Description Aleix Conchillo Flaqué 2012-08-22 23:34:35 UTC
In some cases the default probation for RTP packets does not work. For example,  a JPEG RTP stream every 4 seconds with a network latency of 150ms and a 10ms jitter always fails the probation check (may be it would work if we wait for a long time, which make it useless). This is because non of the packets received have consecutive sequence numbers (because of the jitter) and also because we might sent a few packets for the JPEG (and every few seconds).

make rtp packet probation configurable

This is an initial proposal to make the RTP probation configurable. A value of 0 disables the probation which can be useful in some cases.

This is not totally true as it works sometimes, depending if in the 4 seconds packet set we get consecutive packets. However the problem remains as sometimes we might never get consecutive packets.
