| class CCompressedVideoFormat : public CBase |
Defines a compressed video format. The format is identified by its MIME type, which may include parameters that describe the used format profile and level. The MIME type used for H.263 is video/H263-2000, specified in TS 26.234, and the type for MPEG-4 is video/MP4V-ES, specified in RFC 3016.
