Provided Methods§

Source

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

Negotiate with downstream elements to currently configured AudioInfo. 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_caps(&self, caps: &Caps) -> Result<(), FlowError>

Configure output caps on the srcpad of self. Similar to set_output_format(), but allows subclasses to specify output caps that can’t be expressed via AudioInfo e.g. caps that have caps features.

§caps

(fixed) [gst::Caps][crate::gst::Caps]

§Returns

true on success.

Source

fn set_output_format(&self, info: &AudioInfo) -> Result<(), FlowError>

Configure output info on the srcpad of self.

§info

AudioInfo

§Returns

true on success.

Source

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

Lets AudioDecoder 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][crate::gst::Allocator] used

§params

the [gst::AllocationParams][crate::gst::AllocationParams] of allocator

Source

fn error<T: MessageErrorDomain>( &self, weight: i32, code: T, message: Option<&str>, debug: Option<&str>, file: &str, function: &str, line: u32, ) -> Result<FlowSuccess, FlowError>

Source

fn sink_pad(&self) -> &Pad

Source

fn src_pad(&self) -> &Pad

Source

fn input_segment(&self) -> Segment

Source

fn output_segment(&self) -> Segment

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.
