+# This test muxes DVB subtitles twice into Matroska: Once normally
+# and once with durations derived via the setts filter. Said filter
+# sets the duration for every packet except the last it receives.
+# The "-t 20" also tests that the BSF is properly flushed even
+# when processing ended due to something else than the input's EOF.
+# Notice that the last packet of stream 0 before 20s is present,
