Struct Vp9Packetizer 

pub struct Vp9Packetizer { /* private fields */ }

Available on crate feature ingest and (crate features rtsp or webrtc) only.

Packetizes VP9 coded frames into RTP, using a flexible-mode-off payload descriptor for the common single-layer (non-scalable) case.

Each frame is carried verbatim after a VP9 payload descriptor (the bytes are not transformed — VP9 RTP carries the frame opaquely), split across the MTU with the B (begin) bit on the first packet and E (end) + RTP marker on the last. A 15-bit picture ID increments per frame. Spatial/temporal scalability and flexible mode are out of scope.

Implementations

impl Vp9Packetizer

pub fn new(payload_type: u8, ssrc: u32, mtu: usize) -> Self

A VP9 packetizer for payload_type/ssrc. mtu is the maximum UDP payload; the 12-byte RTP header and a 3-byte descriptor are subtracted.

pub fn packetize( &mut self, frame: &[u8], timestamp: u32, keyframe: bool, ) -> Vec<Vec<u8>>

Packetize one VP9 frame at timestamp (90 kHz). keyframe clears the P (inter-predicted) bit so receivers can identify random-access points.
