Struct MutterCapture 

pub struct MutterCapture { /* private fields */ }

Mutter ScreenCast + PipeWire capture backend.

Implementations

impl MutterCapture

pub fn new(state: Arc<MutterState>) -> Self

Create a new capture backend from shared compositor state.

Trait Implementations

impl CaptureBackend for MutterCapture

fn start_stream<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<PipeWireStream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start a PipeWire capture stream. The returned PipeWireStream stays alive until explicitly stopped.

fn stop_stream<'life0, 'async_trait>( &'life0 self, stream: PipeWireStream, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stop a previously started stream and release backend-side resources.

fn pipewire_socket(&self) -> PathBuf

Path to the PipeWire socket the shared GStreamer helper should talk to (usually <runtime_dir>/pipewire-0).

fn grab_screenshot<'life0, 'life1, 'async_trait>( &'life0 self, stream: &'life1 PipeWireStream, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Capture a PNG from an already-running stream.

fn start_recording<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, stream: &'life1 PipeWireStream, output_path: &'life2 Path, bitrate: u32, fps: u32, ) -> Pin<Box<dyn Future<Output = Result<VideoRecorder, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Start a continuous WebM recording of stream written to output_path at the given bitrate (bits/sec) and fps. Returns a handle whose stop() must be awaited to finalize the file cleanly.

fn stop_recording<'life0, 'async_trait>( &'life0 self, recorder: VideoRecorder, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Stop a previously-started recording, flushing the WebM seekhead/cues before returning.
