Class Details

class GstGL.GLBaseFilter(**kwargs)

Bases:

GstBase.BaseTransform

Abstract:

No

Structure:

GstGL.GLBaseFilterClass

GstGL.GLBaseFilter handles the nitty gritty details of retrieving an OpenGL context. It also provided some wrappers around GstBase.BaseTransform's start(), stop() and set_caps() virtual methods that ensure an OpenGL context is available and current in the calling thread.

find_gl_context()

Returns:

Whether an OpenGL context could be retrieved or created successfully

Return type:

bool

New in version 1.16.

get_gl_context()

Returns:

the GstGL.GLContext found by self

Return type:

GstGL.GLContext or None

New in version 1.18.

do_gl_set_caps(incaps, outcaps) virtual

Parameters:

• incaps (Gst.Caps) –

• outcaps (Gst.Caps) –

Return type:

bool

do_gl_start() virtual

Return type:

bool

do_gl_stop() virtual
