+* 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.
