            Bug ID: 797297
           Summary: glcontext: context is not being finalized if no
                    display is connected
    Classification: Platform
           Product: GStreamer
           Version: 1.14.x
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org

Created attachment 373948
  --> https://bugzilla.gnome.org/attachment.cgi?id=373948&action=edit
a simple python script which consequently creates pipelines, logs with and
without the issue

I use gl elements from gstreamer 1.14 with this [1] patch on a headless system
(linux 4.17, mesa 18.2).

It initializes and runs fine, but when I try to destroy the pipeline and build
a new one, old context persists, and newly created context is being created as
a software (llvmpipe) context (it seems due to the previous one is not
deleted).

Under wayland and X11 context is being finalized and (re)created fine. I've
attached a simple python script to test the issue, error log (from a headless
run) and a normal log (from under wayland)
