Module frame 

Video and audio frame types.

This module provides VideoFrame and AudioFrame structures for working with decoded media frames. These types abstract away FFmpeg’s internal frame structures and provide a safe, Rust-idiomatic API.

Examples

Video Frame

use ff_format::{PixelFormat, PooledBuffer, Rational, Timestamp, VideoFrame};

// Create a simple 1920x1080 RGBA frame
let width = 1920u32;
let height = 1080u32;
let bytes_per_pixel = 4; // RGBA
let stride = width as usize * bytes_per_pixel;
let data = vec![0u8; stride * height as usize];

let frame = VideoFrame::new(
    vec![PooledBuffer::standalone(data)],
    vec![stride],
    width,
    height,
    PixelFormat::Rgba,
    Timestamp::default(),
    true,
).unwrap();

assert_eq!(frame.width(), 1920);
assert_eq!(frame.height(), 1080);
assert!(frame.is_key_frame());
assert_eq!(frame.num_planes(), 1);

Audio Frame

use ff_format::{AudioFrame, SampleFormat, Rational, Timestamp};

// Create a stereo F32 audio frame with 1024 samples
let channels = 2u32;
let samples = 1024usize;
let sample_rate = 48000u32;

let frame = AudioFrame::empty(
    samples,
    channels,
    sample_rate,
    SampleFormat::F32,
).unwrap();

assert_eq!(frame.samples(), 1024);
assert_eq!(frame.channels(), 2);
assert_eq!(frame.sample_rate(), 48000);
assert!(!frame.format().is_planar());
