+# This tests the scenario like tickets #4536, #5784 where
+# the first packet (with the overall lowest dts) is a video packet,
+# whereas an audio packet to be muxed later has the overall lowest pts
+# which happens to be negative and therefore needs to be shifted.
+# This is currently buggy (the timestamps of the video frames muxed
+# before the first audio frame are not shifted).
+# Also tests muxing DOVI.
