      A temporary fix on the RAM issue for upsampled referencing · c670e82f
      Zoe Liu authored
      When ext-refs is on, the encoding of HD videos, e.g. 1080p sequences
      will cause the failure to allocate up-sampled frame buffers. This CL
      temporarily turn off the use of upsampled references when ext-refs is
      on for any video resolution larger than 720 in either dimension. A
      more effective scheme for up-sampled referencing should be later
      considered.
      
      With the fix, the AWCY performance gains of ext-refs, vs baseline are:
      
      PSNR Y
      Average -2.55%
      1080p   -2.81%
      360p    -2.38%
      720p    -3.10%

      Properly release the memory space in encode_frame_to_data_rate() · f6214b96
      Jingning Han authored
      Explicitly release the locally allocated memory space in
      encode_frame_to_data_rate(). This resolves an memory space leak
      issue.

      Add ec_smallmul experiment. · b1c5760e
      Timothy B. Terriberry authored
      This reduces the multiplier width of daala_ec from 16x15->31 to
      8x15->23, which reduces hardware latency by an estimated 20% (and
      area for this module by an estimated 40%).
      
      These are the smallest logical changes required to achieve this,
      but the approach will be optimized significantly in subsequent
      commits.

      Avoid redundant tx_type search · 00491e0d
      Angie Chiang authored
      allow_txk_type doesn't contains all the logic of using pre
      assigned tx_type or doing the tx_type search.
      Here we use get_tx_type to avoid redundant tx_type search.

      pvq: Remove support for disabling nodesync. · 44bb6d06
      Timothy B. Terriberry authored
      This was broken by commit 1238137c.
      
      When calling the generic coder with a max, it truncates the CDF, but
      then tries to encode/decode with the Q15 entropy coder functions
      with built-in adaptation. That causes assertion failures, because the
      total probability isn't 32768.
      
      We could fix it by re-scaling the CDF, and then doing adaptation
      assuming there was no max, but that requires several special-case
      code paths.
      
      Instead, since non-robust streams were the only thing that still
      required calling the generic coder with a max, and since the gain
      from them is very small (and they require doing more DSP just to be
      able to parse the stream), we simply remove the option and force
      the use of robust streams all the time.
      
      With robust streams enabled, encoder output should not change, and
      all streams should remain decodable without decoder changes.
      
      Thanks to Nathan Egge for reporting the problem.
