      Add encoder control for setting color space · e94b415c
      Yaowu Xu authored
      This commit adds encoder side control for vp9 to set color space info
      in the output compressed bitstream.
      
      It also amends the "vp9_encoder_params_get_to_decoder" test to verify
      the correct color space information is passed from the encoder end to
      decoder end.

      Vidyo: Support for one-pass rc-enabled SVC encoder · 0ba1542f
      Deb Mukherjee authored
      Adds support for one-pass rc-enabled SVC encoder with callbacks for
      getting per-layer packets.
      - the callback function registration is implemented as an encoder
      control function.
      - if the callback function is not registered, the old way of
      aggregating packets with superframe will take effect.
      - one more control function “VP9E_GET_SVC_LAYER_ID” has been
      implemented to get the temporal/spatial id from the encoder
      within the callback. This can be used to get the ids to put on RTP
      packet.

      Add a new control of golden frame boost in CBR mode · 03a60b78
      Yaowu Xu authored
      0 means that golden boost is off, and uses average frame target rate,
      a non-zero number means the percentage of boost over average frame
      bitrate is given initially to golden frames in CBR mode.

      [spatial svc]Implement alt reference frames · e899859c
      Minghai Shang authored
      All changes are for spatial svc only.
      1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
      2. Use golden reference idx for spatial reference
      3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
      4. Add "auto-alt-refs" in svc options

      Mark VP8E_SET_ARNR_TYPE as being deprecated · a7657056
      Adrian Grange authored
      In a future release we plan to remove the
      option of setting the ARNR filter type.
      
      This patch marks this control as being deprecated
      as advance warning that it will be removed from
      the API at some point.

      Adrian Grange authored
      This reverts commit 59e733ca.
      
      Hold off removing arnr_type to give users the opportunity
      to change their script files to handle its deprecation. A
      follow-up patch will mark the control for setting arnr_type
      as deprecated and it will be removed completely in a later
      revision of the code.

      vpx_codec_vp9x_cx is not used internally. Experimental flag from
      vp9_extracfg is also not really used. YUV 4:4:4 just works after these
      changes (you have to specify --profile=1 for the encoder).

      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

      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.
