experimental branch - ofxSingleSoundPlayer - endEvent works only a few times

[stephanschulz]

With ofxSingleSoundPlayer and example-matrixMixer:

I added to ofApp.cc loadFolder()

//	     players[startIndex + i]->setLoop(true);
            players[startIndex + i]->setLoop(false);
            if(!players[startIndex + i]->isLooping()){
                ofAddListener(players[startIndex + i]->endEvent, this, &ofApp::playerEnded);
            }

and

void ofApp::playerEnded(size_t & id){
    ofLog()<<"playerEnded() "<<id;
    players[id]->play();
}

The endEvent gets called a couple of times for some of the players and eventually I hear some piping noise and

the app crashes

[notice ] playerEnded() 1
[notice ] playerEnded() 3
[notice ] playerEnded() 2
[notice ] playerEnded() 3
[notice ] playerEnded() 4

When I add players[startIndex + i]->setId(startIndex + i);
inside if(!bLoadAsync){} then the play() call in playerEnded() works and the file "fake" loops correctly.

So, when using setId my 4 players have ids 0 to 3. When not using setId playerEnded() reports IDs 1-4.

Hi,
now the endEvent gets triggered regardless of the loop condition. Thus, it is not necessary to call play() from the callback.

when you don't set the id each player get assigned an unique id automatically.
also, when you call play() it returns the id of the instance that begun playing.
int playingId = players[0]->play();

good to the play() callback.

but I did see a crash when not setting any ID.
