libvlc-go

Handcrafted Go bindings for libVLC and high-level media player interface

The package can be useful for adding multimedia capabilities to applications through the provided player interfaces. It relies on Go modules in order to mirror each supported major version of libVLC.

Documentation for v3, which implements bindings for libVLC 3.X, can be found on pkg.go.dev.
Documentation for v2, which implements bindings for libVLC 2.X, can be found on pkg.go.dev.

Example applications:

• GUI media player
• GUI screen recorder
• GUI equalizer
• GUI media discovery

Prerequisites

The libVLC development files are required. Instructions for installing the VLC SDK on multiple operating systems can be found on the wiki pages of this project.

• Install on Linux
• Install on Windows
• Install on macOS

Installation

In order to support multiple versions of libVLC, the package contains a Go module for each major version of the API. Choose an installation option depending on the version of libVLC you want to use.

libVLC v3.X

go get github.com/adrg/libvlc-go/v3

libVLC v2.X

go get github.com/adrg/libvlc-go/v2

# Build for libVLC < v2.2.0
go build -tags legacy

All versions above also work for projects which are not using Go modules. However, consider switching to modules.

Examples

• GTK 3 media player (using gotk3)
• GTK 3 screen recorder (using gotk3)
• GTK 3 media discovery (using gotk3)
• GTK 3 equalizer (using gotk3)
• GTK 2 media player (using go-gtk)
• GTK 2 screen recorder (using go-gtk)
• Basic player usage
• Basic list player usage
• Handling events
• Retrieve media tracks
• Retrieve media information
• Display screen as player media
• Stream media to Chromecast
• Player equalizer usage

Examples for all supported API versions can be found at https://github.com/adrg/libvlc-go-examples.

Usage

package main

import (
    "log"

    vlc "github.com/adrg/libvlc-go/v3"
)

func main() {
    // Initialize libVLC. Additional command line arguments can be passed in
    // to libVLC by specifying them in the Init function.
    if err := vlc.Init("--no-video", "--quiet"); err != nil {
        log.Fatal(err)
    }
    defer vlc.Release()

    // Create a new player.
    player, err := vlc.NewPlayer()
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        player.Stop()
        player.Release()
    }()

    // Add a media file from path or from URL.
    // Set player media from path:
    // media, err := player.LoadMediaFromPath("localpath/test.mp4")
    // Set player media from URL:
    media, err := player.LoadMediaFromURL("http://stream-uk1.radioparadise.com/mp3-32")
    if err != nil {
        log.Fatal(err)
    }
    defer media.Release()

    // Retrieve player event manager.
    manager, err := player.EventManager()
    if err != nil {
        log.Fatal(err)
    }

    // Register the media end reached event with the event manager.
    quit := make(chan struct{})
    eventCallback := func(event vlc.Event, userData interface{}) {
        close(quit)
    }

    eventID, err := manager.Attach(vlc.MediaPlayerEndReached, eventCallback, nil)
    if err != nil {
        log.Fatal(err)
    }
    defer manager.Detach(eventID)

    // Start playing the media.
    err = player.Play()
    if err != nil {
        log.Fatal(err)
    }

    <-quit
}
