Log message:
Update to 1.0.0

* Bump BUILDLINK_ABI_DEPENDS to 1.0.0

Changelog:
2012-01-27 v1.0.0 "Duclair"
  Our fourth named release, focused on performance and features related to
  real-time encoding. It also fixes a decoder crash bug introduced in
  v0.9.7, so all users of that release are encouraged to upgrade.

  - Upgrading:
      This release is ABI incompatible with prior releases of libvpx, so the
      "major" version number has been bumped to 1. You must recompile your
      applications against the latest version of the libvpx headers. The
      API remains compatible, and this should not require code changes in most
      applications.

  - Enhancements:
      This release introduces several substantial new features to the encoder,
      of particular interest to real time streaming applications.

      Temporal scalability allows the encoder to produce a stream that can
      be decimated to different frame rates, with independent rate targetting
      for each substream.

      Multiframe quality enhancement postprocessing can make visual quality
      more consistent in the presence of frames that are substantially
      different quality than the surrounding frames, as in the temporal
      scalability case and in some forced keyframe scenarios.

      Multiple-resolution encoding support allows the encoding of the
      same content at different resolutions faster than encoding them
      separately.

  - Speed:
      Optimization targets for this release included the decoder and the real-
      time modes of the encoder. Decoder speed on x86 has improved 10.5% with
      this release. Encoder improvements followed a curve where speeds 1-3
      improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved
      1.5% to 10.5%, respectively. "Best" mode speed is consistent with the
      Cayuga release.

  - Quality:
      Encoder quality in the single stream case is consistent with the Cayuga
      release.

  - Bug Fixes:
      This release fixes an OOB read decoder crash bug present in v0.9.7
      related to the clamping of motion vectors in SPLITMV blocks. This
      behavior could be triggered by corrupt input or by starting
      decoding from a P-frame.

Log message:
Update to 0.9.7.1 (0.9.7 p1)

Changelog:
2011-08-15 v0.9.7-p1 "Cayuga" patch 1
  This is an incremental bugfix release against Cayuga. All users of that
  release are strongly encouraged to upgrade.

    - Fix potential OOB reads (cdae03a)

          An unbounded out of bounds read was discovered when the
          decoder was requested to perform error concealment (new in
          Cayuga) given a frame with corrupt partition sizes.

          A bounded out of bounds read was discovered affecting all
          versions of libvpx. Given an multipartition input frame that
          is truncated between the mode/mv partition and the first
          residiual paritition (in the block of partition offsets), up
          to 3 extra bytes could have been read from the source buffer.
          The code will not take any action regardless of the contents
          of these undefined bytes, as the truncated buffer is detected
          immediately following the read based on the calculated
          starting position of the coefficient partition.

    - Fix potential error concealment crash when the very first frame
      is missing or corrupt (a609be5)

    - Fix significant artifacts in error concealment (a4c2211, 99d870a)

    - Revert 1-pass CBR rate control changes (e961317)
      Further testing showed this change produced undesirable visual
      artifacts, rolling back for now.
