Struct SceneRunner 

pub struct SceneRunner { /* private fields */ }

Exclusive owner of the timeline decode pipeline.

Move to a background thread and call run. Register a FrameSink with set_sink before calling run.

Implementations

impl SceneRunner

pub fn set_sink(&mut self, sink: Box<dyn FrameSink>)

Register the frame sink. Call before run.

pub fn set_pacing(&mut self, pacing: Pacing)

Choose how frames are paced. Call before run; the default is Pacing::RealTime. Switching keeps the current position.

pub fn set_gpu_compositor(&mut self, compositor: Box<dyn PreviewCompositor>)

Register an external GPU compositor tried before the built-in CPU path. Call before run. avio supplies one over ff-render.

pub fn has_gpu_compositor(&self) -> bool

Whether an external GPU compositor is registered (else the CPU path is used).

pub fn run(self) -> Result<(), PreviewError>

A/V sync presentation loop.

Plays all clips in the primary video track from start to finish (or until a PlayerCommand::Stop is received).

Emits PlayerEvent::SeekCompleted after each successful seek, PlayerEvent::PositionUpdate after each presented video frame, PlayerEvent::Error on non-fatal decode errors, and PlayerEvent::Eof before returning.

Errors

Returns PreviewError::SeekOutOfRange if a seek command targets a timestamp that falls outside all clips on the timeline.

Trait Implementations

impl Drop for SceneRunner

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
