      Convert rc_max_intra_bitrate_pct to control · 1654ae9a
      John Koleszar authored
      Since this is the only ABI incompatible change since the last release,
      convert it to use the control interface instead. The member of the
      configuration struct is replaced with the VP8E_SET_MAX_INTRA_BITRATE_PCT
      control.
      
      More significant API changes were expected to be forthcoming when this
      control was first introduced, and while they continue to be expected,
      it's not worth breaking compatibility for only this change.

      vpxenc: prevent wraparound in the --rate-hist ringbuffer · 05239f0c
      John Koleszar authored
      For clips that are near 60fps and have a lot of alt refs, it's possible
      that the ring buffer holding the previous frames sizes/pts could wrap
      around, leading to a division by zero.
      
      In addition to checking for this condition in the ring buffer loop,
      the buffer size is made dependent on the actual frame rate in use,
      rather than defaulting to 60, which should improve accuracy at frame
      rates >= ~60.

      Adds "armvX-none-rvct" targets · 11a222f5
      Tero Rintaluoma authored
      Adds following targets to configure script to support RVCT compilation
      without operating system support (for Profiler or bare metal images).
       - armv5te-none-rvct
       - armv6-none-rvct
       - armv7-none-rvct
      
      To strip OS specific parts from the code "os_support"-config was added
      to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
      specific parts such as OS specific includes and function calls for
      timers and threads etc. This was done to enable RVCT compilation for
      profiling purposes or running the image on bare metal target with
      Lauterbach.
      
      Removed separate AREA directives for READONLY data in armv6 and neon
      assembly files to fix the RVCT compilation. Otherwise
      "ldr <reg>, =label" syntax would have been needed to prevent linker
      errors. This syntax is not supported by older gnu assemblers.

      CQ Mode · e0846c9c
      Paul Wilkins authored
      The merge includes hooks to for CQ mode and other code
      changes merged from the test branch.
      
      CQ mode attempts to maintain a more stable quantizer within a clip
      whilst also trying to adhere to a guidline maximum bitrate.
      
      The existing target data rate parameter is used to specify the
      guideline maximum bitrate.
      
      A new parameter allows the user to specify a target CQ level.
      
      For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the
      user specified value (0-63). However, in some cases the encoder may
      choose to impose a target CQ that is above that specified by the user,
      if it estimates that consistent use of the target value is not compatible
      with guideline maximum bitrate.

      Add psnr/ssim tuning option · b0da9b39
      John Koleszar authored
      Add a new encoder control, VP8E_SET_TUNING, to allow the application
      to inform the encoder that the material will benefit from certain
      tuning. Expose this control as the --tune option to vpxenc. The args
      helper is expanded to support enumerated arguments by name or value.
      
      Two tunings are provided by this patch, PSNR (default) and SSIM.
      Activity masking is made dependent on setting --tune=ssim, as the
      current implementation hurts speed (10%) and PSNR (2.7% avg,
      10% peak) too much for it to be a default yet.

      improve average framerate calculation · f7e187d3
      John Koleszar authored
      Change Ice204e86 identified a problem with bitrate undershoot due to
      low precision in the timestamps passed to the library. This patch
      takes a different approach by calculating the duration of this frame
      and passing it to the library, rather than using a fixed duration
      and letting the library average it out with higher precision
      timestamps. This part of the fix only applies to vpxenc.
      
      This patch also attempts to fix the problem for generic applications
      that may have made the same mistake vpxenc did. Instead of
      calculating this frame's duration by the difference of this frame's
      and the last frame's start time, we use the end times instead. This
      allows the framerate calculation to scavenge "unclaimed" time from
      the last frame. For instance:
      
        start |  end  | calculated duration

      The old value 1000 was too low, which caused the effective duration and
      frame rate calculation to have an 1% error for typical 30 frame/second

      undershooting target bit rate by 1% or so for 30 fps input.
