      Add obu_sizing experiment. · 41150ad4
      Tom Finegan authored
      Writes PRE_OBU_SIZE_BYTES (currently 4) bytes padded unsigned LEB128
      encoded integers in OBU size fields when enabled:
      
      $ cmake path/to/aom -DCONFIG_OBU=1 -DCONFIG_OBU_SIZING=1 && cmake --build .
      
      Requires CONFIG_OBU.

      add scalability experiment · 2eeadab1
      Soo-Chul Han authored
      configure:  --enable-experimental --enable-scalability
      
      New applications:  scalable_encoder, scalable_decoder
      
      scalable_encoder:
        * Encodes inputs as 2-layer (same size) stream
        * Encodes as obu file (OBU_NO_IVF must be enabled)
        * Base layer encoded in IPPPP where P's reference
          only the previous (in time) base layer
        * Enhancement layer encoded using its base layer as
          sole reference frame
        * Base layer encoded with fixed high QP
        * Enhancement layer encoded with fixed low QP
      
      scalable_decoder:
        * Able to decode scalable stream generated by
          scalable_encoder
        * Able to decode any single-layer stream encoded
          by aomenc
        * Outputs base layer as out_lyr0.yuv, and enhancement
          layer (if they exist) as out_lyrN.yuv (N = 1, 2, 3, ..)
        * Able to decode N layers (more than 2)

      - Make the add_4bytes_obusize experiment part of the obu experiment.
      - Remove the add_4bytes_obusize experiment flags.
      - Update the encoder, decoder, and tooling sources.
