Audio / Re: Trouble with sf::Music

I test my game in two case: use precompiled sfml and use git version.
If i use precompiled version game not play music, show message in console, and crashed because stack overflow. Messages similar to git version messages, but short (show source file, line number and short error type (exmpl.  AL_INVALID_OPERATION))
If i use git version game not play music and show message in console (first post).
It happened sometimes in debug version. In release all ok.

After i recompile all project file and library problem gone. I'm not sure that it's solving my problem, but program working.

About dll: i test my code with version on sfml-dev (and his dll), and with version on git (and his dll). I make this for get more detailed error report.

I don't know how repeat condition for generation my problem, and very strange that my problem generated sometimes.

My current code:

(click to show/hide)

#include <memory>
#include <list>

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

class MusicPlayer
{
        std::unique_ptr<sf::Music> musicPlayer;
        std::list<std::string> musicFiles;
        std::list<std::string>::iterator curMusicFile;
        void playNext()
        {
                musicPlayer->openFromFile(*(curMusicFile++));

                musicPlayer->play();
        }
public:
        void addMusic(const std::string& file)
        {
                musicFiles.push_back(file);
        }
        void doPlay()
        {
                if (!musicFiles.empty())
                {
                        if (!musicPlayer)
                        {
                                curMusicFile = musicFiles.begin();

                                musicPlayer = std::unique_ptr<sf::Music>(new sf::Music());

                                playNext();
                        }
                        else
                        {
                                if (musicPlayer->getStatus() == sf::SoundSource::Stopped)
                                {
                                        if (curMusicFile == musicFiles.end())
                                                curMusicFile = musicFiles.begin();

                                        musicPlayer->stop();

                                        playNext();
                                }
                        }
                }
        }
};

int main(int argc, char* argv[])
{
        sf::RenderWindow rwMain(sf::VideoMode(640, 480), "Test App", sf::Style::Default);
        rwMain.setFramerateLimit(60);

        MusicPlayer mp;
        mp.addMusic("1.ogg");

        sf::Clock clck;
        while (rwMain.isOpen())
        {
                mp.doPlay();

                sf::Event evItem;
                while (rwMain.pollEvent(evItem))
                {
                        if (evItem.type == sf::Event::Closed)
                                rwMain.close();
                }

                rwMain.clear(sf::Color::White);
                rwMain.display();
        }

        return 0;
}

My problem shown sometimes. In console shown messages (in first post) and music not played. And next program crashed. Many run my program work fine.
I don't understand reasons error.

Maybe, main reasons - it is my OS? I use OpenAL from distributibe SFML.

P.S. Messages show in console asynchronously. Sometimes message crossed. (exmpl. An internal iled in SoundSource.cpp(177) OpenAL call failed in SoundSource.cpp(177).)

Thanks for reply!

The my demo code is:

(click to show/hide)

#include <memory>
#include <list>

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

using namespace std;
using namespace sf;

class MusicPlayer
{
        std::unique_ptr<sf::Music> musicPlayer;
        sf::Time musicLength;
        sf::Time curLength;
        std::list<std::string> musicFiles;
        std::list<std::string>::iterator curMusicFile;
        void playNext()
        {
                musicPlayer->openFromFile(*(curMusicFile++));

                musicPlayer->play();

                curLength = musicPlayer->getPlayingOffset();
        }
public:
        void addMusic(const std::string& file)
        {
                musicFiles.push_back(file);
        }
        void doPlay(const sf::Time& delta)
        {
                if (!musicFiles.empty())
                {
                        if (!musicPlayer)
                        {
                                curMusicFile = musicFiles.begin();

                                musicPlayer = unique_ptr<Music>(new Music());

                                playNext();
                        }
                        else
                        {
                                curLength += delta;
                                if (curLength >= musicPlayer->getDuration())
                                {
                                        if (curMusicFile == musicFiles.end())
                                                curMusicFile = musicFiles.begin();

                                        musicPlayer->stop();

                                        playNext();
                                }
                        }
                }
        }
};

int main(int argc, char* argv[])
{
        RenderWindow rwMain(VideoMode(640, 480), "Test App", Style::Default);
        rwMain.setFramerateLimit(60);

        MusicPlayer mp;
        mp.addMusic("1.ogg");

        Clock clck;
        while (rwMain.isOpen())
        {
                mp.doPlay(clck.restart());

                Event evItem;
                while (rwMain.pollEvent(evItem))
                {
                        if (evItem.type == Event::Closed)
                                rwMain.close();
                }

                rwMain.clear(Color::White);
                rwMain.display();
        }

        return 0;
}
 

If i run this without creating window - all ok (infinite loop). I think, trouble generated in call sf::Music::play (may be i wrong).

I use SFML from git and from official site.
My OS: Windows 7 x64
My IDE: Visual Studio 2013
I build x32 application and x32 version sfml.

Audio / Trouble with sf::Music

« on: August 27, 2015, 01:12:34 pm »

Hello, i write simple game with SFML.
I using sf::Sound and all is ok. If i use sf::Music periodically i get error in console:

Please, tell me where my mistake. And sorry for my bad english.
