Struct FrameTransform 

pub struct FrameTransform { /* private fields */ }

A callback over encoded frames, to be attached to a transceiver’s sender/receiver; see the module docs.

This is a registration, not a native object. Attaching it does not take libwebrtc’s single SetFrameTransformer slot — the crate owns one transformer per sender and per receiver, and composes this callback with its own frame-metadata step (see crate::metadata). That is what lets a caller use encoded-frame access and per-frame metadata on the same transceiver, which a single slot cannot express.

Attaching the same FrameTransform to more than one sender/receiver shares one callback, serialised by its mutex.

Implementations

impl FrameTransform

pub fn new( cb: impl for<'a> FnMut(&EncodedFrame<'a>) -> FrameAction + Send + 'static, ) -> Self

Create a transform running cb per encoded frame. The closure runs on a WebRTC thread and must not block it.

Trait Implementations

impl Clone for FrameTransform

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
