Responding to Nicolas Dufresne:

Using this pipeline with caps filter, I still couldn't get the device to
start streaming:
gst-launch-1.0 -v v4l2src device=/dev/video3 !
video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! v4l2h264enc
extra-controls="controls,h264_profile=4,video_bitrate=20000
00;" ! video/x-h264,profile=main,level=4 ! h264parse ! rtspclientsink
location=rtsp://<wowza-address-stripped>:1935

>Can you file a bug about this one please, bugs.gnome.org. 
Sure, I'll start this soon. Would you like me to reference the URL from
bugzilla here when I have filed one?

>This one is familiar, but I thought it was fixed in 4.15+ (or latest 4.9
from linaro). Which kernel are you running?
I am running a fork of the linaro 4.14.15 kernel. My github repo for it is
located here, if you are interested in taking a look:
