Provided Methods§

fn handle_frame( &self, buffer: Option<&Buffer> ) -> Result<FlowSuccess, FlowError>

source

fn pre_push(&self, buffer: Buffer) -> Result<Option<Buffer>, FlowError>

source

fn flush(&self)

source

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

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.
