GstGL.GLDisplay.prototype.new

function GstGL.GLDisplay.prototype.new(): {
    // javascript wrapper for 'gst_gl_display_new'
}

Since : 1.4

GstGL.GLDisplay.prototype.new_with_type

function GstGL.GLDisplay.prototype.new_with_type(type: GstGL.GLDisplayType): {
    // javascript wrapper for 'gst_gl_display_new_with_type'
}

Will always return a GstGL.GLDisplay of a single type. This differs from GstGL.GLDisplay.prototype.new and the seemingly equivalent call gst_gl_display_new_with_type (GST_GL_DISPLAY_TYPE_ANY) in that the latter may return NULL.

Since : 1.20

GstGL.GLDisplay.prototype.add_context

function GstGL.GLDisplay.prototype.add_context(context: GstGL.GLContext): {
    // javascript wrapper for 'gst_gl_display_add_context'
}

Since : 1.6

GstGL.GLDisplay.prototype.create_context

function GstGL.GLDisplay.prototype.create_context(other_context: GstGL.GLContext): {
    // javascript wrapper for 'gst_gl_display_create_context'
}

It requires the display's object lock to be held.

Since : 1.6

GstGL.GLDisplay.prototype.create_window

function GstGL.GLDisplay.prototype.create_window(): {
    // javascript wrapper for 'gst_gl_display_create_window'
}

GstGL.GLDisplay.prototype.ensure_context

function GstGL.GLDisplay.prototype.ensure_context(other_context: GstGL.GLContext, context: GstGL.GLContext): {
    // javascript wrapper for 'gst_gl_display_ensure_context'
}

Ensures that the display has a valid GL context for the current thread. If context already contains a valid context, this does nothing.

Since : 1.24

GstGL.GLDisplay.prototype.filter_gl_api

function GstGL.GLDisplay.prototype.filter_gl_api(gl_api: GstGL.GLAPI): {
    // javascript wrapper for 'gst_gl_display_filter_gl_api'
}

limit the use of OpenGL to the requested gl_api. This is intended to allow application and elements to request a specific set of OpenGL API's based on what they support. See GstGL.GLContext.prototype.get_gl_api for the retrieving the API supported by a GstGL.GLContext.

GstGL.GLDisplay.prototype.find_window

function GstGL.GLDisplay.prototype.find_window(data: Object, compare_func: GLib.CompareFunc): {
    // javascript wrapper for 'gst_gl_display_find_window'
}

Execute compare_func over the list of windows stored by display. The first argument to compare_func is the GstGL.GLWindow being checked and the second argument is data.

Since : 1.12

deprecated : 1.18: Use gst_gl_display_retrieve_window() instead.

GstGL.GLDisplay.prototype.get_gl_api

function GstGL.GLDisplay.prototype.get_gl_api(): {
    // javascript wrapper for 'gst_gl_display_get_gl_api'
}

see GstGL.GLDisplay.prototype.filter_gl_api for what the returned value represents

GstGL.GLDisplay.prototype.get_gl_api_unlocked

function GstGL.GLDisplay.prototype.get_gl_api_unlocked(): {
    // javascript wrapper for 'gst_gl_display_get_gl_api_unlocked'
}

GstGL.GLDisplay.prototype.get_gl_context_for_thread

function GstGL.GLDisplay.prototype.get_gl_context_for_thread(thread: GThread (not introspectable)): {
    // javascript wrapper for 'gst_gl_display_get_gl_context_for_thread'
}

Since : 1.6

GstGL.GLDisplay.prototype.get_handle

function GstGL.GLDisplay.prototype.get_handle(): {
    // javascript wrapper for 'gst_gl_display_get_handle'
}

Since : 1.4

GstGL.GLDisplay.prototype.get_handle_type

function GstGL.GLDisplay.prototype.get_handle_type(): {
    // javascript wrapper for 'gst_gl_display_get_handle_type'
}

Since : 1.4

GstGL.GLDisplay.prototype.remove_context

function GstGL.GLDisplay.prototype.remove_context(context: GstGL.GLContext): {

}

Must be called with the object lock held.

Since : 1.18

function GstGL.GLDisplay.prototype.retrieve_window(data: Object, compare_func: GLib.CompareFunc): {
    // javascript wrapper for 'gst_gl_display_retrieve_window'
}

Execute compare_func over the list of windows stored by display. The first argument to compare_func is the GstGL.GLWindow being checked and the second argument is data.

Since : 1.18

create-context

function create_context_callback(self: GstGL.GLDisplay, context: GstGL.GLContext, user_data: Object): {
    // javascript callback for the 'create-context' signal
}

Overrides the GstGLContext creation mechanism. It can be called in any thread and it is emitted with display's object lock held.
