    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)
