      enabled 8x8 intra prediction modes on inter frames · a8fbab86
      Yaowu Xu authored
      This commit enabled the usage of 8x8 intra prediction modes on inter
      frames. There are a few TODO items related to this: 1)baseline entropy
      need be calibrated; 2)cost of UV need to be done more properly rather
      than using decision only relying on Y; 3)Threshold for allowing picking
      8x8 intra prediction should be lowered to lower than the B_PRED.
      
      Even with all the TODOs, tests showed consistent gain on derf set ~0.1%
      (PSNR:0.08% and SSIM:0.14%). It is assumed that 8x8 intra prediction
      will help more on large resolution clips, especially with above TODOs
      addressed.

      Segment Feature Data Access · a258bba1
      Paul Wilkins authored
      No change to functionality or output.
      
      Updates to the segment feature data structure now all done
      through functions such as set_segdata() and get_segdata()
      in seg_common.c.
      
      The reason for this is to make changing the structures (if needed)
      and debug easier.
      
      In addition it provides a single location for subsequent addition
      of range and validity checks. For  example valid combination of
      mode and reference frame.

      Further segment feature extensions. · 01ce04bc
      Paul Wilkins authored
      This quite large check in includes the following:
      
      Merge in some code from Ronald (mbgraph.c) that scans a Gf/arf group.
      This is used as a basis for a simple segmentation for the normal frames
      in a gf/arf group. This code also uses satd functions from Yaowu.
      
      Adds functionality for coding the latest possible position of an EOB for
      blocks in the segment. (Currently 0-15 only, hence just for 4x4 dct).
      Where the EOB position is 0 this acts like "skip" and the normal coding
      of skip at the per mb level is disabled.
      
      Added functions (seg_common.c) for setting and reading segment feature
      elements. These may want to be optimized away at some point but while the
      mecahnism is in a state of flux they provide a single location for making
      changes and keep things a bit cleaner.
      
      This is still proof of concept code. Currently the tested feature set:-
      
      Quantizer,
      Loop Filter level,
      Reference frame,
      Prediction Mode,
      EOB end stop.
      
      TBD:-
      
      Add functions for setting and reading the feature data with range
      and validity checking.
      
      Handling of signed and unsigned feature data. At the moment all is assumed
      to be signed and a sign bit is coded but many cannot be negative.
      
      Correct handling of EOB feature with intra coded blocks.
      
      Testing/trapping of legal/illegal ref frame and mode combinations.
      
      Transform size switch plus merge and test with 8c8 DCT work
      
      Merge and test with Sumans Segmenation coding optimizations

      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

      Increase static linkage, remove unused functions · 429dc676
      John Koleszar authored
      A large number of functions were defined with external linkage, even
      though they were only used from within one file. This patch changes
      their linkage to static and removes the vp8_ prefix from their names,
      which should make it more obvious to the reader that the function is
      contained within the current translation unit. Functions that were
      not referenced were removed.
      
      These symbols were identified by:
      
        $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \

      Eliminate more warnings. · 97b766a4
      Timothy B. Terriberry authored
      This eliminates a large set of warnings exposed by the Mozilla build
       system (Use of C++ comments in ISO C90 source, commas at the end of
       enum lists, a couple incomplete initializers, and signed/unsigned
       comparisons).
      It also eliminates many (but not all) of the warnings expose by newer
       GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
       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.

      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.
