      Account for rate error in GF group Q calculation. · 8d7f53f0
      paulwilkins authored
      When GF group adaptive maxQ is enabled this patch accounts
      somewhat for accumulated error in the rate control.
      
      This improves accuracy quite a bit on many clips especially
      when there is  overshoot.
      
      Examples when the overshoot and undershoot command line
      parameters are set to 100:
      
      Hall @ 1200 overshoot is reduced from 67-24%.
      Akiyo @ 400 undershoot is reduced from 28%-15%.
      
      Setting a lower value for undershoot or overshoot still
      reduces the error further.
      
      Impact on metrics is mixed with some gains in average psnr
      but generally a little lower (e.g. 0.5%) on overall and ssim.
      
      The GF group adaptation is still off by default in this patch.
      Compared to with the head, enabling this mode now gives
      big average psnr gains on the YT sets (e.g. YT_HD >11.2%),
      a drop in overall PSNR (YT-HD 3.9%) and a smaller drop or
      neutral for SSIM.

      Try again to merge branch 'frame-parallel' into master branch. · be6aeada
      hkuang authored
      In frame parallel decode, libvpx decoder decodes several frames on all
      cpus in parallel fashion. If not being flushed, it will only return frame
      when all the cpus are busy. If getting flushed, it will return all the
      frames in the decoder. Compare with current serial decode mode in which
      libvpx decoder is idle between decode calls, libvpx decoder is busy
      between decode calls.
      
      Current frame parallel decode will only speed up the decoding for frame
      parallel encoded videos. For non frame parallel encoded videos, frame
      parallel decode is slower than serial decode due to lack of loopfilter
      worker thread.
      
      There are still some known issues that need to be addressed. For example:
      decode frame parallel videos with segmentation enabled is not right sometimes.
      
      * frame-parallel:
        Add error handling for frame parallel decode and unit test for that.
        Fix a bug in frame parallel decode and add a unit test for that.
        Add two test vectors to test frame parallel decode.
        Add key frame seeking to webmdec and webm_video_source.
        Implement frame parallel decode for VP9.
        Increase the thread test range to cover 5, 6, 7, 8 threads.
        Fix a bug in adding frame parallel unit test.
        Add VP9 frame-parallel unit test.
        Manually pick "Make the api behavior conform to api spec." from master branch.
        Move vp9_dec_build_inter_predictors_* to decoder folder.
        Add segmentation map array for current and last frame segmentation.
        Include the right header for VP9 worker thread.
        Move vp9_thread.* to common.
        ctrl_get_reference does not need user_priv.
        Seperate the frame buffers from VP9 encoder/decoder structure.

      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.

      vp9_ethread: the tile-based multi-threaded encoder · eba9c762
      Yunqing Wang authored
      Currently, VP9 supports column-tile encoding, which allows a frame
      to be encoded in multiple column tiles independently. The number of
      column tiles are set by encoder option "--tile-columns". This
      provides a way to encode a frame in parallel.
      
      Based on previous set of patches, this patch implemented the tile-
      based multi-threaded encoder. Each thread processes one or more
      tiles.
      
      Usage:
      For HD clips:
      --tile-columns=2 --threads=1/2/3/4
      
      While using 4 threads, tests showed that the encoder achieved
      2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at
      realtime speed 5.

      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.

      [spatial svc]Another workaround to avoid using prev_mi · c113457a
      Minghai Shang authored
      We encode a empty invisible frame in front of the base layer frame to
      avoid using prev_mi. Since there's a restriction for reference frame
      scaling factor, we have to make it smaller and smaller gradually until
      its size is 16x16.

      Adds high bitdepth transform functions and tests · 10783d4f
      Deb Mukherjee authored
      Adds various high bitdepth transform functions and tests.
      Much of the changes are related to using typedefs tran_low_t
      and tran_high_t for the final transform cofficients and intermediate
      stages of the transform computation respectively rather than fixed
      types int16_t/int. When vp9_highbitdepth configure flag is off,
      these map tp int16_t/int32_t, but when the flag is on, they map
      to int32_t/int64_t to make space for needed extra precision.

      Removing alg_priv from vpx_codec_priv struct. · 73edeb03
      Dmitry Kovalev authored
      In order to understand memory layout consider the declaration of the
      following structs. The first one is a part of our API:
      
      struct vpx_codec_ctx {
        // ...
        struct vpx_codec_priv *priv;
      };
      
      The second one is defined in vpx_codec_internal.h:
      
      struct vpx_codec_priv {
        // ...
      };
      
      The following struct is defined 4 times for encoder/decoder VP8/VP9:
      
      struct vpx_codec_alg_priv {
        struct vpx_codec_priv base;
        // ... 
      };
      
      Private data allocation for the given ctx:
      
      struct vpx_codec_ctx *ctx = <get>
      struct vpx_codec_alg_priv *alg_priv = <allocate>
      ctx->priv = (struct vpx_codec_priv *)alg_priv;
      
      The cast works because vpx_codec_alg_priv has a
      vpx_codec_priv instance as a first member 'base'.
