      Separate frame context index for different frame types · 8915eb8e
      Jingning Han authored
      This commit makes the encoder to use different frame context index
      for different frame types. In the baseline setting, it sets the
      frame context index of the overlay frame to be different from other
      regular inter frames. In the ext-refs setting, it further allows
      the backward reference frame to use a different index.
      
      It improves the compression performance for both settings.
