MP3 format is supported. The Decode() fails for the last frame, but Probe() api should return E_SUCCESS if the source buffer is loaded correctly. 

Hi,
At minimum test.mp3 from Sample->mediaApp is decoded successfully
Maybe you have missed codec type in dec.Construct(CODEC_MP3);

But there is another problem was observed during decoding. Second attempt to use the same AudioDecoder object was not success. Looks like AudioDecoder ::Reset() method does not work:
