Combining #GST_MAP_GL with #GST_MAP_WRITE has the same semantics as though you are writing to OpenGL. Conversely, combining #GST_MAP_GL with #GST_MAP_READ has the same semantics as though you are reading from OpenGL.

Initializes the GL Base Memory allocator. It is safe to call this function multiple times. This must be called before any other GstGLBaseMemory operation.
Initializes the GL Buffer allocator. It is safe to call this function multiple times. This must be called before any other #GstGLBuffer operation.
Perform the steps necessary for retrieving a #GstGLDisplay and (optionally) an application provided #GstGLContext from the surrounding elements or from the application using the #GstContext mechanism.
If the contents of display_ptr or other_context_ptr are not %NULL, then no
#GstContext query is necessary for #GstGLDisplay or #GstGLContext retrieval
or is performed.
This performs #GstContext queries (if necessary) for a winsys display connection with %GST_GL_DISPLAY_CONTEXT_TYPE, "gst.x11.display.handle", and "GstWaylandDisplayHandleContextType" stopping after the first successful retrieval.
This also performs a #GstContext query (if necessary) for an optional application provided #GstGLContext using the name "gst.gl.app_context". The returned #GstGLContext will be shared with a GStreamer created OpenGL context.

Retrieves the stored 4x4 affine transformation matrix stored in meta in
NDC coordinates. if meta is NULL, an identity matrix is returned.

See gst_gl_value_set_texture_target_from_mask() for what entails a mask
an initialized #GValue of type G_TYPE_STRING
A mask is a bitwise OR of (1 << target) where target is a valid #GstGLTextureTarget
an uninitialized #GValue
a bitwise mask of #GstGLTextureTarget's
Note: this function first searches the first 1 kilobytes for a #version
preprocessor directive and then executes gst_glsl_version_profile_from_string().

Note: this function expects either a #version GLSL preprocesser directive
or a valid GLSL version and/or profile.
a valid GLSL #version string
An option that can be activated on bufferpools to request OpenGL synchronization metadata on buffers from the pool.
