Provided Methods§

source

fn set_format( &self, state: &VideoCodecState<'static, Readable> ) -> Result<(), LoggableError>

source

fn parse( &self, frame: &VideoCodecFrame<'_>, adapter: &Adapter, at_eos: bool ) -> Result<FlowSuccess, FlowError>

source

fn handle_frame( &self, frame: VideoCodecFrame<'_> ) -> Result<FlowSuccess, FlowError>

§`frame`

The frame to handle

source

fn flush(&self) -> bool

source

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

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