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.
