§tone_mapping_flag: u8

This flag indicates that the metadata for the tone mapping function in the processing window is present (for value of 1).

§knee_point_x: AVRational

The x coordinate of the separation point between the linear part and the curved part of the tone mapping function. The value shall be in the range of 0 to 1, excluding 0 and in multiples of 1/4095.

§knee_point_y: AVRational

The number of the intermediate anchor parameters of the tone mapping function in the processing window. The maximum value shall be 15.

§bezier_curve_anchors: [AVRational; 15]

The intermediate anchor parameters of the tone mapping function in the processing window in the scene. The values should be in the range of 0 to 1, inclusive and in multiples of 1/1023.

§color_saturation_mapping_flag: u8

This flag shall be equal to 0 in bitstreams conforming to this version of this Specification. Other values are reserved for future use.
