Struct ContentLightLevel 

Source
pub struct ContentLightLevel {
    pub max_cll: u16,
    pub max_fall: u16,
}
Expand description

HDR10 Content Light Level Information per CTA-861.3 / HEVC SEI 144 (content_light_level_info) / AV1 Metadata OBU METADATA_TYPE_HDR_CLL. Wire-encoded into the MP4 clli box as 2 × u16 BE, total 4 bytes payload.

Units (per the spec):

  • max_cll — Maximum Content Light Level, peak luminance of the brightest pixel anywhere in the stream, in cd/m² (integer nits).
  • max_fall — Maximum Frame-Average Light Level, peak per-frame average luminance, in cd/m² (integer nits).

Field-name contract with Squad-21: load-bearing names; do not rename without coordinating.
