Progress value invalid for formats with indeterminate length

[nfranke]

If you try to play a file format for which the length cannot be calculated from the header, e.g. Sun AU, this call:

AudioFileStreamGetProperty(inAudioFileStream, kAudioFileStreamProperty_AudioDataByteCount, &byteCountSize, &audioDataByteCount);

doesn't produce an error, but it does set audioDataByteCount to 0xffffffff (i.e. a 32-bit -1 converted unsigned to 64-bit.) This makes the progress bar invalid since it thinks the duration is incredibly large.

You can change audioDataByteCount to a UInt32 and you still get back the same value as a UInt32.

Although it's a bit of a hack, this fixes the problem:

        error = AudioFileStreamGetProperty(inAudioFileStream, kAudioFileStreamProperty_AudioDataByteCount, &byteCountSize, &audioDataByteCount);

        if (!error && audioDataByteCount != 0xffffffff)
            currentlyReadingEntry->audioDataByteCount = audioDataByteCount;

Will probably need to add a progress that's in seconds rather than percentage of the duration since that'll be impossible to get for these type of streams.
