76983d4454 gldisplay: add gst_gl_display_create_context
It also emits a create-context signal so that an application
can provide an external GstGLContext backend.

03908c679e gldisplay: synchronize the searching and creation of GstGLContext's
Ootherwise we could end up with multiple elements in different chains
each creating a context.  Fixes context creation with glvideomixer.

813fb633b4 gl: store the list of contexts within gldisplay
Removes the reliance on the allocation query to propogate GL contexts.

Allows thread safely getting a context for the a specific thread.

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.

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.

b85ffef956 [387/906] glmixer: add a glmixer base element
glmixer can be seen as a glfilter except it handles N requested
sink pads.
Each sink pad and the src pad are video/x-raw-gl.
glmixer is responsible for managing different framerates from inputs.
It uses OpenGL context sharing. It means that each input is in its
own OpenGL context shared together and shared with the OpenGL context
of the ouput gl chain.
Also add a glmosaic which is an example of implementation of glmixer.
For now glmosaic is a cube but it will be fixed in the next commits.
For now the glmixer has some weird behaviours in some configurations
but it will be improved in the next commits.
The autotools builds is temporarly broken since those changes
have been made on win32.

95dbe51fef [378/906] gldisplay: avoid to request gl thread when deleting a texture
A texture is not destroyed when when we are done with it.
This texture is just added to the texture pool in order to be
re-used. In this case no OpenGL code is executed so we do not need to
request gl thread.

2eb9cb551c [330/906] Can now share textures with an external gl context
The external opengl context must be specify when creating
our OpenGL context (glx) or just after (wgl).
When calling glXCreateContext or wglShareLists, the
external opengl context must not be current.
Then our gl context can be current in the gl thread while
the external gl context is current in an other thread.
