This is used to know how much data a certain header extension will need for

be generated. Read more

fn set_direction(&self, direction: RTPHeaderExtensionDirection)
Set the direction that this header extension should be used in.
If
RTPHeaderExtensionDirection::INHERITED is included, the
direction will not be included in the caps (as it shouldn’t be in the
extmap line in the SDP). Read moreSource§fn set_non_rtp_sink_caps(&self, caps: &Caps) -> bool
fn set_non_rtp_sink_caps(&self, caps: &Caps) -> bool
Passes RTP payloader’s sink (i.e. not payloaded)
caps to the header
extension. Read moreSource§fn set_wants_update_non_rtp_src_caps(&self, state: bool)
fn set_wants_update_non_rtp_src_caps(&self, state: bool)
Call this function in a subclass from
GstRTPHeaderExtensionClass::read to
tell the depayloader whether the data just parsed from RTP packet require
updating its src (non-RTP) caps. If state is TRUE, RTPBaseDepayload will
eventually invoke RTPHeaderExtensionExtManual::update_non_rtp_src_caps() to
have the caps update applied. Applying the update also flips the internal
“wants update” flag back to FALSE. Read moreSource§fn wants_update_non_rtp_src_caps(&self) -> bool
fn wants_update_non_rtp_src_caps(&self) -> bool
Call this function after
RTPHeaderExtensionExtManual::read() to check if
the depayloader’s src caps need updating with data received in the last RTP
packet. Read moreSource§impl<O> RTPHeaderExtensionExtManual for Owhere
