MPEG mode ID parsed from the bitstream. A 1 bit
indicates MPEG-1 audio. A 0 bit indicates a low-
sampling-rate MPEG-2 bitstream.
MPEG mode copyright bit from the bitstream. When set,
this bit indicates that the audio is copyright protected.
When cleared, this bit indicates no copyright.
MPEG mode_extension [1:0] parsed from the bitstream.
These bits are used in the joint_stereo mode. In Layer I
and II, they indicate which subbands are in intensity
