Struct TargetSizeSolver 

pub struct TargetSizeSolver {
    pub target_bytes: u64,
    pub duration_frames: u32,
    pub fps: f32,
}

Solves for the average bitrate (kbps) that achieves a target file size using binary search over the fill-factor-adjusted bitrate formula.

Fields

target_bytes: u64

Target output size in bytes.

duration_frames: u32

Number of frames in the segment.

fps: f32

Frame rate.

Implementations

impl TargetSizeSolver

pub fn new(target_bytes: u64, duration_frames: u32, fps: f32) -> Self

Creates a new solver.

pub fn solve_bitrate(&self, complexity_factor: f32) -> u32

Performs a binary search to find the bitrate (kbps) that fills target_bytes at the given complexity_factor [0.5, 2.0].

The complexity factor scales the effective fill factor (higher complexity → content is harder to compress → more bits needed per unit of quality), meaning the solver converges to a slightly higher bitrate for complex content.
