go-media ffmpeg bindings

This package provides bindings for some parts of the ffmpeg API including libavformat, libavcodec and libavutil.

This package is part of a wider project, github.com/djthorpe/go-media. Please see the module documentation for more information.

Introduction

You can use this package to access the ffmpeg API from Go. For example, in order to read the metadata and streams in a media file, use:

func main() {
    ctx := ffmpeg.NewAVFormatContext()
    err := ctx.OpenInput(os.Args[1], nil)
    if err != nil {
        panic(err)
    }
    defer ctx.CloseInput()
    fmt.Println("metadata=",ctx.GetMetadata())
}

You could also use this package to write a media file. For example, to create a video file from a video stream:

TODO

Media Input

Reading from a Path
Reading from a URL
Reading from an io.Reader

Media Output

Writing to Path
Writing to an io.Writer

Formats

TODO

Codecs
