c++ - c++ sfml mp3音乐播放器错误

Question

我正在尝试使用mp3音乐文件播放器将音乐实现到游戏中，但它无法加载mp3(error1)文件，并且每次我按“E”键都将显示error(error2)。

error1: failed to open sound file "music.mp3" couldn't open stream

error2: Failed to play audio stream: sound parameters have not been initialized call initialize first

代码:

#include <SFML/Graphics.hpp>
#include <SFML\Audio.hpp>
#include <iostream>

const int WIDTH = 800;
const int HEIGHT = 800;
const std::string TITLE = "Game 2000";

int main()
{
    sf::RenderWindow window(sf::VideoMode(WIDTH, HEIGHT), TITLE);
    window.setVerticalSyncEnabled(true);
    sf::CircleShape shape(400.f);
    shape.setFillColor(sf::Color::Green);
    sf::Clock clock;

    sf::Music music;

    if (!music.openFromFile("music.mp3"))
        std::cout << "cannot find music.mp3" << std::endl;


    while (window.isOpen())
    {
        sf::Time time = clock.getElapsedTime();
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
            window.close();
        if (sf::Keyboard::isKeyPressed(sf::Keyboard::E))
            music.play();

        //std::cout << 1.0f / time.asSeconds() << std::endl;
        clock.restart().asSeconds();

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

我尝试了不同的格式，例如mp3 wav ogg，
没变。

错误2是跟进错误，因为加载未正确失败(这是SFML中的错误，或者曾经是SFML中的错误)。

您的实际问题是SFML不支持MP3文件。将该文件转换为WAV或OGG，然后重试。
