Master audio and video processing in three minutes | Use FFmpeg gracefully in Rust

Popularity：31 ℃/2025-03-11 21:17:11

Preface

Audio and video processing seems unfathomable, but in development, we will more or less encounter related needs, such as video format conversion, editing, adding watermarks, audio extraction, etc.

As an industry standard, FFmpeg is almost omnipotent, and many popular software (such as VLC, YouTube, OBS) rely on it. However, FFmpeg also has something that makes developers headache:

  1. The entry threshold is high, you need to understandMultiplexing/demultiplexing, encoding and decoding, pixel format, sampling rateetc.
  2. C language implementation, it is easy to get involved in memory management when calling directly, and it may cause any carelessness.Memory leak, illegal access, program crashetc.
  3. The code is at the bottom and it is difficult to maintain, so if you are not careful, you will fall into a debugging nightmare.

RustMemory safe and powerful performanceKnown, then is there a simple, safe, and in our habits way to use FFmpeg in Rust?

ez-ffmpeg: Let Rust programmers use FFmpeg elegantly

ez-ffmpegLet you pass the same way as writing regular Rust codeChain callCreate and execute FFmpeg tasks.

It calls the underlying C code of FFmpeg using FFI andAutomatic memory management, so you don't need to worry about common memory security issues in C language.

Get started quickly: Use Rust to convert formats

Suppose we need to convert a video (or audio, picture) into format, usingez-ffmpegJust a few lines of code:

1. Install FFmpeg

If your environment has not installed FFmpeg, you can install it as follows:

macOS：

brew install ffmpeg

Windows：

vcpkg install ffmpeg
 # If it is the first time to install vcpkg, you also need to set the environment variable VCPKG_ROOT

2. Add Rust dependencies

existIntroducedez-ffmpeg：

[dependencies]
ez-ffmpeg = "*"

3. Run the code

use ez_ffmpeg::FfmpegContext;

 fn main() -> Result<(), Box<dyn std::error::Error>> {
     // 1. Build the FFmpeg context
     let context = FfmpegContext::builder()
         .input("input.mp4") // Input file
         .output("") // Output file
         .build()?;

     // 2. Start and wait for the task to complete
     ()?.wait()?;
     Ok(())
 }

It's that simple! You just needFocus on input and output，ez-ffmpegThis allows you to complete the format conversion.

Not just format conversion

ez-ffmpegIt can also be easily achievedVideo editing, audio and video extraction, filter addition, RTMP streaming, GPU accelerationand other functions.

Summarize

Compared with FFmpeg's command line method,ez-ffmpegLet Rust developersSeamless conversionFFmpeg command to the code, andNo additional learning of C language。

In addition, it supportsCustomize Filter and Input/Output, directly implemented with Rust, get rid of the complexity of C language extension and avoid the pain of FFmpeg compilation.
