Change get_context_info() into a set_context_info() function that initializes common defaults into the base class, thus allowing the subclasses to specialize the context info further on. The set_context_info() hook is also the location where additional context specific data could be initialized. At this point, we are guaranteed to have valid video resolution size and framerate. i.e. gst_vaapi_encoder_set_format() was called beforehand.
