      Bitstream debug tool · 4de81ee1
      Angie Chiang authored
      This is a debug tool used to detect bitstream error. On encoder side, it pushes
      each bit and probability into a queue before the bit is written into the
      Arithmetic coder. On decoder side, whenever a bit is read out from the
      Arithmetic coder, it pops up the reference bit and probability from the queue as
      well. If the two results do not match, this debug tool will report an error.
      This tool can be used to pin down the bitstream error precisely. By combining
      gdb's backtrace method, we can detect which module causes the bitstream error.

      Fix a bug in RATE_FACTOR_LEVEL definition for ext-refs · cdd4eb02
      Zoe Liu authored
      There was a bug in the original set up for RATE_FACTOR_LEVELS, which
      results that rate_factor_deltas for GF_ARF_STD is 2.00, instead of the
      intentional value of 1.75, whereas for KF_STD is 0.00, instead of the
      intentional value of 2.00.
      Nevertheless, if simply fixing the bug as in the first patch, the RD
      performance unexpectedly dropped by 0.143% in Avg bitrate using
      Overall PSNR, especially for following sequences in lowres:
      bridge_close_cif: dropped by 1.468%
      container_cif: dropped by 2.140%
      husky_cif: dropped by 0.826%
      motherdaughter_cif: dropped by 0.798%
      rasehorses_240p: dropped by 0.805%
      students_cif: dropped by 1.411%
      This indicates that we should boost up the value for GF_ARF_STD from
      1.75 to at least to 2.00. After doing so, while still keeps 2.00 for
      KF_STD, the new patch achieves a small gain of 0.15% for the baseline,
      and a smaller gain of 0.06% for the experiment of ext-refs. Most
      sequences keep the similar RD performance in lowres, except for the
      following ones that obtain a bigger gain:
      (1) Baseline:
      container_cif: 1.628%
      students_cif: 1.015%
      (2) ext-refs
      tennis_sif: 1.248%

      Add interface to compute gm parameters in encodeframe · d616a5ce
      Sarah Parker authored
      This patch just creates the interface for global motion computation
      and calls it from encodeframe. Currently, the function
      compute_global_motion_feature_based is empty and the work to do
      the actual parameter calculation will be added in a future patch.
