Hello,
Part of RTCP XR report is about discard/lost packets.
As I see, we report discard/lost events to RTCP XR module only in pjmedia_rtcp_rx_rtp2()
For example,
/* Report RTCP XR about packet losses */
for (i=seq_st.diff-1; i>0; --i) {
pjmedia_rtcp_xr_rx_rtp(&sess->xr_session, seq - i,
1, /* lost */
0, /* dup */
0, /* discard */
-1, /* jitter */
-1, 0); /* toh */
}
for (i=seq_st.diff-1; i>0; --i) {
pjmedia_rtcp_xr_rx_rtp(&sess->xr_session, seq - i,
1, /* lost */
0, /* dup */
0, /* discard */
-1, /* jitter */
-1, 0); /* toh */
}
But one more part of discard/lost statistics is collected inside jitter buffer in "pjmedia_jbuf" structure by updating the following fields:
struct
pjmedia_jbuf
{
...
unsigned jb_lost; /**< Number of lost frames. */
unsigned jb_discard; /**< Number of discarded frames. */
unsigned jb_discard; /**< Number of discarded frames. */
}
But I cannot find in code how this data is taken into account by RTCP XR module.
Am I missing something or it is a bug in
RTCP XR module?
Thanks,
Maxim
