Class Details¶

class GstGL.GLUpload(**kwargs)¶

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

GstGL.GLUpload is an object that uploads data from system memory into GL textures.

A GstGL.GLUpload can be created with GstGL.GLUpload.new()

classmethod get_input_template_caps()[source]¶

Return type:: Gst.Caps

classmethod new(context)[source]¶

Parameters:: context (GstGL.GLContext) – a GstGL.GLContext
Returns:: a new GstGL.GLUpload object
Return type:: GstGL.GLUpload

get_caps()[source]¶

Returns:

in_caps:: the input Gst.Caps
out_caps:: the output Gst.Caps

Return type:

(in_caps: Gst.Caps, out_caps: Gst.Caps)

perform_with_buffer(buffer)[source]¶

Parameters:

buffer (Gst.Buffer) – input Gst.Buffer

Returns:

whether the upload was successful

outbuf_ptr:: resulting Gst.Buffer

Return type:

(GstGL.GLUploadReturn, outbuf_ptr: Gst.Buffer)

Uploads buffer using the transformation specified by GstGL.GLUpload.set_caps() creating a new Gst.Buffer in outbuf_ptr.

propose_allocation(decide_query, query)[source]¶

Parameters:

decide_query (Gst.Query or None) – a Gst.Query from a decide allocation
query (Gst.Query) – the proposed allocation query

Adds the required allocation parameters to support uploading.

set_caps(in_caps, out_caps)[source]¶

Parameters:

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

Returns:

whether in_caps and out_caps could be set on self

Return type:

bool

Initializes self with the information required for upload.

set_context(context)[source]¶

Parameters:: context (GstGL.GLContext) –

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

Parameters:

context (GstGL.GLContext) –
direction (Gst.PadDirection) –
caps (Gst.Caps) –
filter (Gst.Caps) –

Return type:

Gst.Caps
