<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/gl/gstglcontext.c">#GstGLContext wraps an OpenGL context object in a uniform API. As a result
of the limitation on OpenGL context, this object is not thread safe unless
specified and must only be activated in a single thread.
Environment variables:
- `GST_GL_API`: select which OpenGL API to create and OpenGL context for.
Depending on the platform, the available values are
'opengl', 'opengl3' (core profile), and 'gles2'. See the
the #GstGLAPI enumeration for more details.
- `GST_GL_PLATFORM`: select which OpenGL platform to create an OpenGL
context with. Depending on the platform and the
dependencies available build-time, the available values
are, 'glx', 'egl', 'cgl', 'wgl', and 'eagl'
- `GST_GL_CONFIG`: select the configuration used for creating the OpenGL
context and OpenGL surface. Written out as a GstStructure
that has been serialized to string. e.g.
`GST_GL_CONFIG="gst-gl-context-config,red-size=8,green-size=8,blue-size=8,alpha-size=8,depth-size=16"`.
Not all platforms will support the same level of
functionality.</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/gl/gstgldisplay.c">#GstGLDisplay represents a connection to the underlying windowing system.
Elements are required to make use of #GstContext to share and propagate
a #GstGLDisplay.
There are a number of environment variables that influence the choice of
platform and window system specific functionality.
- GST_GL_WINDOW influences the window system to use. Common values are
'x11', 'wayland', 'win32' or 'cocoa'.
- GST_GL_PLATFORM influences the OpenGL platform to use. Common values are
'egl', 'glx', 'wgl' or 'cgl'.
- GST_GL_API influences the OpenGL API requested by the OpenGL platform.
Common values are 'opengl', 'opengl3' and 'gles2'.
&gt; Certain window systems require a special function to be called to
&gt; initialize threading support. As this GStreamer GL library does not preclude
&gt; concurrent access to the windowing system, it is strongly advised that
&gt; applications ensure that threading support has been initialized before any
&gt; other toolkit/library functionality is accessed. Failure to do so could
&gt; result in sudden application abortion during execution. The most notably
&gt; example of such a function is X11's XInitThreads\().</doc>

If @respecify is %TRUE, then the copy is performed in terms of the texture

vice versa. The requirement for this to succeed is that the backing texture
data must be the same size, i.e. say a RGBA8 texture is converted into a RG8
texture, then the RG texture must have twice as many pixels available for
output as the RGBA texture.
Otherwise, if @respecify is %FALSE, then the copy is performed per texel
using glCopyTexImage. See the OpenGL specification for details on the
mappings between texture formats.</doc>

access a texture such that accessing a texel from a texture through the swizzle
index produces values in the order (R, G, B, A) or (Y, U, V, A).
For multi-planer formats, the swizzle index uses the same component order (RGBA/YUVA)
and should be applied after combining multiple planes into a single rgba/yuva value.
e.g. sampling from a NV12 format would have Y from one texture and UV from
another texture into a (Y, U, V) value. Add an Aplha component and then
perform swizzling. Sampling from NV21 would produce (Y, V, U) which is then
swizzled to (Y, U, V).</doc>
