Detailed Description

Video frame container.

A frame holds raw pixel data and basic metadata. The buffer is stored in row-major order in data.

Typical size relation:

data.size() >= stride * height

where stride is the number of bytes between two consecutive rows.

Note

The timestamp uses std::chrono::steady_clock and is monotonic.

Member Data Documentation

data

std::vector<std::uint8_t> yodau::backend::frame::data

Raw pixel bytes.

Layout is determined by format and stride.

Definition at line 74 of file frame.hpp.

format

pixel_format yodau::backend::frame::format { pixel_format::bgr24 }

Pixel format of the buffer.

Defaults to pixel_format::bgr24.

Definition at line 67 of file frame.hpp.

{ pixel_format::bgr24 };

height

int yodau::backend::frame::height { 0 }

Frame height in pixels.

Definition at line 53 of file frame.hpp.

{ 0 };

stride

int yodau::backend::frame::stride { 0 }

Number of bytes per row.

This may be wider than width * bytes_per_pixel due to alignment/padding.

Definition at line 60 of file frame.hpp.

{ 0 };

ts

std::chrono::steady_clock::time_point yodau::backend::frame::ts

Monotonic timestamp when the frame was captured/produced.

Definition at line 79 of file frame.hpp.

width

int yodau::backend::frame::width { 0 }

Frame width in pixels.

Definition at line 48 of file frame.hpp.
