GstGLUpload *
gst_gl_upload_new (GstGLContext *context);

Parameters

context

a GstGLContext

 

Returns

a new GstGLUpload object

void
gst_gl_upload_set_format (GstGLUpload *upload,
                          GstVideoInfo *in_info);

Initializes upload with the information required for upload.

Parameters

upload

a GstGLUpload

 

in_info

gst_gl_upload_get_format ()

GstVideoInfo *
gst_gl_upload_get_format (GstGLUpload *upload);

Parameters

upload

a GstGLUpload

 

Returns

The GstVideoInfo set by gst_gl_upload_set_format().

[transfer none]


gst_gl_upload_perform_with_data ()

gboolean
gst_gl_upload_perform_with_data (GstGLUpload *upload,
                                 GLuint *texture_id,
                                 gpointer data[GST_VIDEO_MAX_PLANES]);

Parameters

upload

a GstGLUpload

 

texture_id

the texture id to upload into.

[out]

data

where the downloaded data should go

 

Returns

whether the upload was successful
