gst-launch-1.0 does not accept the pipeline as is because of the comma.
Which pipeline did you use?

This looks like it could be a problem with libx264 on your system. Try
also with only the video part of the pipeline (without qtmux and going
to a fakesink), with videotestsrc instead of v4l2src, etc.

And running in valgrind is probably also a good idea.
