Crate ff_format 

ff-format

Common types for video/audio processing - the Rust way.

This crate provides shared type definitions used across the ff-* crate family. It completely hides FFmpeg internals and provides Rust-idiomatic type safety.

Module Structure

• pixel - Pixel format definitions (PixelFormat)
• sample - Audio sample format definitions (SampleFormat)
• time - Time primitives (Timestamp, Rational)
• frame - Frame types (VideoFrame, AudioFrame)
• stream - Stream info (VideoStreamInfo, AudioStreamInfo)
• media - Media container info (MediaInfo)
• color - Color space definitions (ColorSpace, ColorRange, ColorPrimaries)
• codec - Codec definitions (VideoCodec, AudioCodec)
• channel - Channel layout definitions (ChannelLayout)
• chapter - Chapter information (ChapterInfo)
• error - Error types (FormatError)

Usage

use ff_format::prelude::*;

// Access pixel formats
let format = PixelFormat::Yuv420p;
assert!(format.is_planar());

// Access sample formats
let audio = SampleFormat::F32;
assert!(audio.is_float());
assert_eq!(audio.bytes_per_sample(), 4);

// Work with timestamps
let time_base = Rational::new(1, 90000);
let ts = Timestamp::new(90000, time_base);
assert!((ts.as_secs_f64() - 1.0).abs() < 0.001);

// Access color and codec types
use ff_format::color::ColorSpace;
use ff_format::codec::VideoCodec;
let space = ColorSpace::Bt709;
let codec = VideoCodec::H264;
