-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.
-
-
-2011-08-02 v0.9.7 "Cayuga"
-  Our third named release, focused on a faster, higher quality, encoder.
-
-  - Upgrading:
-    This release is backwards compatible with Aylesbury (v0.9.5) and
-    Bali (v0.9.6). Users of older releases should refer to the Upgrading
-    notes in this document for that release.
-
-  - Enhancements:
-          Stereo 3D format support for vpxenc
-          Runtime detection of available processor cores.
-          Allow specifying --end-usage by enum name
-          vpxdec: test for frame corruption
-          vpxenc: add quantizer histogram display
-          vpxenc: add rate histogram display
-          Set VPX_FRAME_IS_DROPPABLE
-          update configure for ios sdk 4.3
-          Avoid text relocations in ARM vp8 decoder
-          Generate a vpx.pc file for pkg-config.
-          New ways of passing encoded data between encoder and decoder.
-
-  - Speed:
-      This release includes across-the-board speed improvements to the
-      encoder. On x86, these measure at approximately 11.5% in Best mode,
-      21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6).
-      On ARM Cortex A9 with Neon extensions, real-time encoding of video
-      telephony content is 35% faster than Bali on single core and 48%
-      faster on multi-core. On the NVidia Tegra2 platform, real time
-      encoding is 40% faster than Bali.
-
-      Decoder speed was not a priority for this release, but improved
-      approximately 8.4% on x86.
-
-          Reduce motion vector search on alt-ref frame.
-          Encoder loopfilter running in its own thread
-          Reworked loopfilter to precalculate more parameters
-          SSE2/SSSE3 optimizations for build_predictors_mbuv{,_s}().
-          Make hor UV predict ~2x faster (73 vs 132 cycles) using SSSE3.
-          Removed redundant checks
-          Reduced structure sizes
-          utilize preload in ARMv6 MC/LPF/Copy routines
-          ARM optimized quantization, dfct, variance, subtract
-          Increase chrow row alignment to 16 bytes.
-          disable trellis optimization for first pass
-          Write SSSE3 sub-pixel filter function
-          Improve SSE2 half-pixel filter funtions
-          Add vp8_sub_pixel_variance16x8_ssse3 function
-          Reduce unnecessary distortion computation
-          Use diamond search to replace full search
-          Preload reference area in sub-pixel motion search (real-time mode)
-
-  - Quality:
-      This release focused primarily on one-pass use cases, including
-      video conferencing. Low latency data rate control was significantly
-      improved, improving streamability over bandwidth constrained links.
-      Added support for error concealment, allowing frames to maintain
-      visual quality in the presence of substantial packet loss.
-
-          Add rc_max_intra_bitrate_pct control
-          Limit size of initial keyframe in one-pass.
-          Improve framerate adaptation
-          Improved 1-pass CBR rate control
-          Improved KF insertion after fades to still.
-          Improved key frame detection.
-          Improved activity masking (lower PSNR impact for same SSIM boost)
-          Improved interaction between GF and ARFs
-          Adding error-concealment to the decoder.
-          Adding support for independent partitions
-          Adjusted rate-distortion constants
-
-
-  - Bug Fixes:
-          Removed firstpass motion map
-          Fix parallel make install
-          Fix multithreaded encoding for 1 MB wide frame
-          Fixed iwalsh_neon build problems with RVDS4.1
-          Fix semaphore emulation, spin-wait intrinsics on Windows
-          Fix build with xcode4 and simplify GLOBAL.
-          Mark ARM asm objects as allowing a non-executable stack.
-          Fix vpxenc encoding incorrect webm file header on big endian
-
-
 2011-03-07 v0.9.6 "Bali"
   Our second named release, focused on a faster, higher quality, encoder.

-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ USAGE
-
-
-Dropping A Range Of Frames
---------------------------
-To drop a range of frames, specify the starting frame and the ending
-frame to drop, separated by a dash. The following command will drop
-frames 5 through 10 (base 1).
-
-  $ ./decode_with_partial_drops in.ivf out.i420 5-10
-
-
-Dropping A Pattern Of Frames
-----------------------------
-To drop a pattern of frames, specify the number of frames to drop and
-the number of frames after which to repeat the pattern, separated by
-a forward-slash. The following command will drop 3 of 7 frames.
-Specifically, it will decode 4 frames, then drop 3 frames, and then
-repeat.
-
-  $ ./decode_with_partial_drops in.ivf out.i420 3/7
-
-Dropping Random Parts Of Frames
--------------------------------
-A third argument tuple is available to split the frame into 1500 bytes pieces
-and randomly drop pieces rather than frames. The frame will be split at
-partition boundaries where possible. The following example will seed the RNG
-with the seed 123 and drop approximately 5% of the pieces. Pieces which
-are depending on an already dropped piece will also be dropped.
-
-  $ ./decode_with_partial_drops in.ivf out.i420 5,123
-
-
-Extra Variables
----------------
-This example maintains the pattern passed on the command line in the
-`n`, `m`, and `is_range` variables:
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ EXTRA_VARS
-int              n, m, mode;
-unsigned int     seed;
-int              thrown=0, kept=0;
-int              thrown_frame=0, kept_frame=0;
-vpx_codec_dec_cfg_t  dec_cfg = {0};
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ EXTRA_VARS
-
-
-Making The Drop Decision
-------------------------
-The example decides whether to drop the frame based on the current
-frame number, immediately before decoding the frame.
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PRE_DECODE
-/* Decide whether to throw parts of the frame or the whole frame
-   depending on the drop mode */
-thrown_frame = 0;
-kept_frame = 0;
-switch (mode)
-{
-case 0:
-    if (m - (frame_cnt-1)%m <= n)
-    {
-        frame_sz = 0;
-    }
-    break;
-case 1:
-    if (frame_cnt >= n && frame_cnt <= m)
-    {
-        frame_sz = 0;
-    }
-    break;
-case 2:
-    throw_packets(frame, &frame_sz, n, &thrown_frame, &kept_frame);
-    break;
-default: break;
-}
-if (mode < 2)
-{
-    if (frame_sz == 0)
-    {
-        putc('X', stdout);
-        thrown_frame++;
-    }
-    else
-    {
-        putc('.', stdout);
-        kept_frame++;
-    }
-}
-thrown += thrown_frame;
-kept += kept_frame;
