Table 2-1 The option Values
DescriptionValue
Obtains the Synchronization Source
(SSRC) identifier.
RTP_GSSRC (uint32_t *ssrc)
Obtains the current count of members.
RTP_GMEMCOUNT (uint32_t *ssrc)
Obtains the current list of members.
RTP_GMEMLIST (char *buf, int buflen)
Sets an address to which the RTP/RTCP
packets need to be sent.
RTP_SSENDTOADDR
RTCP_SSENDTOADDR (struct sockaddr *)
Obtains the current count of addresses
to which RTP/RTCP packets are sent.
RTP_GSENDTOADDRNUM
RTCP_GSENDTOADDRNUM (unit64_t *cnt)
Obtains the current list of addresses to
which RTP/RTCP packets are sent.
RTP_GSENDTOADDRLIST
RTCP_GSENDTOADDRLIST (char *buf, int
buflen)
Sets the values for Source Description
(SDES) items for the RTP session
descriptor.
RTCP_SSDES (rtcp_sdes_item_t *item)
Obtains the values for SDES items for
the RTP session descriptor.
RTCP_GSDES (rtcp_sdes_item_t *item)
Set the sampling rate for the media
carried in the RTP packets, which are
received on the RTP session descriptor.
The jitter calculations will be correct
only if the RTCP_STIMESTAMPRATE
option is set.
RTCP_STIMESTAMPRATE (struct rtp_ioctsrate
*srate)
Get the sampling rate for the media
carried in the RTP packets, which are
received on the RTP session descriptor.
The value set using the
RTCP_STIMESTAMPRATE ioctl is
retrieved.
RTCP_GTIMESTAMPRATE (struct rtp_ioctsrate
*srate)
