Struct AVAmbientViewingEnvironment

#[repr(C)]
pub struct AVAmbientViewingEnvironment {
    pub ambient_illuminance: AVRational,
    pub ambient_light_x: AVRational,
    pub ambient_light_y: AVRational,
}

Ambient viewing environment metadata as defined by H.274. The values are saved in AVRationals so that they keep their exactness, while allowing for easy access to a double value with f.ex. av_q2d.

@note sizeof(AVAmbientViewingEnvironment) is not part of the public ABI, and it must be allocated using av_ambient_viewing_environment_alloc.

Fields

ambient_illuminance: AVRational

Environmental illuminance of the ambient viewing environment in lux.

ambient_light_x: AVRational

Normalized x chromaticity coordinate of the environmental ambient light in the nominal viewing environment according to the CIE 1931 definition of x and y as specified in ISO/CIE 11664-1.

ambient_light_y: AVRational

Normalized y chromaticity coordinate of the environmental ambient light in the nominal viewing environment according to the CIE 1931 definition of x and y as specified in ISO/CIE 11664-1.
