Struct FrameHistogram 

pub struct FrameHistogram {
    pub timestamp: Duration,
    pub r: [u32; 256],
    pub g: [u32; 256],
    pub b: [u32; 256],
    pub luma: [u32; 256],
}

Per-channel color histogram for a single video frame.

Each array has 256 bins (one per 8-bit intensity level). For an N × M frame the sum of any channel’s bins equals N × M.

Luma is computed as Y = 0.299 R + 0.587 G + 0.114 B (BT.601 coefficients).

Fields

timestamp: Duration

Presentation timestamp of the sampled frame.

r: [u32; 256]

Red-channel bin counts.

g: [u32; 256]

Green-channel bin counts.

b: [u32; 256]

Blue-channel bin counts.

luma: [u32; 256]

Luma bin counts (BT.601 weighted average of R, G, B).
