12 Usage: element-maker [OPTIONS] ELEMENT_NAME BASE_CLASS
13 Create a GStreamer element that subclasses BASE_CLASS.
15 --help Print this information
16 --prefix PREFIX Use PREFIX instead of "gst"
17 Example: 'element-maker my_element basetransform' will create the files
18 gstmyelement.c and gstmyelement.h that implement GstMyElement, a
19 subclass of GstBaseTransform, as an element named myelement.
