is QtMultimedia available to use in go?

[Marc Poch]

Hello folks,

I'm trying to play an audio file in my go program. Because it already uses go-qml to display user interface I thought I could use QtMultimedia module.

But when I "import QtMultimedia 5.0" on the qml file, I get 'module "QtMultimedia" is not installed' error. Is this an error of my golang installation or it is because QtMultimedia module is not available in go?

Thanks

Hello, it's me again.

I would like to reformulate my question.

If I give a go file:

package main

import (
    "fmt"
    "os"
    "gopkg.in/qml.v1"
)

func main() {
    if err := qml.Run(run); err != nil {
        fmt.Fprintf(os.Stderr, "error: %v\n", err)
        os.Exit(1)
    }  
}

func run() error {
    engine := qml.NewEngine()
    component, err := engine.LoadFile("main.qml")
    if err != nil {
        return err
    }  

    window := component.CreateWindow(nil)

    window.Show()
    window.Wait()

    return nil
}

And a qml file:

import QtQuick 2.0
import QtMultimedia 5.0

Text {
    text: "Click Me!";
    font.pointSize: 24;
    width: 150; height: 50;

  Audio {
        id: playMusic
        source: "music.wav"
    }  
    MouseArea {
        id: playArea
        anchors.fill: parent
        onPressed:  { playMusic.play() }
    }  
}

compile with: GOBIN=. go install main.go

Does It works for you? If so, I must check my qt5 installation or my golang installation if not, maybe it means qtmultimedia is not available to use in golang.

Thanks in advance.

On my Mac, your qml file and go file worked expectedly. (I needed to make up "music.wav" but could played the audio)

I could create a binary by the `go install` command.

My environment:

Mac OS X (10.9.5)

go version: 1.4.1

Qt5 version: 5.4.0 (installed using brew)

Hello,

 Thanks for your time, now I know it must work. I will check my system and qt installation to solve the problem.

My environment:

GNU/Linux Gentoo (64bits)

go version: 1.4.1

qt5 version: 5.4.1
 

 Currently I'm installing qt-creator to test it with C++ and discover where my problem is.

 Thanks.

I just want to left the solution of my problem here, maybe it is useful to someone in the future.

My problem does not was related with go nor QML. It was because my system didn't have the plugins of gstreamer version 0.10 version does to play audio.

I'm glad I solved the problem, thanks.
