Provided Methods§

Source

fn read( &self, read_flags: RTPHeaderExtensionFlags, data: &[u8], buffer: &mut BufferRef, ) -> bool

Read the RTP header extension from data.

§read_flags

RTPHeaderExtensionFlags for how the extension should be written

§data

location to read the rtp header extension from

§buffer

a [gst::Buffer][crate::gst::Buffer] to modify if necessary

§Returns

whether the extension could be read from data

Source

fn write( &self, input_meta: &Buffer, write_flags: RTPHeaderExtensionFlags, output: &BufferRef, data: &mut [u8], ) -> Result<usize, BoolError>

Writes the RTP header extension to data using information available from the input_meta. data will be sized to be at least the value returned from RTPHeaderExtensionExt::max_size().

§input_meta

the input [gst::Buffer][crate::gst::Buffer] to read information from if necessary

§write_flags

RTPHeaderExtensionFlags for how the extension should be written

§output

output RTP [gst::Buffer][crate::gst::Buffer]

§data

location to write the rtp header extension into

§Returns

the size of the data written, < 0 on failure

Source

fn set_caps_from_attributes(&self, caps: &mut CapsRef) -> bool

RTPHeaderExtensionExt::set_id() must have been called with a valid extension id that is contained in these caps.

The only current known caps format is based on the SDP standard as produced by gst_sdp_media_attributes_to_caps().

§caps

writable [gst::Caps][crate::gst::Caps] to modify

§Returns

whether the configured attributes on self can successfully be set on caps

Source

fn set_caps_from_attributes_helper( &self, caps: &mut CapsRef, attributes: &str, ) -> bool

Helper implementation for GstRTPExtensionClass::set_caps_from_attributes that sets the self uri on caps with the specified extension id as required for sdp [gst::Caps][crate::gst::Caps].

Requires that the extension does not have any attributes or direction advertised in caps.

§caps

[gst::Caps][crate::gst::Caps] to write fields into

§Returns

whether the self attributes could be set on caps.

Source

fn update_non_rtp_src_caps(&self, caps: &mut CapsRef) -> bool

Updates depayloader src caps based on the information received in RTP header. caps must be writable as this function may modify them.

§caps

src [gst::Caps][crate::gst::Caps] to modify

§Returns

whether caps were modified successfully

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
