* Description:  Header file for video codec class

*                Codec variation is handled through this class: MPEG-4 video 

*                can be supported only if feature flag __MPEG4_VIDEO_ENCODING

*                is defined. Most of the MPEG-4 code is embedded, but the current

*                controller allows to set MPEG-4 iff GetSupportedVideoCodecsL

*                returns MPEG-4 codec as one of the supported codecs.

*                There are two implementations for this class, one that checks 

*                DevVideoRecord for basic codecs (H.263 only), and another one

*                that checks H.263 and MPEG-4. The basic one is used if the MPEG4

*                feature flag is not defined.
