@NAME : RewindMPEG
@INPUT : MPEGfile - the input stream where the MPEG's coming from
Image - image descriptor (just passed to OpenMPEG ())
@OUTPUT : (none)
@RETURNS : (void)
@DESCRIPTION: Resets things so that the caller can start reading the MPEG
stream from the start again. Note that the caller does NOT
need to call OpenMPEG() again -- after a call to RewindMPEG(),
the next call to GetMPEGFrame() will return the first frame
of the MPEG.
@METHOD :
@GLOBALS : EOF_flag, curBits, bitOffset, bufLength, bitBuffer, totNumFrames
@CALLS :
@CREATED : 94/7/20, Greg Ward
@MODIFIED :
@COMMENTS : The global variables declared in this function should
not normally be used by the front end to the MPEG
decoder. However, I've chosen to bend the rules for
just this one function. N.B.: EOF_flag comes from
globals.c; curBits, bitOffset, bufLength, and bitBuffer
from util.c; and totNumFrames is defined in this file.
