Ok. You can’t in a clean way.
I guess you decode the .oggs on loading and use them as sounds in
sdl_mixer. Or something equally complicated. I haven’t seen a good way
yet.

Good way as in.

THE_Sound *s = mix_loadafilethatcontainsaudiodata(“bla.mp3”);
THE_Sound *paralell = mix_loadafilethatcontainsaudiodata(“bananarama.ogg”);
mix_play(s);
mix-play(paralell);
//be happy

Actually yes, I do it almost like you say. Ripping my source to show
only the relevant lines,

   Mix_Chunk* m_pData;
   SDL_RWops* pRWOps = SDL_RWFromMem(pResource->getData(),
   pResource->getSize());
   m_pData = Mix_LoadWAV_RW(pRWOps, false);
   [...]
   return Mix_PlayChannel(0, m_pData, 0);

Instead of keeping telling me that the thing I’ve been doing for ages
doesn’t work, why don’t you just try it and see that it works?

wait…
are you decompressing the mp3 beforehand and then read use
Mix_LoadWAV_RW to create a mix_chunk from the decompressed data?

Really? I just tried loading a .mp3 through Mix_LoadWAV (through the
SDL_Mixer’s playwave example) and it didn’t work (Couldn’t load a.mp3:
Unrecognized sound file type)…

I’m really (happily) suprised about this. I really think you should change
the function name. You just need to add a macro like:
#define Mix_LoadSample Mix_LoadWAV
This will not break API or ABI compatibility and it would be not misleading.

Havin Mix_LoadWAV_RW load other formats too is a bit strange after all.
And if sdl_mixer is capable of that why didn’t they add a generic
load_compressedformatintosound() ?

As I said in the other email, I think there’s little doubt that the name
is indeed misleading. But hey, it works :slight_smile:
