glupload: not negotiating proper video format with videoconvert
This pipeline is failing to negotiate:
gst-launch-1.0 videotestsrc ! video/x-raw,format=I420 ! videoconvert ! glupload ! gtkglsink -v
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

glupload
should negotiate with videoconvert
to produce RGBA.
