e762f1b376 Revert "gstgldisplay: Add public foreign_display property"
This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.

The underlying problem needed to be solved in a different way.  See
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/640
for more details.

This reverts commit 2e686b0dad.

4c008895ce gldisplay: add support removing a context from the internal list 2020-03-03 02:11:52 +00:00

3b552cc05a display: add a specific lock for the list of windows
It's either this or replacing all the object lock usage in gldisplay
with a recursive mutex which is not backwards compatible

The failure case is effectively:
1. The user has locked the display object lock
2. a glcontext loses it's last ref and attempts to quit the window
3. gst_gl_window_quit() attempts to remove the window from the display
4. gst_gl_display_remove_window attempts to take the display object lock

The only concern with changing the locking for the window list in the
display is that gst_gl_display_create_window() has documentation requiring
the object lock to be held which must continue to work correctly.

d79d742492 gl/display: Add thread-safe retrieve_window
Returning a transfer none value for a value checked by a lock is not
thread safe as the reference could disappear before the caller can take
its reference.

5f70adf667 gl/egl/display: Add support EGLDevice display type
Simple addition for supporting EXT_platform_device typed display.
It's a kind of special display type (part of EGL specification)
which has no window at all.
To use EGLDevice explicitly, set environment "GST_GL_WINDOW=egl-device"

2e686b0dad gstgldisplay: Add public foreign_display property
We use this property in gst_gl_display_egl_from_gl_display, to set
foreign_display for the new GstGLDisplayEGL instance. This fixes a
problem where gst_gl_display_egl_finalize calls EglTerminate on a
pre-existing EGL connection.

c5b5ef16d3 gl: GST_EXPORT -> GST_GL_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

4952fdd956 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

303b77eeff [890/906] x11: add display subclass
GstGLDisplayX11 holds the display connection and name.  Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads().  Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.

The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl).  In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.
