      Fix inter_zz_count calculation bug · 8ee88da0
      Yunqing Wang authored
      The current way of counting inter_zz_count doesn't work correctly
      in multi-threaded encoding. Calculating it after the frame is
      encoded fixed the problem.

      Optimizes updates of encoder block ptrs · e66e9ddf
      Attila Nagy authored
      Precalculated block ptrs do not need updates during encoding.
      Set these at init stage.
      
      Moved the allocation of 'mt_current_mb_col' (last encoded MB on each
      row) to vp8_alloc_compressor_data(), so that it is correctly
      reallocated when frame size is changing.

      Fix segmentation updates with vp8_set_roimap() · 7c32cb52
      Paul Wilkins authored
      Changes relating to Issue 411
      
      Removed code that was clearing down the segmentation data each
      frame.
      
      Added range/parameter checking in vp8_set_roimap(); Return error
      if called when cyclic_refresh is enabled.
      
      Correct setup_features() so that it sets or clears the segment update
      flags as appropriate.

      Packing bitstream on-the-fly with delayed context updates · 52cf4dca
      Attila Nagy authored
      Produce the token partitions on-the-fly, while processing each MB.
      Context is updated at the beginning of each frame based on the
      previoud frame's counters. Optimally encoder outputs partitions in
      separate buffers. For frame based output, partitions are concatenated
      internally.
      
      Limitations:
          - enabled just in combination with realtime-only mode
          - number of encoding threads has to be equal or less than the
          number of token partitions. For this reason, by default the encoder
          will do 8 token partitions.
          - vpxenc supports partition output (-P) just in combination with
          IVF output format (--ivf)
      
      Performance:
          - Realtime encoder can be up to 13% faster (ARM) depending on the number
          of threads and bitrate settings. Constant gain over the 5-16 speed
          range.
          - Token buffer reduced from one frame to 8 MBs
      
      Quality:
          - quality is affected by the delayed context updates. This again
          dependents on input material, speed and bitrate settings. For VC
          style input the loss seen is up to 0.2dB. If error-resilient=2
          mode is used than the effect of this change is negligible.
      
      Example:
      ./configure --enable-realtime-only --enable-onthefly-bitpacking
      ./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480
      --target-bitrate=1000 --token-parts=3 --static-thresh=2000
      --ivf -P -t 4 -o strm.ivf tanya_640x480.yuv

      Update encoder mb_skip_coeff and prob_skip_false calculation · ce42e79a
      Attila Nagy authored
      mode_info_context->mbmi.mb_skip_coeff has to always reflect the
      existence or not of coeffs for a certain MB. The loopfilter needs this
      info.
      mb_skip_coeff is either set by the vp8_tokenize_mb or has to be set to
      1 when the MB is skipped by mode selection. This has to be done
      regardless of the mb_no_coeff_skip value.
      
      prob_skip_false is needed just when mb_no_coeff_skip is 1. No need to
      keep count of both skip_false and skip_true as they are complementary
      (skip_true+skip_false = total_mbs)

      New RTCD implementation · a910049a
      John Koleszar authored
      This is a proof of concept RTCD implementation to replace the current
      system of nested includes, prototypes, INVOKE macros, etc. Currently
      only the decoder specific functions are implemented in the new system.
      Additional functions will be added in subsequent commits.
      
      Overview:
        RTCD "functions" are implemented as either a global function pointer
        or a macro (when only one eligible specialization available).
        Functions which have RTCD specializations are listed using a simple
        DSL identifying the function's base name, its prototype, and the
        architecture extensions that specializations are available for.
      
      Advantages over the old system:
        - No INVOKE macros. A call to an RTCD function looks like an ordinary
          function call.
        - No need to pass vtables around.
        - If there is only one eligible function to call, the function is
          called directly, rather than indirecting through a function pointer.
        - Supports the notion of "required" extensions, so in combination with
          the above, on x86_64 if the best function available is sse2 or lower
          it will be called directly, since all x86_64 platforms implement
          sse2.
        - Elides all references to functions which will never be called, which
          could reduce binary size. For example if sse2 is required and there
          are both mmx and sse2 implementations of a certain function, the
          code will have no link time references to the mmx code.
        - Significantly easier to add a new function, just one file to edit.
      
      Disadvantages:
        - Requires global writable data (though this is not a new requirement)
        - 1 new generated source file.

      Multiple-resolution encoder · aa7335e6
      Yunqing Wang authored
      The example encoder down-samples the input video frames a number of
      times with a down-sampling factor, and then encodes and outputs
      bitstreams with different resolutions.
      
      Support arbitrary down-sampling factor, and down-sampling factor
      can be different for each encoding level.
      
      For example, the encoder can be tested as follows.
      1. Configure with multi-resolution encoding enabled:
      ../libvpx/configure --target=x86-linux-gcc --disable-codecs
      --enable-vp8 --enable-runtime_cpu_detect --enable-debug
      --disable-install-docs --enable-error-concealment
      --enable-multi-res-encoding
      2. Run make
      3. Encode:
      If input video is 1280x720, run:
      ./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1
      (output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180).
      The last parameter is set to 1/0 to show/not show PSNR.)
      4. Decode:
      ./simple_decoder 1.ivf 1.yuv
      ./simple_decoder 2.ivf 2.yuv
      ./simple_decoder 3.ivf 3.yuv
      5. View video:
      mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30
      mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30
      mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30
      
      The encoding parameters can be modified in vp8_multi_resolution_encoder.c,
      for example, target bitrate, frame rate...
      
      Modified API. John helped a lot with that. Thanks!
