This allows consumers of the gstgl dependency where gstgl is optional
to do things like:
config_data.set('HAVE_GST_GL', gstgl_dep.found())
deps = [gstvideo_dep, gstgl_dep]
meaning they can still use the dep unconditionally. With the
disabler we would just disable the whole target even if the
gstgl part was an optional extra. We can add an option to
dependency() later to let users/consumers of the dep decide
if they want a not-found dependency or a disabler instead.
It's also needed by the generic/states test and the variable
is currently checked as part of the opengl lib tests so wouldn't
be available if opengl was disabled.
Building an image with yocto for an 'am335x' processor will fail,
because 'gbm.h' can not be found and 'EGL_PLATFORM_GBM_MESA' is not defined.
So simply adding define of 'EGL_PLATFORM_GBM_MESA' in 'gstgldisplay_egl.c'
and adding 'GBM_CFLAGS' in 'gst-gl.m4' to get rid of this errors and complete
a full build process.

This was miss-leading VAAPI which was not forcing linear back buffers,
would still export DMABuf. That caused bad rendering as the buffers are
tiled and most likely compressed.

e4bf9ed8f0 was not quite right and changed
the wrong thing. Intead we needed to change the multiplication order
and should have kept the previous to/from matrices as is done in this
patch.
We would make the subproject conditional on the wrap-mode=nodownload
however get_option('wrap-mode') or similar is not available from
meson.build files as the wrap-mode is meant to be used automatically.
Instead use the dependency fallback mechanism to get at the subproject
where possible i.e. when downloading is allows and only add the compat
includes when we have a valid internal dependency from the gl-headers
subproject.

This reverts commit 82c43ff9a3.
Reverting for the time being, since it trips up build bots
that don't have network connectivity.
We ideally shouldn't have a subproject that's used unconditionally.
The matrices were converting the wrong values with non-diagonal-only matrices.
e.g. a typical yflip matrix in [-1,1]^3 such as
1 0 0 0
0 -1 0 0
0 0 1 0
0 0 0 1
Would have actually required a matrix like this in [0,1]^3
1 0 0 0
0 -1 0 0
0 0 1 0
0 -2 0 1
Which is
1. not consistent with our multiplication convention and would require
transposing matrices or changing our multiplication order (from what is
generally used on opengl matrix guides/tutorials).
2. Produces incorrect values when input with actual vertices accounting for
the difference in multiplication order. e.g. some vertices multiplied by
the yflip matrix using vertex * yflip(== transpose(yflip) * vertex):
vertex: -> result: expected:
vec4(1,0,1,1) -> vec4(1,-2,1,1) vec4(1,1,1,1)
vec4(1,1,1,1) -> vec4(1,-3,1,1) vec4(1,0,1,1)
With the updated values, we now get the expected values.
Includes a test for this behaviour and the example above
For a single format in the caps, we were returning some weird answers,
like only RGB formats for a RGB input when we can also support YUV from
RGB.
Fixup of 3cfff727b1 where I thought my
previous (~6month) self had got this right. Don't trust your previous
self people!
Also yield common options to the outer project (gst-build in our case)
so that they don't have to be set manually and use array types for some
options.
Instead of having special cases at each GL texture creation, upload,
readback or copy for all non-8-bits-per-components.
Simply store the more specific format and retrieve the generic
component/type tuple from that.
Introduce a helper function for retrieving the generic GL format (RGBA,
RGB, RG, R, L, A) and type (BYTE, SHORT, SHORT_5_6_5) from a sized
GL format enum (RGBA8, RGB565, RG8, etc).
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.
Allow for sub-classes to change pad templates to
support other texture targets, and bind input textures
accordingly.
When setting the caps, also store the texture target.
By default, glfilter only reports 2D texture targets
in the default caps, but sub-classes can change that
and it would be nice if they could easily find out
which texture targets were negotiated.
This adds 2 fields to the public struct, but since
it's unreleased -base API, it's not an ABI break.
This prevents cross compilation errors like:
usr/include/xf86drm.h:40:10: fatal error: drm.h: No such file or directory
These are caused because gstgldisplay_gbm.h includes xf86drm.h .

When trying to create a wayland display, it may fail because there
is not actually display to connect. It this case NULL is returned
but the created instance is not freed.
This patch unrefs the failed display.

We can pass string constants here to g_strdup_printf(),
so do so and re-enable the -Wformat-nonliteral warning
we had to disable when merging the opengl libs.
Tests and documentation will follow separately.
The mixer elements in the opengl plugin need to stay
in -bad for now since they use GstVideoAggregator.

As most Wayland compositors supports XWayland, X11 backend get
selected. This also realign better GStreamer decision to what
happens with GTK and other stack out there.
This patch adds code to gldownload to export the image as a
dmabuf if requested. The element now exposes memory:DMABuf as
a cap feature, and if it is selected, the element exports the
texture to an EGL image and then a dmabuf. It also implements a
fallback to system memory download in case the exportation failed.

Undefined symbols for architecture x86_64:

Might need some more in other headers, but first need to
clarify what exactly should be exported, there are some
inconsistencies (installed header files vs. funcs in docs).
It causes crashes in applications because the result of
fbGetDisplay() might be in use elsewhere in the application
and Vivante doesn't seem to do any refcounting
This reverts commit 47fd4d391e.
This patch is incorrect. It doesn't actually compile, and causes a crash
because the viv-fb window implementation needs a native EGL handle
to pass to fbCreateWindow, but the GstGLDisplayEGL handleis actually
an EGLDisplay now (and gets cast to the wrong type)
This simplifies the code a lot without any functional changes apart from
not closing the display connection. Closing the display connection is
not safe to do as it is shared between all other code in the same
process and no reference counting or anything happens at the platform
layer.
1. Propagate the GstGLDisplay we create
2. Add the created GstGLContext to the propagated GstGLDisplay
Otherwise with multi-branch GL pipelines involving gtkglsink, things
will fall apart and errors will be genarated somewhere.
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

Make a bunch of symbols private that are currently leaked
accidentally because they have a gst_* prefix and are used
internally. We mark those we can't make static with
G_GNUC_INTERNAL so that they get hidden with the autotools
build as well (although we could just pass -fvisibility=hidden
there too).
Found on rpi when gpu_mem is too low so there is not enough memory to
create the eglimage. But still gst_buffer_pool_acquire_buffer succeeded.
And it leads to a CRITICAL assert:
gst_egl_image_get_image: assertion 'GST_IS_EGL_IMAGE (image)' failed

Avoids dereferencing dead objects
What happens in the autovideosink case is that context 1 is created and
destroyed before all the async operations hae executed on the associated
window. When the delayed operations execute, they then reference dead
objects and crash.
We fix this by keeping refs over all async operations so the object
cannot be deleted while async operations are in flight.

Add a function to install the default RGBA pad templates,
but don't make them required so that there can be
GstGLFilter sub-classes with different input/output
caps if they want. Remove the hard-coded RGBA restriction in
the set_caps_features call, as it will be taken care
of by intersecting with the pad templates.
Update all the sub-classes to match
On the raspberry pi no pkg-config file is provided for the bcm_host
library. We are using AC_CHECK_LIB to detect this lib with autotools,

We have to pass the "height" as height = vmeta->offset[1] / width to the
API, which of course does not work well for formats with only a single
plane. Use the whole memory size instead of the offset in that case.
GL_RGB565 is sized internal glformat, the corresponding glformat
should be GL_RGB and type is GL_UNSIGNED_SHORT_565. Otherwise will
return GL_INVALID_ENUM when creating texture.

With the macOS/iOS implementations, the active thread can change
multiple times over the life of a pipeline which would expose a race in

meson's configure_file emits only a comment like /* #undef ... */
for values which are unset in the configuration_data. For
gstglconfig.h, this differs from the autotools build where the
preprocessor definitions are always either 0 or 1. So loop over a
list of variables to set to zero as default.
Also sync up the gstglconfig.h.meson file with the additional
macros defined by the autotools build.

Windows aren't always removed in time, and it turns out to be

All code interacting with Objective-C objects should now use Automated
Reference Counting rather than manual memory management or Garbage
Collection. Because ARC prohibits C-structs from containing
references to Objective-C objects, all such fields are now typed
'gpointer'. Setting and gettings Objective-C fields on such a
struct now uses explicit __bridge_* calls to tell ARC about
object lifetimes.

Calling g_main_context_push_thread and then g_main_context_invoke()
(used by gst_gl_window_send_message_async()) in the same thread will
cause the invoked function to run immediately instead of being delayed.
This had implications for the creation of the OpenGL context not waiting
until the main loop had completely started up and as a result would
sometimes deadlock in short create/destroy scenarios.

- xcb is supposedly thread-safe!
videotestsrc ! glimagesink now doesn't spuriously result in a
'call XInitThreads()' error however if anybody else is using X11,
then XInitThreads() still needs to be called and multiple glimagesink's
still need XInitThreads().
Everything still takes libX11 handles as they are compatible with the xcb
variants. Unfortunately we cannot move fully over to xcb due to GLX being
entirely based on Xlib. It's also impossible to transform a xcb_connection
to a Display which means we require X11 handles.
