      Modified spatial scalable encoder & unit tests · 475d1d60
      Adrian Grange authored
      Modifications to the spatial scalable encoder to match
      changes made to the scaling code in the decoder.
      
      In particular, the use of a dummy first frame was removed
      now that the decoder is able to handle a smaller first
      frame.
      
      SvcTest.FirstFrameHasLayers unit test re-enabled.

      Fix decoder to handle display size correctly · 2117fe05
      Adrian Grange authored
      The decoder ignored the display width & height
      specified in the frame header.
      
      This patch adds a control, VP9D_GET_DISPLAY_SIZE, to
      allow the application to obtain the display width and
      height from the frame header.
      
      vpxdec has been modified to scale the output frame to
      this size.
      
      Should the request for the display size fail vpxdec will
      use the native width and height of the raw decoded
      frame instead.

      Move SVC per-frame loop from sample app into libvpx proper · 1ed0e1be
      Ivan Maltz authored
      SVC multiple layer per frame encoding is invoked with vpx_svc_init and
      vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
      Additional improvements:
      - make dummy frame handling a bit more explicit
      - fixed bug with single layer encodes
      - track individual frame sizes and psnrs instead of averages
      - parameterized quantizer, 16th scalefactors, more logging,
      - enabled single layer encodes to generate baseline
      - include new mode for 3 layer I frame with 5 total layers

      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.
