c2471aec81 gl: add EGLImage support 
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

894035f0d7 gl: Add EGLDisplay display subclass 2017-12-09 19:31:34 +00:00
Matthew Waters
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.

e80533dcee [793/906] add a GstGLContext object that will be the basis of OpenGL contexts 
At the moment it just sits in between GstGLDisplay and GstGLWindow
performing some of the stuff that GstGLWindow used to do.

d17a4381b1 [732/906] build: fix repeated typedefs 
Write forward declarations in another way to avoid
repeated typedefs "error: redefinition of typedef".
Raised when using i686-apple-darwin11-llvm-gcc-4.2
It seems that C apple compiler does not support
C11 feature.

db236c510f [633/906] display: fail properly in context creation in order to minimize a race condition 
previously, on context creation, when we failed to get a valid context
we would still atempt to run the window mainloop as well as setting an error
on the display. This would cause the calling element to finalize the display
and therefore attempt to quit the window mainloop.  However the mainloop
may not have started running.  Thus when the window mainloop ran it would
never a get a quit message and never end.
