    VP9 level targeting: add a new AUTO mode · c3a6943c
    Hui Su authored
    In the new AUTO mode, restrict the minimum alt-ref interval and max column
    tiles adaptively based on picture size, while not applying any rate control
    constraints.
    
    This mode aims to produce encodings that fit into levels corresponding to
    the source picture size, with minimum compression quality lost. However, the
    bitstream is not guaranteed to be level compatible, e.g., the average bitrate
    may exceed level limit.
