pub fn store_picture( &mut self, picture: RcPictureData, handle: Option<T>, ) -> Result<(), StorePictureError>

Store picture and its backend handle in the DPB.

pub fn has_empty_frame_buffer(&self) -> bool

Whether the DPB has an empty slot for a new picture.

pub fn needs_bumping(&self, to_insert: &PictureData) -> bool

Whether the DPB needs bumping, as described by clauses 1, 4, 5, 6 of C.4.5.3 “Bumping” process.

pub fn drain(&mut self) -> Vec<Option<T>>
