rtpstorage
Helper element for storing packets to aid later packet recovery from packet loss using RED/FEC (Forward Error Correction).
The purpose of this element is to store a moving window of packets which downstream elements such as can request in order to perform recovery of lost packets upon receiving custom GstRtpPacketLost events, usually from .
As such, when building a pipeline manually, it should have the form:
rtpstorage ! rtpjitterbuffer ! rtpulpfecdec
where rtpulpfecdec get passed a reference to the object pointed to by the property.
The property should be configured with a value
equal to the latency, plus some tolerance, in the order
of milliseconds, for example in the example found at
https://github.com/sdroege/gstreamer-rs/blob/master/examples/src/bin/rtpfecclient.rs,
size-time is configured as 200 + 50 milliseconds (latency + tolerance).
When using , a storage element is created automatically, and can be configured upon receiving the signal.
