      Fix generic-gnu target build · 93a8a1eb
      Adrian Grange authored
      Added macro to conditionally compile some of the
      post-processing functions only when CONFIG_POSTPROC
      is defined.
      This was causing the build for the generic-gnu target
      to fail.

      Fix rounding in ARNR calculation · 928b34e8
      Adrian Grange authored
      The rounding of the ARNR filter output prior to
      normalization by the filter strength was incorrect
      when strength = 0.
      In this case 1 << (strength - 1) would not create the
      required rounding of 0, rather it would outrange. This
      patch fixes this issue.

      Remove VP8 save_reg_neon function · 096eaba7
      Yunqing Wang authored
      This patch did a cleanup following the commit "Save NEON registers
      in VP8 NEON functions". The pushing/poping of callee-saved NEON
      registers was moved into individual NEON functions. Therefore,
      we don't need to save those registers at the beginning of codec.
      The related code was removed.

      Save NEON registers in VP8 NEON functions · 33df6d1f
      Yunqing Wang authored
      The recent compiler can generate optimized code that uses NEON registers
      for various operations besides floating-point operations. Therefore,
      only saving callee-saved registers d8 - d15 at the beginning of the
      encoder/decoder is not enough anymore. This patch added register saving
      code in VP8 NEON functions that use those registers.

      Prevent reading of uninitialized value · 99230aeb
      Yaowu Xu authored
      This commit added a check of reference frame to make sure that pre
      buffer pointers are initialized only when necessary and make them
      to 0 if ref frame is intra, hence those buffer should never be used.

      Enable vpxenc to specify internal coded frame size · f7bd1274
      Adrian Grange authored
      Added command line flags "resize-width" & "resize-height"
      to allow the user to specify the frame size to encode at.
      These two flags are ignored if the "resize-allowed" switch
      is not set to 1.
      All frames in the clip are then encoded at this size, which
      must be smaller than the raw frame size.
