AC4SampleEntry and Dolby AC-4 bitstream parameter conflicts

The AC4SampleEntry contains only basic parameters describing the audio bitstream and is intended to be used by the system for information purposes only. It is possible that differences may occur between the AC4SampleEntry and the parameters of the Dolby AC-4 bitstream (in which case, the information from the AC4SpecificBox must be ignored and the parameters of the Dolby AC-4 bitstream must be used for decoding purposes).
