<p>Generic Forward Error Correction (FEC) decoder for Uneven Level
Protection (ULP) as described in RFC 5109.</p>
<p>This element will work in combination with an upstream <a class="link" href="gst-plugins-good-plugins-rtpstorage.html#GstRtpStorage"><span class="type">GstRtpStorage</span></a>
element and attempt to recover packets declared lost through custom
'GstRTPPacketLost' events, usually emitted by <a class="link" href="gst-plugins-good-plugins-rtpjitterbuffer.html#GstRtpJitterBuffer"><span class="type">GstRtpJitterBuffer</span></a>.</p>
<p>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 <a class="link" href="gst-plugins-good-plugins-rtpulpfecdec.html#GstRtpUlpFecDec--storage" title="The “storage” property"><span class="type">“storage”</span></a> property, example
programs are available at

<p>Additionally, the payload types of the protection packets *must* be
provided to this element via its <a class="link" href="gst-plugins-good-plugins-rtpulpfecdec.html#GstRtpUlpFecDec--pt" title="The “pt” property"><span class="type">“pt”</span></a> property.</p>
<p>When using <a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a>, this element should be inserted through the
<a class="link" href="gst-plugins-good-plugins-rtpbin.html#GstRtpBin-request-fec-decoder" title="The “request-fec-decoder” signal"><span class="type">“request-fec-decoder”</span></a> signal.</p>
