      [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.

      [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.

      [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

      Minghai Shang authored
            1. Save stats for each spatial layer
            2. Add frame buffer management for svc first pass rc
            3. Set default spatial layer to 1
            4. Flush encoder at the end of stream in test app
      This only supports spatial svc.

      create super fast rtc mode · ea8aaf15
      Jim Bankoski authored
      This patch only works if the video is a width and height that are both
      a multiple of 32..   It sets every partition to 16x16, and does INTRADC
      only on the first frame and ZEROMV on every other frame.   It always does
      does the largest possible transform, and loop filter level is set to 4.
      
      Was ~20% faster than speed -5 of vp8
      
      Now 20% slower but adds motion search ( every block ), nearest, near
      and zeromv
      
      The SVC test was changed because - while this realtime mode produces
      bad quality albeit quickly, it isn't obeying all the rules it should
      about which frames are available.

      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.

      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
