Crate ff_pipeline 

ff-pipeline

Unified decode → filter → encode pipeline for the ff-* crate family.

This crate wires together ff-decode, ff-filter, and ff-encode into a single high-level API. All unsafe FFmpeg internals remain encapsulated in the underlying crates; users of ff-pipeline never need to write unsafe code.

Features

• Single-call transcode: open → filter → encode in one Pipeline::run()
• Progress callbacks: real-time frame-count and elapsed-time updates
• Cancellation: returning false from the progress callback aborts the pipeline
• Multi-input concatenation: pass multiple input paths to concatenate clips

Usage

use ff_pipeline::{Pipeline, EncoderConfig};
use ff_format::{VideoCodec, AudioCodec};
use ff_encode::BitrateMode;

let config = EncoderConfig::builder()
    .video_codec(VideoCodec::H264)
    .audio_codec(AudioCodec::Aac)
    .bitrate_mode(BitrateMode::Cbr(4_000_000))
    .resolution(1280, 720)
    .framerate(30.0)
    .build();

Pipeline::builder()
    .input("input.mp4")
    .output("output.mp4", config)
    .on_progress(|p| {
        println!("frame={} elapsed={:?}", p.frames_processed, p.elapsed);
        true // return false to cancel
    })
    .build()?
    .run()?;
