go-libav

Go language bindings for ffmpeg libraries.

This is still a work in progress. This package still lacks a lot of the libav's functionality. Please expect many additions/changes in the future.

Why

I am aware of other Go language bindings for ffmpeg. The reason I decided to build go-libav was because I wanted to have:

• A more Object-Oriented Programming approach.
• A more Go-like approach to error handling.
• Easier garbage collection.

Installation

First, install ffmpeg 3.x libraries on your system.

If you need ffmpeg2.x support, use ffmpeg2 branch (deprecated).

Then, open the terminal and install the following packages:

go get -u github.com/mgr9525/go-libav/avcodec
go get -u github.com/mgr9525/go-libav/avfilter
go get -u github.com/mgr9525/go-libav/avformat
go get -u github.com/mgr9525/go-libav/avutil

Documentation

For advanced usage, make sure to check the following documentation:

• avcodec
• avfilter
• avformat
• avutil

Examples

Please check here for examples.

FFmpeg versions

This library supports multiple versions of FFmpeg 3.x, to build, use

go build -tags ffmpeg33
go test -tags ffmpeg33
go run -tags ffmpeg33 examples/mediainfo/mediainfo.go

Use ffmpeg30 for FFmpeg 3.0 API, ffmpeg33 for FFmpeg 3.3 API.
