Detailed Description

Contains classes vidl_vil1_mpegcodec_data and vidl_vil1_mpegcodec_helper.

This is a rewrite of the mpeg2dec program. it has been modified to work with the video player, i.e., by implementing a get_section method. this required some buffering, and the ability to decode a file grab at a time. there is some extra legacy code here. though some things seem to serve no purpose, i left them there as hooks for possible evolution of this class.

the mpeg_codec sends a request to this helper via a decode_request. data is stored in the mpeg_codec_data class, which holds a frame buffer, owned by the mpeg_codec. decoded frames are stored in this frame_buffer, and subsequent user requests for frames just does a memcpy from this frame_buffer into the user supplied buffer.
