A Rust crate that wraps the FFmpeg CLI binary with an intuitive Iterator interface for processing video as raw RGB frames.
FFmpeg Sidecar is a Rust crate that wraps the FFmpeg command-line interface (CLI) with an intuitive Iterator-based API. It enables Rust developers to process video files as sequences of raw RGB frames, abstracting the complexities of video decoding and encoding while leveraging FFmpeg's extensive format and codec support. The crate solves the problem of interacting with video data in a high-level, ergonomic way without dealing with low-level FFmpeg bindings.
Rust developers working with video processing, computer vision, or media applications who need a simple, cross-platform way to decode, encode, or manipulate video frames. It's particularly useful for those who prefer a CLI-based approach over low-level FFmpeg bindings.
Developers choose FFmpeg Sidecar because it offers a straightforward, iterator-based interface to FFmpeg with automatic binary downloads, cross-platform support, and rich metadata extraction—all without the build complexity of low-level bindings. Its unique selling point is treating video as an iterable stream of raw frames, making video processing feel native to Rust.

Downloads and installs the appropriate FFmpeg binary for Windows, macOS, or Linux if missing, eliminating manual installation and cross-platform headaches as highlighted in the README.
Provides a blocking iterator over video frames, enabling straightforward frame-by-frame processing that feels native to Rust, as shown in the 'Hello world' example.
Works seamlessly across Windows, macOS, and Linux with minimal dependencies, ensuring broad deployment support without complex toolchains.
Extracts progress updates, stream mappings, and errors from FFmpeg's stderr logs, offering better debugging and monitoring than raw CLI usage.
Spawning FFmpeg as a separate process for each operation introduces latency and resource usage, making it less suitable for high-throughput or real-time scenarios compared to direct library bindings.
Requires downloading and storing a ~100MB FFmpeg binary, which can bloat application size and complicate deployments in bandwidth-constrained or embedded environments.
As a CLI wrapper, it cannot access FFmpeg's internal APIs directly, restricting advanced features like custom filter graphs or fine-grained memory management available in crates like ffmpeg-sys-next.
