Set if the nature of the format or configuration does not allow (much)
parsing, and the parser should operate in passthrough mode (which only
applies when operating in push mode). That is, incoming buffers are
pushed through unmodified, i.e. no #GstBaseParseClass.handle_frame()
will be invoked, but #GstBaseParseClass.pre_push_frame() will still be
invoked, so subclass can perform as much or as little is appropriate for
passthrough semantics in #GstBaseParseClass.pre_push_frame().
