Class Details

class GstGL.GLMixer(**kwargs)

Bases:

GstGL.GLBaseMixer

Abstract:

Yes

Structure:

GstGL.GLMixerClass

GstGL.GLMixer helps implement an element that operates on RGBA textures.

New in version 1.24.

classmethod 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.

New in version 1.24.

get_framebuffer()

Returns:

(nullable): The GstGL.GLFramebuffer in use by this self

Return type:

GstGL.GLFramebuffer

New in version 1.24.

process_textures(outbuf)

Parameters:

outbuf (Gst.Buffer) – output GstBuffer

Returns:

whether processing of textures succeeded

Return type:

bool

Perform processing required and call #GstGLMixerClass::process_textures(). Intended for use within implementations of #GstGLMixerClass::process_buffers().

New in version 1.24.

do_process_buffers(outbuf) virtual

Parameters:

outbuf (Gst.Buffer) –

Return type:

bool

Perform operations on the input buffers to produce an output buffer.

New in version 1.24.

do_process_textures(out_tex) virtual

Parameters:

out_tex (GstGL.GLMemory) –

Returns:

whether processing of textures succeeded

Return type:

bool

Perform processing required and call #GstGLMixerClass::process_textures(). Intended for use within implementations of #GstGLMixerClass::process_buffers().

New in version 1.24.
