stk_start_stream can only be called successfully if stk_initialise and stk_setup_format are called before. When using e.g. cheese it was observed that stk_initialise and stk_setup_format have not been called before which leads to no picture in that software whereas other tools like guvcview worked flawlessly. This patch solves the issue when using e.g. cheese.
