This class compresses a sequence of frames/fields, frame by frame. or field by field. It currently uses GOP parameters set in the encoder parameters in order to define the temporal prediction structure. A version to incorporate non-GOP structures is TBC.<p>

This function codes the next picture in coding order and returns the next picture in display order. In general these will differ, and because of re-ordering there is a delay which needs to be imposed. This creates problems at the start and at the end of the sequence which must be dealt with. At the start we just keep outputting picture 0. At the end you will need to loop for longer to get all the pictures out. It's up to the calling function to do something with the decoded pictures as they come out -- write them to screen or to file, for example. . If coding is fast enough the compressed version could be watched real-time (with suitable buffering in the calling function to account for encode-time variations).<p>
NOTE: LoadNextFrame must be called atleast once before invoking this method.<p>
