rtpfec example causes h264 artifacts with FEC overhead > 0 and netsim = 0
Created by: alexagv
When changing the vp8enc to x264enc and rtpvp8pay to rtph264pay the FEC overhead causes artifacts on receiving stream despite netsim = 0 (no network loss). Tried with multiple bitrates and GOP lengths. When FEC = 0 everything is fine, but from 1 to 100, artifacts appear
Tested on: macOS High Sierra and Ubuntu 18.04, both running gstreamer 1.14.4
