GST_PIPELINE grammar.y:816:priv_gst_parse_yyparse: no element "x264enc" #12

I install this node on ubuntu 18.04 with melodic. When I use VLC to connect to the rtsp server, this node prints the following error:

The issue can be solved by sudo apt install gstreamer1.0-libav gstreamer1.0-plugins-ugly

Also, When I check the stream like this:

gst-launch-1.0 -v rtspsrc location=rtsp://127.0.0.1:8554/back drop-on-latency=true use-pipeline-clock=true do-retransmission=false latency=0 protocols=GST_RTSP_LOWER_TRANS_UDP ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink sync=true

I get:

WARNING: erroneous pipeline: no element "h264parse"

Solve it by: sudo apt install gstreamer1.0-plugins-bad

Thankyou @armme41. I've updated the readme to include the dependency. Better late than never!
