Just thought I would share my progress.
I've just listened to Big Wednesday - Jack & Mary, an ogg file I found on my Trackmania dvd Smiley

It really wasn't that hard at all, the thing that took me time was that I used a faulty implementation of qsort(). The effect of this was that it sometimes crashed, sometimes not...

I'm going to build a very simple audio player and then release Smiley

I was working a bit on adapting this to my buffer solution I use for raw audio... but right now it doesn't want to as I want it to. I'm going to get some sleep and then look at it again.

Anyway, here is the library and a simple sample how to use it:
http://www.harteex.com/files/SimpleSoundVorbis.zip

It plays test.ogg in the same directory as the executable.
Exit with Start+Select.

Sound is not perfect, because it needs buffering!
This is just a basic sample.

An update.

Now it's possible to use an ogg file from memory / buffer, good for embedding Smiley

http://www.harteex.com/files/SimpleSoundVorbis3.zip

To compile, there has to be an ogg file named oggTest.ogg in the res directory, and then you need to run create_resources_sound.bat.

The sound actually sounds quite good now, even thought there is no buffering.


I still haven't got buffering running ok, it sounds like it's slow. It sounds like it's too slow decoding, but I don't think so, it's probably a bug somewhere.

Here is my work in progress. If anyone wants to play around with it and finds something bad with the code, I would love to hear.

EDIT: Found the problem
I wrongfully assumed that ogg would always give back the amount of data that was requested.

EDIT 2: While a lot better, still not perfect Sad

EDIT 3: Ok now everything works.

EDIT 4: See http://boards.dingoonity.org/dingoo-releases/gooplayer-(ogg-music-player)/

You're amazing man... you've simply saved my life!!!!!!!!

I'm wondering if it will be compatible with a game... I need to update the screen at 24fps so if I could have this running with the game engine, I'll just will kiss you xDDDDDD

Thanks again, you're the one.

Go get SameGoo (source) to see the ogg functionality in action in a game Smiley
