Implementations

impl Arm

fn alignment(&self) -> (u32, u32)

The surface alignment the codec’s blocks want.

fn wanted_packed(&self) -> u32

The packed headers the codec writes itself.

fn tracks_references(&self, packed: u32) -> bool

Whether the session can name what a frame predicts from and leave a lost one out: the codecs whose headers the session writes need the driver to take them, since a driver writing its own slice headers names the references it chooses.

fn sequence(&mut self, negotiated: &Negotiated, out: &mut Buffers)

fn level(&self) -> u32

The level the codec’s sequence names for the configured geometry and rate, zero for a codec that names none.

fn picture( &mut self, negotiated: &Negotiated, frame: &Frame<'_>, out: &mut Buffers, ) -> Result<(), String>
