Expand description
Codec control function to set the min quant matrix flatness, unsigned int parameter
AOM can operate with different ranges of quantisation matrices. As quantisation levels increase, the matrices get flatter. This control sets the minimum level of flatness from which the matrices are determined.
By default, the encoder sets this minimum at half the available range.
