I also insist on changing the name of this element since it really IS
NOT a jitter buffer :) it's a queuing, reordering, dropping, timestamp
setting buffer.
Ok, we discussed this more at #farsight, and the consensus was that
playout would be better name than jitter. But we also talked some more
about what jitter really means:
- jitter = variation in packet transit time
- types of jitter
- slow increase/decrease (drift), usually caused by clocking
- stepwise changes, caused by events in network nodes and links
- big spikes, routing changes, node/link failures, congestion
- interarrival jitter = term defined in rfc3550
- statistical variance of packet interarrival time
So essentially the gst rtp buffer element really is a jitter buffer. It
has to do queing, reordering, and xrun/drift detection to handle all the
different types of jitter.
