After compiling the binaries (had to use -fpermissive [1]), this is what I get: ------------------ $ ./playsound_simple ../scream.mp3 Now playing [../scream.mp3]... Error decoding file: (null) $ ./playsound ../scream.mp3 Now playing [../scream.mp3]... Error in decoding sound file! reason: [MPGLIB: Free format not supported.]. ------------------ So it seems that the .mp3 that you are playing is not supported by the library. From this reply of the author in the support mailing list (from 2007, but the code does not seem to have changed much since then, and indeed the code seems very fragile): ------------------ http://icculus.org/pipermail/sdlsound/2007-January/000655.html mpglib is deeply unforgiving about file corruption...it gives up immediately when it sees data it doesn't expect, which is a problem with a lot of mp3s out there. Also, unfortunately, one of the things it doesn't expect is ID3v2 tags, so that excludes the vast majority of mp3s created in the past few years. This is fairly easy to fix, just no one ever has (for ID3v1, we just look for the struct in the last 128 bytes of the mp3, and don't pass it to mpglib if we see it. ID3v2's layout is somewhat more complicated, but something similar can still be done). In a more ideal world, someone would take the time to understand the mpglib code and make it recover from bad data. Or replace it with a different mp3 decoder, but I haven't found one that isn't GPL'd. SDL_sound's SMPEG backend is more forgiving of strange data, but has its own problems too. Use Ogg files if you control your content. :) As you can tell by my long apology here, we're sort of at the mercy of a disproportionate amount of third-party code here. ------------------ Cheers. -- Manuel A.
