[−][src]Struct gstreamer_gl::GLContext
GLContext 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.

GLContextExt, gst::ObjectExt, glib::object::ObjectExt, GLContextExtManual
Implementations
impl GLContext[src]
pub fn new<P: IsA<GLDisplay>>(display: &P) -> GLContext[src]
pub fn get_current() -> Option<GLContext>[src]
pub fn get_current_gl_api(platform: GLPlatform) -> (GLAPI, u32, u32)[src]
impl GLContext[src]
pub unsafe fn new_wrapped<T: IsA<GLDisplay>>(
display: &T,
handle: uintptr_t,
context_type: GLPlatform,
available_apis: GLAPI
) -> Option<GLContext>[src]
display: &T,
handle: uintptr_t,
context_type: GLPlatform,
available_apis: GLAPI
) -> Option<GLContext>
Wraps an existing OpenGL context into a GLContext.
Note: The caller is responsible for ensuring that the OpenGL context
represented by handle stays alive while the returned GLContext is
active.
context_type must not be GLPlatform::None or GLPlatform::Any
available_apis must not be GLAPI::None or GLAPI::Any
display
a GLDisplay
handle
the OpenGL context to wrap
context_type
a GLPlatform specifying the type of context in handle
available_apis
a GLAPI containing the available OpenGL apis in handle
Returns
a GLContext wrapping handle
pub fn get_current_gl_context(context_type: GLPlatform) -> uintptr_t[src]
context_type
a GLPlatform specifying the type of context to retrieve
Returns
The OpenGL context handle current in the calling thread or None
pub fn get_proc_address_with_platform(
context_type: GLPlatform,
gl_api: GLAPI,
name: &str
) -> uintptr_t[src]
context_type: GLPlatform,
gl_api: GLAPI,
name: &str
) -> uintptr_t
Attempts to use the context_type specific GetProcAddress implementations
to retrieve name.
See also GLContext::get_proc_address.
context_type
a GLPlatform
gl_api
a GLAPI
name
the name of the function to retrieve
Returns
a function pointer for name, or None
