No such element or plugin 'v4l2h264enc'

[Miguel Won]

Yes, I also tried with the device mapping:

pi at raspberrypi:~/Ubiquo/GSTREAMER/install $ docker run -it
--device=/dev/video0:/dev/video0 -v /opt/vc/:/opt/vc gst-base
root at 4e7f6736d7c4:/opt# cd gst-build/
root at 4e7f6736d7c4:/opt/gst-build# python3 gst-env.py
# gst-inspect-1.0 v4l2h264enc
No such element or plugin 'v4l2h264enc'

where "gst-base" is the name of the container. Does it need to be available
at the time of the building process? Not really sure how to do it.
