      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.

      Separated the speed dependent features into
      separate static and dynamic parts, the latter being
      those features that are dependent on the frame size.

      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'.

      [spatial svc]Multiple frame context feature · d4a407c0
      Minghai Shang authored
      We can use one frame context for each layer so that we don't have
      to reset the probs every frame. But we can't use prev_mi since we
      may drop enhancement layers. So we have to generate a non vp9
      compatible bitstream and modify it in the player.
      1. We need to code all frames as invisible frame to let prev_mi
         not to be used. But in the bitstream we need to code the
         show_frame flag to 1 so that the publisher will know it's
         supposed to be a visible frame.
      2. In the player we need to change the show_frame flag to 0 for
         all frames. Then add an one byte frame into the super frame
         to tell the decoder which layer we want to show.

      Choosing GOOD mode by default. · 8d363882
      Dmitry Kovalev authored
      This patch fixes slow first pass problem. Mode could only be determined
      from the deadline value during frame encode call. Unfortunately, we use
      mode value before any encode calls during the first pass encoding (see
      set_speed_features() logic). The mode for the first pass must be different
      from BEST to make first pass fast.

      Moving pass from VP9_COMP to VP9EncoderConfig. · 91c2f1e4
      Dmitry Kovalev authored
      We had a very complicated way to initialize cpi->pass from
      cfg->g_pass:
      switch (cfg->g_pass) {
        case VPX_RC_ONE_PASS:
          oxcf->mode = ONE_PASS_GOOD;
          break;
        case VPX_RC_FIRST_PASS:
          oxcf->mode = TWO_PASS_FIRST;
          break;
        case VPX_RC_LAST_PASS:
          oxcf->mode = TWO_PASS_SECOND_BEST;
          break;
      }
      
      cpi->pass = get_pass(oxcf->mode).
      
      Now pass is moved to VP9EncoderConfig and initialization is simple:
      switch (cfg->g_pass) {
        case VPX_RC_ONE_PASS:
          oxcf->pass = 0;
          break;
        case VPX_RC_FIRST_PASS:
          oxcf->pass = 1;
          break;
        case VPX_RC_LAST_PASS:
          oxcf->pass = 2;
          break;
      }
