Crate waycap_rs

waycap-rs

waycap-rs is a high-level Wayland screen capture library with hardware-accelerated encoding. It provides an easy-to-use API for capturing screen content on Wayland-based Linux systems, using PipeWire for screen capture and hardware accelerated encoding for both video and audio.

Features

• Hardware-accelerated encoding (VAAPI and NVENC)
• No Copy approach to encoding video frames utilizing DMA Buffers
• Audio capture support
• Multiple quality presets
• Cursor visibility control
• Fine-grained control over capture (start, pause, resume)

Platform Support

This library currently supports Linux with Wayland display server and requires the XDG Desktop Portal and PipeWire for screen capture.

Example

use waycap_rs::{CaptureBuilder, QualityPreset, VideoEncoder, AudioEncoder};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a capture instance
    let mut capture = CaptureBuilder::new()
        .with_audio()
        .with_quality_preset(QualityPreset::Medium)
        .with_cursor_shown()
        .with_video_encoder(VideoEncoder::Vaapi)
        .with_audio_encoder(AudioEncoder::Opus)
        .build()?;
     
    // Start capturing
    capture.start()?;
     
    // Get receivers for encoded frames
    let video_receiver = capture.take_video_receiver();
    let audio_receiver = capture.take_audio_receiver()?;
     
    // Process frames as needed...
     
    // Stop capturing when done
    capture.close()?;
     
    Ok(())
}
