Struct VirtualCapture 

pub struct VirtualCapture { /* private fields */ }

Simple virtual capture backend that emits patterned frames from a buffer pool.

Example

use styx_capture::prelude::*;

let pool = BufferPool::with_capacity(1, 128);
let res = Resolution::new(4, 4).unwrap();
let format = MediaFormat::new(FourCc::new(*b"RG24"), res, ColorSpace::Srgb);
let mode = Mode {
    id: ModeId { format, interval: None },
    format,
    intervals: smallvec::smallvec![],
    interval_stepwise: None,
};
let source = VirtualCapture::new(mode, pool, 3);
let frame = source.next_frame().unwrap();
assert_eq!(frame.meta().format.code.to_string(), "RG24");

Implementations

impl VirtualCapture

pub fn new( mode: Mode, pool: BufferPool, bytes_per_pixel: usize, ) -> VirtualCapture

Create a virtual source using the provided mode and pool.

pub fn tick( &self, _config: &CaptureConfig, sink: &BoundedTx<FrameLease>, ) -> SendOutcome

Emit a single frame and return whether it was accepted by the downstream queue.

Trait Implementations

impl CaptureSource for VirtualCapture

fn descriptor(&self) -> &CaptureDescriptor

Descriptor for this source.

fn next_frame(&self) -> Option<FrameLease>

Pull the next frame; concrete backends decide how to block/yield.
