This is likely related to
https://gitlab.freedesktop.org/gstreamer/gstreamer/issues/310 which I
worked around in the 1.14 branch (soon to be 1.14.4?) in that commit:
Could you try with the current 1.14 branch (the patch is not on master
because we want to solve the root issue in there).

> What happens is: The pipeline tries to move from READY to PAUSED but it cannot transition to PAUSED within the time that I allowed (30 seconds). I see plenty of warnings in the logs/*.log file which I have saved off. I wonder if those logs provide a clue about the problem that I'm facing. I also saved off the pipeline graphs in the logs folder (including SVG files).
