Struct SceneAdaptiveConfig

    pub target_bitrate: u64,
    pub frame_rate: f64,
    pub scene_cut_threshold: f32,

Expand description

Configuration for the scene-adaptive allocator.

Fields§

§target_bitrate: u64

Target average bitrate in bits per second.

§frame_rate: f64

Frame rate (frames per second).

§scene_cut_threshold: f32

SAD threshold for scene-cut detection (fraction of pixels that must differ; 0.0–1.0). Defaults to 0.15.

§min_scene_frames: u32

Minimum scene length in frames before another cut is allowed. Prevents very short “flash” scenes from dominating allocation.

§max_per_frame_ratio: f32

Maximum bit-allocation ratio per frame (clamp against wild swings). Default: 4.0 × average.

§min_per_frame_ratio: f32

Minimum bit-allocation ratio per frame. Default: 0.1 × average.
