Struct MockVideoStream 

pub struct MockVideoStream {
    width: u32,
    height: u32,
    frame_rate: f32,
    total_frames: u64,
    next_index: u64,
}

A scrolling-gradient mock: each frame phase-shifts a smooth RGB gradient across the surface. Visually obvious motion; mathematically deterministic.

Fields

width: u32

height: u32

frame_rate: f32

total_frames: u64

next_index: u64

Implementations

impl MockVideoStream

pub fn scrolling_gradient(width: u32, height: u32, total_frames: u64) -> Self

Build a scrolling-gradient stream with the given dimensions and total frame count. Plays at 30 fps.

pub fn with_frame_rate(self, fps: f32) -> Self

Override the frame rate (used by player-pacing tests).

Trait Implementations

impl VideoStream for MockVideoStream

fn width(&self) -> u32

Frame width in pixels. Constant across the stream.

fn height(&self) -> u32

Frame height in pixels. Constant across the stream.

fn frame_rate(&self) -> f32

Source frame rate (frames per second). Used by the player loop to time uploads; backends without a known fixed rate may return their nominal rate (e.g. AVFoundation’s nominalFrameRate on the track).

fn frame_count_hint(&self) -> Option<u64>

Total frame count, if known up-front. None for live streams.

fn next_frame(&mut self) -> Option<VideoFrame>

Pull the next frame. Returns None at end-of-stream.
