With pre-2.0 Intel drivers in CBR mode, if an explicit SEI message with the old (now deprecated) type is not included, the driver generates and inserts some timing SEI which is almost certainly invlaid. Before 7a4fac5e91789b73e07bd4ad20493cfde028df76 we always inserted our own SEI so this would not be visible, but since then it has been possible to disable that. We would also like to avoid using the deprecated type, and using the new type, while working in old drivers, does not suppress the spurious message like the old type does. Therefore, suppress the bad SEI insertion by providing a zero-length buffer with the old type, which the driver can insert harmlessly.
