    libfdk-aacdec: Reduce the default decoder delay by one frame
    
    The default error concealment method if none is set via
    aacDecoder_SetParam(AAC_CONCEAL_METHOD) is set in
    CConcealment_InitCommonData within the fdk-aac library
    and is set to Energy Interpolation. This method requires one frame
    delay to the output. To reduce the default decoder output delay and
    avoid missing the last frame in file based decoding, use Noise
    Substitution as the default concealment method.
