      Modified resize unit test to output test vector · 88c8ff25
      Adrian Grange authored
      Modified the resize unit test so that it optionally
      writes the encoded bitstream to file. The macro
      WRITE_COMPRESSED_STREAM should be set to 1 to enable
      output of the test bitstream; it is set to 0 by default.

      Support a constant quality mode in VP9 · e378a89b
      Deb Mukherjee authored
      Adds a new end-usage option for constant quality encoding in vpx. This
      first version implemented for VP9, encodes all regular inter frames
      using the quality specified in the --cq-level= option, while encoding
      all key frames and golden/altref frames at a quality better than that.
      
      The current performance on derfraw300 is +0.910% up from bitrate control,
      but achieved without multiple recode loops per frame.
      
      The decision for qp for each altref/golden/key frame will be improved
      in subsequent patches based on better use of stats from the first pass.
      Further, the qp for regular inter frames may also be varied around the
      provided cq-level.

      Extension of segmentation to 8 segments. · 31ee193a
      Paul Wilkins authored
      Also some further simplification following removal
      of top node code.
      
      There is an issue in regards to the shared file vp8cx.h
      in regard to the roi_map as this interface assumes that
      there are only 4 segments. I have left the value here as
      4 for now meaning that the roi_map interface is broken
      for VP9.
      
      Note that this change would have been easier if I hadn't
      had to search for hard wire instances of the number 4
      and <= 3.

      [WIP] Add column-based tiling. · 1407bdc2
      Ronald S. Bultje authored
      This patch adds column-based tiling. The idea is to make each tile
      independently decodable (after reading the common frame header) and
      also independendly encodable (minus within-frame cost adjustments in
      the RD loop) to speed-up hardware & software en/decoders if they used
      multi-threading. Column-based tiling has the added advantage (over
      other tiling methods) that it minimizes realtime use-case latency,
      since all threads can start encoding data as soon as the first SB-row
      worth of data is available to the encoder.
      
      There is some test code that does random tile ordering in the decoder,
      to confirm that each tile is indeed independently decodable from other
      tiles in the same frame. At tile edges, all contexts assume default
      values (i.e. 0, 0 motion vector, no coefficients, DC intra4x4 mode),
      and motion vector search and ordering do not cross tiles in the same
      frame.
      t log
      
      Tile independence is not maintained between frames ATM, i.e. tile 0 of
      frame 1 is free to use motion vectors that point into any tile of frame
      0. We support 1 (i.e. no tiling), 2 or 4 column-tiles.
      
      The loopfilter crosses tile boundaries. I discussed this briefly with Aki
      and he says that's OK. An in-loop loopfilter would need to do some sync
      between tile threads, but that shouldn't be a big issue.
      
      Resuls: with tiling disabled, we go up slightly because of improved edge
      use in the intra4x4 prediction. With 2 tiles, we lose about ~1% on derf,
      ~0.35% on HD and ~0.55% on STD/HD. With 4 tiles, we lose another ~1.5%
      on derf ~0.77% on HD and ~0.85% on STD/HD. Most of this loss is
      concentrated in the low-bitrate end of clips, and most of it is because
      of the loss of edges at tile boundaries and the resulting loss of intra
      predictors.
      
      TODO:
      - more tiles (perhaps allow row-based tiling also, and max. 8 tiles)?
      - maybe optionally (for EC purposes), motion vectors themselves
        should not cross tile edges, or we should emulate such borders as
        if they were off-frame, to limit error propagation to within one
        tile only. This doesn't have to be the default behaviour but could
        be an optional bitstream flag.

      Pack invisible frames without lengths · 64bcffc1
      John Koleszar authored
      Modify the decoder to return the ending position of the bool decoder and
      use that as the starting position for the next frame.
      
      The constant-space algorithm for parsing the appended frame lengths is
      O(n^2), which is a potential DoS concern if n is unbounded. Revisit
      the appended lengths for use as partition lengths when multipartition
      support is added.
      
      In addition, this allows decoding of raw streams outside of a container
      without additional framing information, though it's insufficient to
      be able to remux said stream into a container.

      Packing Altref along with succeeding frame and length encoding frames · bc9670ee
      Vignesh Venkatasubramanian authored
      The altref frame is packed along with the next P frame. So that
      outside of the codec there are now only two types of frames P and I.
      Also, now it is one frame in and one frame out with respect to the
      codec. Apart from that, all the frames are length encoded with the
      length of each frame appended to the frame itself. There are
      two categories of frames and each of them will look as follows:
      
        - Packed frames (an altref along with the succeeding p frame)
          - altref_frame_data | altref_lenngth | frame_data | length
        - Unpacked frames (all frames other than the above)
          - frame_data | length

      Add lossless compression mode. · e44ee38a
      Hui Su authored
      This commit adds lossless compression capability to the experimental
      branch. The lossless experiment can be enabled using --enable-lossless
      in configure. When the experiment is enabled, the encoder will use
      lossless compression mode by command line option --lossless, and the
      decoder automatically recognizes a losslessly encoded clip and decodes
      accordingly.
      
      To achieve the lossless coding, this commit has changed the following:
          1. To encode at lossless mode, encoder forces the use of unit
      quantizer, i.e, Q 0, where effective quantization is 1. Encoder also
      disables the usage of 8x8 transform and allows only 4x4 transform;
          2. At Q 0, the first order 4x4  DCT/IDCT have been switched over
      to a pair of forward and inverse Walsh-Hadamard Transform
      (http://goo.gl/EIsfy),  with proper scaling applied to match the range
      of the original 4x4 DCT/IDCT pair;
          3. At Q 0, the second order remains to use the previous
      walsh-hadamard transform pair. However, to maintain the reversibility
      in second order transform at Q 0, scaling down is applied to first
      order DC coefficients prior to forward transform, and scaling up is
      applied to the second order output prior to quantization. Symmetric
      upscaling and downscaling are added around inverse second order
      transform;
          4. At lossless mode, encoder also disables a number of minor
      features to ensure no loss is introduced, these features includes:
              a. Trellis quantization optimization
              b. Loop filtering
              c. Aggressive zero-binning, rounding and zero-bin boosting
              d. Mode based zero-bin boosting
      
      Lossless coding test was performed on all clips within the derf set,
      to verify that the commit has achieved lossless compression for all
      clips. The average compression ratio is around 2.57 to 1.
