pub const AV1E_SET_AQ_MODE: aome_enc_control_id = 40;

Codec control function to set adaptive quantization mode, unsigned int parameter

AV1 has a segment based feature that allows encoder to adaptively change quantization parameter for each segment within a frame to improve the subjective quality. This control makes encoder operate in one of the several AQ modes supported.

• 0 = disable (default)
• 1 = variance
• 2 = complexity
