Expand description

Frame complexity metrics for bitrate allocation.

Fields§

§frame_index: u64

Frame index in the stream.

§frame_type: FrameType

Frame type (Key, Inter, BiDir).

§spatial_complexity: f64

Spatial complexity (0.0-1.0, based on variance).

§temporal_complexity: f64

Temporal complexity (0.0-1.0, based on motion).

§combined_complexity: f64

Combined complexity metric.

§sad: u64

Sum of Absolute Differences with previous frame.

§variance: f64

Average luma variance across blocks.

§encoding_difficulty: f64

Estimated encoding difficulty (1.0 = average).

§is_scene_change: bool

Is this frame a scene change.
