      Modified frame buffer handling · f68aaa38
      Adrian Grange authored
      This patch is the first step toward simplifying the
      frame buffer handling.
      The final goal is to have a common frame buffer handling
      framework for both encoder and decoder that incorporates
      the existing ability to use externally allocated memory.

      allow config options to limit max size of decode · 943e4327
      Jim Bankoski authored
      This is a practical concern to allow us to fail in a decoder instance
      if the size of a file is bigger than we can reasonably handle.

      Changes to rd balance and multi-arf bug fix. · b691230d
      Paul Wilkins authored
      2 pass only change to calculation of rd mult based on Q.
      Make a small adjustment based on frame type and also
      replace adjustment based on iifactor with an one based
      on the ambient GF/ARF boost level.
      Also fix multi arf bug / issue.
      Overall these change give an slight improvement in ssim
      but hurt psnr a little.

      [spatial svc]Implement alt reference frames · e899859c
      Minghai Shang authored
      All changes are for spatial svc only.
      1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
      2. Use golden reference idx for spatial reference
      3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
      4. Add "auto-alt-refs" in svc options

          thread: remove harmless race on status_ in End()
          if a thread was still doing work when End() was called there'd be a race
          on worker->status_. in these cases, however, the specific value is
          meaningless as it would be >= OK and the thread would have been shut
          down properly, but we'll check 'impl_' instead to avoid any potential
          TSan/DRD reports.

      Re-design quantization process for 32x32 transform block · 9ad1b9fc
      Jingning Han authored
      This commit enables a new quantization process for 32x32 2D-DCT
      transform coefficient blocks. It improves the compression
      performance of speed 5 by 1.4%. The overall compression gains of
      speed 5 due to the new quantization scheme is 4.7%. It also includes
      the SSSE3 implementation of the 32x32 quantization process.

      Fix decoder handling of intra-only frames · 7c43fb67
      Adrian Grange authored
      This patch fixes bug 633:
      The first decoded frame does not have to be a keyframe,
      it could be an inter-frame that is coded intra-only.
      This patch fixes the handling of intra-only frames.
      A test vector has also been added that encodes 3
      intra-only frames at the start of the clip. The
      test vector was generated using the code in the
      following patch:

      In the previous version, only certain buffers in the macroblockd were saved and

      code was then rolled into a loop for readability.
      Also contains a tiny fix for when the -DOUTPUT_YUV_DENOISED flag is used.
