It's nothing more than
gst-launch-1.0 -v v4l2src ! <any needed conversions> ! xvimagesink
in my case, the conversions are bayer2rgbneon. However, this only shows
you the frame rate negotiated on the pads (which is actually good enough
to show the issue.)
How I stumbled across though this was when I was trying to encode:
gst-launch-1.0 v4l2src device=/dev/video9 ! bayer2rgbneon ! \
videoconvert ! x264enc speed-preset=1 ! avimux ! \
filesink location=test.avi
I noticed that vlc would always say it was playing the resulting AVI
at 30fps.
