Class Details¶

class GstGL.GLViewConvert(**kwargs)¶

Bases:: Gst.Object
Abstract:: No
Structure:: GstGL.GLViewConvertClass

Convert stereoscopic/multiview video using fragment shaders.

classmethod new()[source]¶

Returns:: a new GstGL.GLViewConvert
Return type:: GstGL.GLViewConvert

New in version 1.6.

fixate_caps(direction, caps, othercaps)[source]¶

Parameters:

direction (Gst.PadDirection) – a Gst.PadDirection
caps (Gst.Caps) – the Gst.Caps of direction
othercaps (Gst.Caps) – the Gst.Caps to fixate

Returns:

the fixated Gst.Caps

Return type:

Provides an implementation of GstBase.BaseTransform.do_fixate_caps()

New in version 1.6.

get_output()[source]¶

Returns:

a Gst.FlowReturn

outbuf_ptr:: a Gst.Buffer

Return type:

(Gst.FlowReturn, outbuf_ptr: Gst.Buffer)

Retrieve the processed output buffer placing the output in outbuf_ptr.

New in version 1.6.

perform(inbuf)[source]¶

Parameters:: inbuf (Gst.Buffer) – the GstGL.GLMemory filled Gst.Buffer to convert
Returns:: a converted Gst.Buffer or None
Return type:: Gst.Buffer or None

Converts the data contained by inbuf using the formats specified by the Gst.Caps passed to GstGL.GLViewConvert.set_caps()

New in version 1.6.

reset()[source]¶: Reset self to the default state. Further operation will require setting the caps with GstGL.GLViewConvert.set_caps().

New in version 1.6.

set_caps(in_caps, out_caps)[source]¶

Parameters:

in_caps (Gst.Caps) – input Gst.Caps
out_caps (Gst.Caps) – output Gst.Caps

Return type:

Initializes self with the information required for conversion.

New in version 1.6.

set_context(context)[source]¶

Parameters:: context (GstGL.GLContext) – the GstGL.GLContext to set

Set context on self

New in version 1.6.

submit_input_buffer(is_discont, input)[source]¶

Parameters:

is_discont (bool) – true if we have a discontinuity
input (Gst.Buffer) – a Gst.Buffer

Returns:

a Gst.FlowReturn

Return type:

Gst.FlowReturn

Submit input to be processed by self

New in version 1.6.

transform_caps(direction, caps, filter)[source]¶

Parameters:

direction (Gst.PadDirection) – a Gst.PadDirection
caps (Gst.Caps) – the Gst.Caps to transform
filter (Gst.Caps) – a set of filter Gst.Caps

Returns:

the converted Gst.Caps

Return type:

Provides an implementation of GstBase.BaseTransform.do_transform_caps()

New in version 1.6.
