- Add a videoconvert element before the videosink so that the output
works no matter what format gets negotiated (A444_16LE for me)
- Specify a reasonable video format and size with a capsfilter, so
we don't default to something silly like A444_16LE @ 240p.
- Add a timeoverlay element, so it's obvious when stoppping/restarting
the pipeline that the input stream is just picked up again from the
moment the consumer pipeline is restarted.
