Introduce gst_element_request_pad_simple
The name gst_element_get_request_pad()
is confusing to people
learning GStreamer. gst_element_request_pad_simple()
aims at
providing the exact same functionality, while making it more
explicit it is a simplified gst_element_request_pad()
.
gst_element_request_pad_simple()
is consistent with other
functions such as gst_element_seek_simple
.
This MR deprecates gst_element_get_request_pad()
so that a
compilation warning is emitted when used and incite developers
to use the more explicit gst_element_request_pad_simple()
.
