[meta-freescale] Qtwebkit and gstreamer on imx6 (yocto Sumo, QT5, framebuffer)

I am trying to play video in  qtwebkit using gstreamer 1.0. I can see
that gstreamer get called,  plugins is loaded, src and sink is setup
etc but then it just stops and  no video is showed in the browser. I
use the qt5 example browser to test  it. I build Sumo yocto without
wayland and x11. Is there anything  specific that needs to be done to
enable this combination? Video plays  as it should with
gst-play-1.0.We  use Congatec's Sumo branch, it is meta-freescale Sumo
branch (from July 2018) plus some minor changes for GPIO etc so I hope
it is ok that I send my question to this mailing

I'm not sure what the timed out at the end  means or how to figure out
what element/plugin is causing it. If anyone else has this working and
could save the same logs so I can compare that would be very much
appreciated. 0:00:10.851254563   3447  0x1711600 INFO
