 *  Skip this file if not doing video on the device.
 *
 *  The ccsdp_xxx api's provide a means to query and populate the SDP attributes
 *  for video m lines. These Api are not needed if we are not supporting video on
 *  the platform. For audio the stack will populate the appropriate attributes
 *
 *
 *  These API's can be invoked from the vcmCheckAttrs() and vcmPopulateAttrs()
 *  methods to populate or extract the value of specific attributes in the video SDP.
 *  These api require an handle to the SDP that is passed in the above methods.
 * <pre>
 * sdp_handle     The SDP handle
 * level       The level the attribute is defined.  Can be either
 *             SDP_SESSION_LEVEL or 0-n specifying a media line level.
 * inst_num    The instance number of the attribute.  Multiple instances
 *             of a particular attribute may exist at each level and so
 *             the inst_num determines the particular attribute at that
 *             level that should be accessed.  Note that this is the
 *             instance number of the specified type of attribute, not the
 *             overall attribute number at the level.  Also note that the
 *             instance number is 1-based.  For example:
 *             v=0
 *             o=mhandley 2890844526 2890842807 IN IP4 126.16.64.4
 *             s=SDP Seminar
 *             c=IN IP4 10.1.0.2
 *             t=0 0
 *             m=audio 1234 RTP/AVP 0 101 102
 *             a=foo 1
 *             a=foo 2
 *             a=bar 1   # This is instance 1 of attribute bar.
 *             a=foo 3   # This is instance 3 of attribute foo.
 * cap_num     Almost all of the attributes may be defined as X-cpar
 *             parameters (with the exception of X-sqn, X-cap, and X-cpar).
 *             If the cap_num is set to zero, then the attribute is not
 *             an X-cpar parameter attribute.  If the cap_num is any other
 *             value, it specifies the capability number that the X-cpar
 *             attribute is specified for.
 * </pre>
