Provided Methods

fn update_conversion_info(&self)

Called when either the input or output formats have changed.

fn prepare_frame( &self, aggregator: &VideoAggregator, token: &AggregateFramesToken<'_>, buffer: &Buffer, ) -> Option<VideoFrame<Readable>>

Prepare the frame from the pad buffer and sets it to prepared_frame. Implementations should always return TRUE. Returning FALSE will cease iteration over subsequent pads.

fn clean_frame( &self, aggregator: &VideoAggregator, token: &AggregateFramesToken<'_>, frame: Option<VideoFrame<Readable>>, )

clean the frame previously prepared in prepare_frame
