Trait SCStreamOutputTrait 

pub trait SCStreamOutputTrait: Send {
    // Required method
    fn did_output_sample_buffer(
        &self,
        sample_buffer: CMSampleBuffer,
        of_type: SCStreamOutputType,
    );
}

Trait for handling stream output

Implement this trait to receive callbacks when the stream captures frames or audio.

Examples

Using a struct

use screencapturekit::stream::{
    output_trait::SCStreamOutputTrait,
    output_type::SCStreamOutputType,
};
use screencapturekit::cm::CMSampleBuffer;

struct MyHandler;

impl SCStreamOutputTrait for MyHandler {
    fn did_output_sample_buffer(&self, sample: CMSampleBuffer, of_type: SCStreamOutputType) {
        match of_type {
            SCStreamOutputType::Screen => {
                println!("Received video frame");
            }
            SCStreamOutputType::Audio => {
                println!("Received audio buffer");
            }
            SCStreamOutputType::Microphone => {
                println!("Received microphone audio");
            }
        }
    }
}

Using a closure

Closures that match Fn(CMSampleBuffer, SCStreamOutputType) automatically implement this trait:

use screencapturekit::prelude::*;

let mut stream = SCStream::new(&filter, &config);

stream.add_output_handler(
    |_sample, _output_type| println!("Got frame!"),
    SCStreamOutputType::Screen
);

Required Methods

fn did_output_sample_buffer( &self, sample_buffer: CMSampleBuffer, of_type: SCStreamOutputType, )

Called when a new sample buffer is available

Parameters

• sample_buffer: The captured sample (video frame or audio buffer)
• of_type: Type of output (Screen, Audio, or Microphone)

Implementors

impl<F> SCStreamOutputTrait for F

where F: Fn(CMSampleBuffer, SCStreamOutputType) + Send + 'static,

Blanket implementation for closures

Any closure matching Fn(CMSampleBuffer, SCStreamOutputType) + Send + 'static can be used directly as an output handler.
