SOLUTION:

update Gstreamer

It seems I only have gstreamer0.10.

Reading package lists... Done
Building dependency tree       
Reading state information... Done
gstreamer0.10-tools is already the newest version.
libgstreamer0.10-0 is already the newest version.
libgstreamer0.10-dev is already the newest version.
gstreamer0.10-ffmpeg is already the newest version.
gstreamer0.10-plugins-ugly is already the newest version.
gstreamer0.10-plugins-base is already the newest version.
gstreamer0.10-plugins-good is already the newest version.
libgstreamer-plugins-base0.10-dev is already the newest version.
gstreamer0.10-plugins-bad is already the newest version.

Installing libgstreamer-plugins-base1.0-dev fixed things for me.

Grate same here!

Nice. It helps :)

Installing libgstreamer-plugins-base1.0-dev fixed things for me.

Thank you so much!

Thank you so much

ubuntu 16.04, opencv3.4.4 installation also needs this, thanks for the fix.
