Matthew Waters af493eb6b2 gldisplay: add a list of glwindow's 
With the event thread on the display, for a particular winsys event
we need to be able to retreive the window that the event matches.

Matthew Waters 9bafa08a5d gl/docs: massive update 
- add Since: markers where necessary.
- document structs
- add documentation headers for each module (short_description,
  see_also, etc)
- reduce the number of warnings gtk-doc outputs
- fix spelling mistakes

Matthew Waters db51c90d5d glcontext: correct precondition for get_gl_version 
The intention was to assert if both maj and min were NULL (as there would be no
point calling the function).  Instead if either maj or min were NULL, the assert
would occur.

Fix that.

Matthew Waters 4a6b20cc42 glcontext: fix get_current_gl_api() on win32 
Another case of incorrect calling conventions.

Using this function on win32 would corrupt the stack pointer and end in
massive hilarity.

Matthew Waters 97e66be37d gl: add support for building against GLES3 headers 
with a fallback to GLES2 headers if available.

Matthew Waters 5f87cc0b65 glcontext: add a method to add a context to another share group 
Intended for use with wrapped contexts that are created shared with gst's
gl contexts in order to manage the internal sharegroup state correctly.

e.g. with caopengllayer (which is used in glimagesink and caopengllayersink
on OS X), we create a CGL context from the gst context and the sharing state
was not being correctly set on either GL context and gst_gl_context_is_shared()
was always returning FALSE.

With 11fb4fff80 only flushing with multiple
shared contexts, the required flush was not occuring causing screen
corruption or stuttering.

Note: this didn't affect GST_GL_API=opengl pipelines

Matthew Waters 7dcdb1d29c glcontext: don't enable GL debug for messages that won't be logged 
This is an optimization to avoid pointless string processing.
 2017-12-09 19:32:16 +00:00
Alessandro Decina 7e1a42ce55 gstglcontext: micro optimization to gst_gl_context_thread_add 
Invoke the callback right away when called on the context thread. Removes
overhead when nesting libgstgl calls (for example when working with the sync
meta).

Matthew Waters 472970324c glcontext: implement checking whether a context has been shared 
Some operations are unnecessary when running with only a single GL
context.
e.g. glFlush when setting a fence object as the flush happens on wait.

API: gst_gl_context_is_shared

Sebastian Dröge 039865fc03 glcontext: Signal context creation from inside the context loop and use g_thread_join() instead of a custom condition variable 
Also protect against spurious condition variable wakeups during context
creation.

Matthew Waters 764c4a33bc gl: fix usage of string.h and stdio.h functions without including the headers

Justin Kim c8628fc43d glcontext: add specific error message when missing GL_SHADING_LANGUAGE_VERSION 
GL_SHADING_LANGUAGE_VERSION was introduced since ES 2.0, but in some
android emulator doesn't support this feature. To prevent confusion for
developer, the error message need to be more clear.

Matthew Waters 9587eb477d glcontext: pass display to implentation's _new() 
This allows the context to fail creation based on incompatible
display type's. e.g. glx context with an wayland display handle.

Matthew Waters 66407b9877 glcontext: fix get_current_gl_api on x11/nvidia drivers 
They require to get_proc_address some functions through the
platform specific {glX,egl}GetProcAddress rather than the default
GL library symbol lookup.
 2017-12-09 19:32:05 +00:00
Matthew Waters cfa9b94045 glcontext: consolidate get_proc_address function definition 
Pass the GstGLAPI directly.

Matthew Waters 78957c45c2 glcontext: track sharedness with a cookie 
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.
