      This data structure is  now [Segment ID][Features]

      I propose as a separate modification to make the experimental

      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.

      MODE_INFO size reduction · e11f21af
      Scott LaVarnway authored
      Declared the bmi in MODE_INFO as a union instead of B_MODE_INFO.
      This reduced the memory footprint by 518,400 bytes for 1080
      resolutions.  The decoder performance improved by ~4% for the
      clip used and the encoder showed very small improvements. (0.5%)
      This reduction was first mentioned to me by John K. and in a
      later discussion by Yaowu.
      This is WIP.

      A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output
      from the function is non-zero if the last decoded frame contains

      The decoder is also modified to accept encoded frames of zero length.
      A zero length frame indicates to the decoder that one or more frames
      have been completely lost. This will mark the last decoded reference
      buffer as corrupted. The data pointer can be NULL if the length is
      zero.

      Use of temporal context for encoding delta updates. · b9a18344
      Suman Sunkara authored
      - Used three probability approach for temporal context as follows:
      P0 - probability of no change if both above and left not changed
      P1 - probability of no change if one of above and left has changed
      P2 - probability of no change if both above and left have changed
      
      In addition, a 1 bit/frame has been used to decide whether to use temporal context or to encode directly.  The cost of using both the schemes is calculated ahead and the temporal_update flag is set if the cost of using temporal context is lower than encoding the segment ids directly.
      
      This approach has given around 20% reduction in cost of bits needed to encode segmentation ids.

      This is true, so far as it goes, but it's comparing against an enum,
       and the C standard does not mandate that enums be unsigned, so the
       checks can't be removed.

       without checking the return values).
      There are a few spurious warnings left on my system:
      
      ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
       uninitialized in this function
      gcc seems to be unable to figure out that the value shortcut doesn't
       change between the two if blocks that test it here.
      
      ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
       expression >= 0 is always true
      ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
       expression >= 0 is always true
      This is true, so far as it goes, but it's comparing against an enum, and the C
       standard does not mandate that enums be unsigned, so the checks can't be
       removed.

      Improve handling of invalid frames. · 09bcc1f7
      Timothy B. Terriberry authored
      The code was not checking for frame sizes smaller than 3 bytes, and the
       partition size checks might have failed if the input buffer was within
       16MB of the top of the heap.
      In addition, the reference count on the current frame buffer was not
       being decremented on error, so after a small number of errors, no new
       frame buffer could be found and it would run off the list of them.
