Parses the input data into valid frames as defined by subclass
which should be passed to gstbase.base_parse.BaseParse.finishFrame.
The frame's input buffer is guaranteed writable,
whereas the input frame ownership is held by caller
(so subclass should make a copy if it needs to hang on).
Input buffer (data) is provided by baseclass with as much
metadata set as possible by baseclass according to upstream
information and/or subclass settings,
though subclass may still set buffer timestamp and duration
if desired.
