+# 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).
+# (-ss 1.09 ensures that a video frame has the lowest dts of all packets;
+# yet there is an audio packet with the overall lowest pts. output_ts_offset
+# makes the pts of the audio packet, but not the leading video packet negative
+# so that we run into the above issue.)

# This tests writing the MS-compatibility modes V_MS/VFW/FOURCC and A_MS/ACM.
# It furthermore tests writing the Cues at the front if the cues_to_front
