Don't give error if exporter not present.
If no frame is recorded for the VideoCreator (empty video), the close of the stream throws an error (java.lang.RuntimeException: error Operation not permitted, failed to write trailer to...). We should catch it.
If the vehicle is not known (no VehicleType available) don't give error on Replay on MRA.
Updated version to final.
