This looks to me like a bug in the twolame.h header, where "TL_API" is missing in the line defining totwolame_encode_buffer_float32_interleaved(). Without this define, symbols get not exported in Windows. More important though: Why do you need libtwolame? There was mp2 encoding support in FFmpeg since day one...
