Struct CameraFrame 

pub struct CameraFrame {
    pub width: u32,
    pub height: u32,
    pub format: FrameFormat,
    pub rotation_degrees: u16,
    pub sequence: u64,
    pub bytes: Vec<u8>,
}

One frame from the viewfinder.

Fields

width: u32

height: u32

format: FrameFormat

rotation_degrees: u16

How far the frame must be rotated clockwise to be the right way up, which is the sensor’s mounting plus the device’s rotation.

sequence: u64

Which frame this is in the session, so a consumer can tell a repeat from a new one and count what it missed.

bytes: Vec<u8>

The pixels, in format.

Implementations

impl CameraFrame

pub fn new( width: u32, height: u32, format: FrameFormat, rotation_degrees: u16, sequence: u64, bytes: Vec<u8>, ) -> Option<Self>

A frame, or None when the bytes do not match the size and format — which is a backend bug, and one that reads as corrupted video rather than as an error if it is let through.

pub fn to_rgba8(&self) -> Vec<u8>

The frame as tightly packed RGBA8, converting only when it has to.

One pass over the bytes with no allocation beyond the result, because this runs per frame: a conversion that allocates per row shows up as dropped frames rather than as a slow function.
