I am running following command but it is just showing warning.

sudo gst-launch-1.0 -e v4l2src device=/dev/video13 num-buffers=2000 ! autovideoconvert format=i420 width=1920 height=1080 framerate=30/1 ! vaapih264enc rate-control=cbr tune=high-compression ! qtmux ! filesink location=encoded_video.mp4

I got mine to work using the following command:
sudo gst-launch-1.0 -e rtsp location=rtsp://192.168.8.1:8554/video13 ! rtph264depay ! h264parse ! mp4mux ! filesink location=video.mp4

In this case, I am getting
