Struct Dpb 

pub struct Dpb<T> { /* private fields */ }

Implementations

impl<T: Clone> Dpb<T>

pub fn pictures(&self) -> impl Iterator<Item = Ref<'_, PictureData>>

Returns an iterator over the underlying H265 pictures stored in the DPB.

pub fn pictures_mut(&mut self) -> impl Iterator<Item = RefMut<'_, PictureData>>

Returns a mutable iterator over the underlying H265 pictures stored in the DPB.

pub fn len(&self) -> usize

Returns the length of the DPB.

pub fn is_empty(&self) -> bool

pub fn entries(&self) -> &Vec<DpbEntry<T>>

Get a reference to the whole DPB entries.

pub fn set_max_num_pics(&mut self, max_num_pics: usize)

Set the dpb’s max num pics.

pub fn max_num_pics(&self) -> usize

Get a reference to the dpb’s max num pics.

pub fn mark_all_as_unused_for_ref(&mut self)

Mark all pictures in the DPB as unused for reference.

pub fn find_ref_by_poc(&self, poc: i32) -> Option<DpbEntry<T>>

Finds a reference picture in the DPB using poc.

pub fn find_ref_by_poc_masked(&self, poc: i32, mask: i32) -> Option<DpbEntry<T>>

Finds a reference picture in the DPB using poc and mask.

pub fn find_short_term_ref_by_poc(&self, poc: i32) -> Option<DpbEntry<T>>

Finds a short term reference picture in the DPB using poc.

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

Drains the DPB by continuously invoking the bumping process.

pub fn needs_bumping(&mut self, sps: &Sps) -> bool

Whether the DPB needs bumping. See C.5.2.2.

pub fn bump(&mut self, flush: bool) -> Option<DpbEntry<T>>

See C.5.2.4 “Bumping process”.

pub fn needs_additional_bumping(&mut self, sps: &Sps) -> bool

See C.5.2.3. Happens when we are done decoding the picture.

pub fn clear(&mut self)

Clears the DPB, dropping all the pictures.

pub fn remove_unused(&mut self)

Removes all pictures which are marked as “not needed for output” and “unused for reference”. See C.5.2.2

pub fn store_picture( &mut self, picture: Rc<RefCell<PictureData>>, handle: T, ) -> Result<(), String>

Store a picture and its backend handle in the DPB.

pub fn get_all_references(&self) -> Vec<DpbEntry<T>>

Returns all the references in the DPB.
