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