Right. Thanks for the comment.

I just verified that this bug is not an issue anymore and that it was a
consequence of bug 730078.

I verfied it by sending a sequence number a bit lower than the first packet in
RTP-Info
(gst-rtsp-server/rtsp-stream-transport.c::gst_rtsp_stream_transport_get_rtpinfo).
