Can you check with 1.15.90 / git master if this problem is solved? Some
issues in that code were fixed after 1.15.2.

If it is still a problem, please create an issue here with all the
information you included in your mail already:
  https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/new

If possible, can you also include a simple testcase to reproduce the
problem? As simple as possible, the shm parts of the pipeline for
example shouldn't make any difference.


Thanks!
