RTP retransmission mechanism in gstreamer 1.2.0

[abhilash]

Hi,

I tried the pipelines from my last post. I am able to see the
retransmissions. But now I'm facing the following problems:(As per my
understanding I tried to set some options. Please correct me if I'm wrong.)

1) In some cases receiver sends more than 1 retransmission requests to
sender for single packet lost.
For this, I tried increasing the DEFAULT_RTX_DELAY to 50 at receiver side
but, still multiple retransmission requests are there.

2) Sometimes even if the sender had retransmitted the packet I see
retransmission requests from receiver to sender.

3) For some packet receiver sends retransmission requests & sender did not
retransmit the required packet. As if it does not have that particular
packet available in its rtprtxqueue. For this, I tried increasing
DEFAULT_MAX_SIZE_PACKETS at the sender side.

4) I am hearing audio glitches. For this, I tried increasing the latency
property of rtpbin at receiver side but, still the glitches are there after
some time.

   Are there any other options to be set properly to minimize/remove above
errors?
 
Thanks,
Abhilash
