Description

Generic Forward Error Correction (FEC) decoder for Uneven Level Protection (ULP) as described in RFC 5109.

This element will work in combination with an upstream GstRtpStorage element and attempt to recover packets declared lost through custom 'GstRTPPacketLost' events, usually emitted by GstRtpJitterBuffer.

As such, this element cannot be usefully used from the command line, because a reference to the upstream storage object needs to be provided to it through its “storage” property, example programs are available at https://github.com/sdroege/gstreamer-rs/blob/master/examples/src/bin/rtpfecserver.rs and https://github.com/sdroege/gstreamer-rs/blob/master/examples/src/bin/rtpfecclient.rs.

Additionally, the payload types of the protection packets *must* be provided to this element via its “pt” property.

When using GstRtpBin, this element should be inserted through the “request-fec-decoder” signal.
