      Use MAX_ENTROPY_TOKENS and ENTROPY_NODES more consistently · b32da7c3
      John Koleszar authored
      There were many instances in the code of vp8_coef_tokens and
      vp8_coef_tokens-1, which was a preprocessor macro despite the naming
      convention. Replace these with MAX_ENTROPY_TOKENS and ENTROPY_NODES,
      respectively.

      New ways of passing encoded data between encoder and decoder. · 7296b3f9
      Stefan Holmer authored
      With this commit frames can be received partition-by-partition
      from the encoder and passed partition-by-partition to the
      decoder.
      
      At the encoder-side this makes it easier to split encoded
      frames at partition boundaries, useful when packetizing
      frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled,
      several VPX_CODEC_CX_FRAME_PKT packets will be returned
      from vpx_codec_get_cx_data(), containing one partition
      each. The partition_id (starting at 0) specifies the decoding
      order of the partitions. All partitions but the last has
      the VPX_FRAME_IS_FRAGMENT flag set.
      
      At the decoder this opens up the possibility of decoding partition
      N even though partition N-1 was lost (given that independent
      partitioning has been enabled in the encoder) if more info
      about the missing parts of the stream is available through
      external signaling.
      
      Each partition is passed to the decoder through the
      vpx_codec_decode() function, with the data pointer pointing
      to the start of the partition, and with data_sz equal to the
      size of the partition. Missing partitions can be signaled to
      the decoder by setting data != NULL and data_sz = 0. When
      all partitions have been given to the decoder "end of data"
      should be signaled by calling vpx_codec_decode() with
      data = NULL and data_sz = 0.
      
      The first partition is the first partition according to the
      VP8 bitstream + the uncompressed data chunk + DCT address
      offsets if multiple residual partitions are used.

      Stefan Holmer authored
      Adding capabilities with which the encoder can output frames
      partition by partition, and the decoder can get input data
      partition by partition.

      Adding support for independent partitions · 4cb0ebe5
      Stefan Holmer authored
      Adding support in the encoder for generating
      independent residual partitions by forcing
      equal probabilities over the prev coef entropy
      contexts.

      Avoid text relocations in ARM vp8 decoder · e3f850ee
      Mike Hommey authored
      The current code stores pointers to coefficient tables and loads them to
      access the tables contents. As these pointers are stored in the code
      sections, it means we end up with text relocations. eu-findtextrel will
      thus complain about code not compiled with -fpic/-fPIC.
      
      Since the pointers are stored in the code sections, we can actually cheat
      and let the assembler generate relative addressing when accessing the
      coefficient tables, and just load their location with adr.

      adjusting the calculation of errorperbit · 10ed60dc
      Yaowu Xu authored
      RDMULT/RDDIV defines a bit worth of distortion in term of sum squared
      difference. This has also been used as errorperbit in subpixel motion
      search, where the distortions computed as variance of the difference.
      The variance of differences is different from sum squared differences
      by amount of DC squared. Typically, for inter predicted MBs, this
      difference averages around 10% between the two distortion, so this patch
      introduces a 110% constant in deriving errorperbit from RDMULT/RDDIV.
      
      Test on CIF set shows small but positive gain on overall PSNR (.03%)
      and SSIM (.07%), overall impact on average PSNR is 0.

      Improved vp8dx_decode_bool · 67a1f98c
      Scott LaVarnway authored
      Relocated the vp8dx_bool_decoder_fill() call, allowing
      the compiler to produce better assembly code.  Tests
      showed a 1 - 2 % performance boost (x86 using gcc)
      for the 720p clip used.

      gen_msvs_proj: write boolean for Debug attribute · 91b16720
      James Zern authored
      Replace =1 with =true for yasm tool element. This aids in upgrading
      e.g., vs9 project files to vs10.
      build/x86-msvs/yasm.xml generated during conversion will require the
      Separator attribute to be removed for the build to complete
      successfully.
