      Change return type of tell and tell_frac to uint32_t. · b244f396
      Nathan E. Egge authored
      The bit accounting functions aom_reader_tell() and aom_reader_tell_frac()
       return the number of bits and 1/8th bits respectively.
      This patch changes the return type from ptrdiff_t which is signed to
       uint32_t which is unsigned.
      The size_t type is not used since we only care about the number of bits
       or 1/8 bits per entropy coder context and we don't expect to code more
       than 512 megabits per tile.

      Bit accounting. · 6048d052
      Michael Bebenita authored
      This patch adds bit account infrastructure to the bit reader API.
      When configured with --enable-accounting, every bit reader API
      function records the number of bits necessary to decoding a symbol.
      Accounting symbol entries are collected in global accounting data
      structure, that can be used to understand exactly where bits are
      spent (http://aomanalyzer.org). The data structure is cleared and
      reused each frame to reduce memory usage. When configured without
      --enable-accounting, bit accounting does not incur any runtime
      overhead.
      
      All aom_read_xxx functions now have an additional string parameter
      that specifies the symbol name. By default, the ACCT_STR macro is
      used (which expands to __func__). For more precise accounting,
      these should be replaced with more descriptive names.

      Refactor bitreader and bitwriter wrapper. · e691a24c
      Nathan E. Egge authored
      Move code for reading and writing literals and reading trees to use
      just the aom_read_bit() and aom_write_bit() function calls.

      Bitstream debug tool · 4de81ee1
      Angie Chiang authored
      This is a debug tool used to detect bitstream error. On encoder side, it pushes
      each bit and probability into a queue before the bit is written into the
      Arithmetic coder. On decoder side, whenever a bit is read out from the
      Arithmetic coder, it pops up the reference bit and probability from the queue as
      well. If the two results do not match, this debug tool will report an error.
      This tool can be used to pin down the bitstream error precisely. By combining
      gdb's backtrace method, we can detect which module causes the bitstream error.
