Expand description

Codec control function to set the delta q mode, unsigned int parameter

AV1 supports a delta q mode feature, that allows modulating q per superblock.

  • 0 = deltaq signaling off
  • 1 = use modulation to maximize objective quality (default)
  • 2 = use modulation for local test
  • 3 = use modulation for key frame perceptual quality optimization
  • 4 = use modulation for user rating based perceptual quality optimization
