Hi,

I'm having problems with jitterbuffer of rtsp. I think that sometimes a udp packet lost and I get the next error:


WARN      gstrtpjitterbuffer gstrtpjitterbuffer.c:1450:gst_rtp_jitter_buffer_chain:<rtpjitterbuffer654> Packet #56425 too late as #23657 was already popped, dropping
. . . .
WARN      gstrtpjitterbuffer gstrtpjitterbuffer.c:1450:gst_rtp_jitter_buffer_chain:<rtpjitterbuffer654> Packet #65535 too late as #23657 was already popped, dropping
WARN      gstrtpjitterbuffer gstrtpjitterbuffer.c:1450:gst_rtp_jitter_buffer_chain:<rtpjitterbuffer654> Packet #0 too late as #23657 was already popped, dropping
......
WARN      gstrtpjitterbuffer gstrtpjitterbuffer.c:1450:gst_rtp_jitter_buffer_chain:<rtpjitterbuffer654> Packet #23656 too late as #23657 was already popped, dropping
WARN      gstrtpjitterbuffer gstrtpjitterbuffer.c:1450:gst_rtp_jitter_buffer_chain:<rtpjitterbuffer654> Packet #23657 too late as #23657 was already popped, dropping

Until the packet number is the same that first that fail. Then I get next error for every packet received:

WARN         rtpjitterbuffer rtpjitterbuffer.c:711:rtp_jitter_buffer_insert: duplicate packet 23658 found

Questions:

Is this a bug?

How I can detect this problem from my app?

Regards
