Class Methods

gst_gl_mixer_class_add_rgba_pad_templates 

gst_gl_mixer_class_add_rgba_pad_templates (GstGLMixerClass * klass)

Adds the default RGBA pad templates to this class. If you have any special template requirements like a different pad subclass or different supported caps, you should not call this function and add the pad templates yourself manually.

Parameters:

klass –

the GstGLMixerClass

Since : 1.24

GstGL.GLMixerClass.prototype.add_rgba_pad_templates 

function GstGL.GLMixerClass.prototype.add_rgba_pad_templates(klass: GstGL.GLMixerClass): {
    // javascript wrapper for 'gst_gl_mixer_class_add_rgba_pad_templates'
}

Adds the default RGBA pad templates to this class. If you have any special template requirements like a different pad subclass or different supported caps, you should not call this function and add the pad templates yourself manually.

Parameters:

klass (GstGL.GLMixerClass) –

the GstGL.GLMixerClass

Since : 1.24
