      Change the encryption feature to use a callback for decryption. · 368c7237
      Jeff Petkau authored
      This allows code calling the library can choose an arbitrary
      encryption algorithm.
      
      Decoder control parameter VP8_SET_DECRYPT_KEY is renamed to
      VP8D_SET_DECRYPTOR, and now takes an small config struct instead
      of just a byte array.

      Differential encoding of probability updates · c6f1bf43
      Deb Mukherjee authored
      Adds differential encoding of prob updates using a subexponential
      code centered around the previous probability value.
      Also searches for the most cost-effective update, and breaks
      up the coefficient updates into smaller groups.

      Moved vp8_encode_bool into boolhuff.h · a25f6a9c
      Scott LaVarnway authored
      allowing the compiler to inline this function.  For real-time
      encodes, this gave a boost of 1% to 2.5%, depending on the
      speed setting.

      Changed above and left context data layout · e85e6315
      Scott LaVarnway authored
      The main reason for the change was to reduce cycles in the token
      decoder. (~1.5% gain for 32 bit)  This layout should be more
      cache friendly.
      
      As a result of this change, the encoder had to be updated.

      Change bitreader to use a larger window. · c17b62e1
      Timothy B. Terriberry authored
      Change bitreading functions to use a larger window which is refilled less
       often.
      
      This makes it cheap enough to do bounds checking each time the window is
       refilled, which avoids the need to copy the input into a large circular
       buffer.
      This uses less memory and speeds up the total decode time by 1.6% on an ARM11,
       2.8% on a Cortex A8, and 2.2% on x86-32, but less than 1% on x86-64.
      
      Inlining vp8dx_bool_decoder_fill() has a big penalty on x86-32, as does moving
       the refill loop to the front of vp8dx_decode_bool().
      However, having the refill loop between computation of the split values and
       the branch in vp8_decode_mb_tokens() is a big win on ARM (presumably due to
       memory latency and code size: refilling after normalization duplicates the
       code in the DECODE_AND_BRANCH_IF_ZERO and DECODE_AND_LOOP_IF_ZERO cases.
      Unfortunately, refilling at the end of vp8dx_bool_decoder_fill() and at the
       beginning of each decode step in vp8_decode_mb_tokens() means the latter
       requires an extra refill at the end.
      Platform-specific versions could avoid the problem, but would require most of
       detokenize.c to be duplicated.
