/**
 * Enumeration used to define the possible video compression codings.
 * NOTE:  This essentially refers to file extensions. If the coding is
 *        being used to specify the ENCODE type, then additional work
 *        must be done to configure the exact flavor of the compression
 *        to be used.  For decode cases where the user application can
 *        not differentiate between MPEG-4 and H.264 bit streams, it is
 *        up to the codec to handle this.
