      Fix necessary for input partitions iface to match the RTP profile · e529a825
      Stefan Holmer authored
      These changes fixes a glitch between the RTP profile and the input
      partitions interface. Since there's no way for the user to know the
      actual number of partitions, the decoder have to read the
      multi_token_paritition bits also when input partitions mode is
      enabled.
      
      Included are also a couple of fixes for issues with independent
      partitions and uninitialized memory reads.

      Modified original patch If2f07220885c4c3a0cae0dace34ea0e36124f001
      according to comments. Scheduled code a little bit to prevent some
      interlocks.

      enable selecting&transmitting to for intra mode entropy · 1d44e7ce
      Yaowu Xu authored
      This commit added a 3 bit index to the bitstream, the index is used to
      look into the intra mode coding entropy context table. The commit uses
      the mode stats to calculate the cost of transmitting modes using 8
      possible entropy distributions, and selects the distribution that
      provides the lowest cost to do the actual mode coding.
      
      Initial test show this provides additional .2%~.3% gain over quantizer
      adaptive intra mode coding. So the adaptive intra mode coding provides
      a total of .5%(psnr) to .6% gain(ssim) combined for all-key-encoding
      
      To build and test, configure with
      --enable-experimental --enable-qimode

      add 8x8 intra prediction modes · ca6b85aa
      Yaowu Xu authored
      Patch 1 to Patch 3 is an initial implementation of 8x8 intra prediction
      modes, here are with the following assumptions:
      a. 8x8 has 4 prediction modes DC, H, V and TM
      b. UV 4x4 block use the same mode as corresponding 8x8 area
      c. i8x8 modes are enabled for key frame only for now
      Patch 4:
      d. removed debug code from previous patches
      Patch 5:
      e. added stats code to collect entropy stats and further cleaned up
      Patch 6:
      f. changed mode stats code to collect finer stats of modes
      Patch 7:
      g. normalized i8x8 modes distribution to total at 256 (8bits).
      Patch 8:
      h. fixed a bug in decoder and removed debug printf output.
      Patch 9:
      i. more cleanups to address paul's comment
      Patch 10:
      j. messy rebase/merges to bring the commit up to date.
      
      Tests on HD clips encoded with all key frame showing consistent gain
      on all clips and all metrics:~0.5%(psnr) and 0.6%(ssim):

      Code all the features for one segment (grouped together)
      then all for the next etc. etc. rather than grouping the
      data by feature.

      Change to segment_feature_data[][] structure. · 1c24442a
      Paul Wilkins authored
      This data structure is  now [Segment ID][Features]
      rather than [Features][Segment_ID]
      
      I propose as a separate modification to make the experimental
      bit stream reflect this such that all the features for a segment
      are coded together.
