Provided Methods§

source

fn negotiate(&self) -> Result<(), FlowError>

Negotiate with downstream elements to currently configured gst::Caps. Unmark GST_PAD_FLAG_NEED_RECONFIGURE in any case. But mark it again if negotiate fails.

§Returns

true if the negotiation succeeded, else false.

source

fn set_output_format(&self, caps: &Caps) -> Result<(), FlowError>

Configure output caps on the srcpad of self.

§caps

gst::Caps

§Returns

true on success.

source

fn allocator(&self) -> (Option<Allocator>, AllocationParams)

Lets AudioEncoder sub-classes to know the memory allocator used by the base class and its params.

Unref the allocator after use it.

§Returns
§allocator

the gst::Allocator used

§params

the gst::AllocationParams of allocator

source

fn set_headers(&self, headers: impl IntoIterator<Item = Buffer>)

Set the codec headers to be sent downstream whenever requested.

§headers

a list of gst::Buffer containing the codec header

source

fn sink_pad(&self) -> &Pad

source

fn src_pad(&self) -> &Pad

source

fn input_segment(&self) -> Segment

source

fn output_segment(&self) -> Segment
