getDuration of audioclips on JSB doesn't work, always returns -1 about cocos-engine

[javierhoar]

Hi guys,

I was debugging this a bit to see why getDuration always returns -1 and I think I found a problem on AudioEngine-win32.cpp, and function "float AudioEngineImpl::getDuration(int audioID)"

Im doing this in code:
"var clip = "any.mp3";
cc.audioEngine.preload(clip , function(val){
var id = cc.audioEngine.playEffect(clip );
var dur = cc.audioEngine.getDuration(id)
});"

So when the getDuration is called, the audio is already loaded and playing. but still the result is -1.
I think the problem is here:

float AudioEngineImpl::getDuration(int audioID)
{
auto& player = _audioPlayers[audioID];
if(player._ready){
return player._audioCache->_duration;
} else {
return AudioEngine::TIME_UNKNOWN;
}
}

Because even thought player._audioCache->_duration has the right duration, the function always returns -1 because player._ready is false.

Could you please check?

Thanks in advance

I'm busy for other projects, I will take a look at this issue when I have time.
Yes, getDuration seems not to works well on Win32. :(
Need refactoring...

It is a very useful feature. Hope you can fix it.

Thanks in advance.

There is no such problem in 2.4.x and 3.0.0 versions.
