# 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
# option is set and more than enough space has been reserved in advance.
