Struct V4l2M2mEncoder 

pub struct V4l2M2mEncoder { /* private fields */ }

Implementations

impl V4l2M2mEncoder

pub fn new( codec: Codec, settings: &RustCaptureSettings, rgba: bool, ) -> Result<Self, String>

pub fn codec(&self) -> Codec

pub fn is_fullcolor(&self) -> bool

The firmware converts to 4:2:0 and the encoder takes nothing else.

pub fn last_reference(&self) -> Reference

The kernel’s stateful interface names no reference and takes no invalidation.

pub fn invalidate_reference(&mut self, _frame_id: u16) -> bool

pub fn is_full_range(&self) -> bool

The range the stream declares, which is the device’s to decide: a session that says nothing is described as limited, since that is what a decoder given nothing assumes.

pub fn reconfigure_rate( &mut self, settings: &RustCaptureSettings, ) -> Result<(), String>

Apply a live bitrate or frame rate change. Both are writable while streaming on this path, and the frame rate goes down with the bitrate: left behind, it would budget a new bitrate against an old rate.

pub fn encode_host( &mut self, pixels: &[u8], stride: usize, _rgba: bool, frame_number: u64, _qp: u32, force_idr: bool, ) -> Result<Vec<u8>, String>

Trait Implementations

impl Drop for V4l2M2mEncoder

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
