            Bug ID: 797084
           Summary: "gaps in prefill mode" appear with splitmuxsink 29.97
                    FPS
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

Pipeline:
gst-launch-1.0 -v videotestsrc !
video/x-raw,width=1280,height=720,framerate=30000/1001 ! queue ! videoconvert !
avenc_prores ! queue ! splitmuxsink name=m muxer="qtmux reserved-prefill=true
reserved-max-duration=4000000000" max-size-bytes=0 max-size-time=4000000000

audiobuffersplit output-buffer-duration=1001/30000 strict-buffer-size=true  !
queue ! m.audio_%u

When finalising the second fragment, it complains that "can't support gaps in
prefill mode". Looking at the qtmux logs, the audio pad is a late stream by
0:00:00.033366667 (the duration of one audio buffer). Looks like the ends of
the video and the audio streams are not aligned properly in splitmuxsink, and
the first fragment ends up containing one extra audio buffer.

Attaching qtmux:6,splitmuxsink:6 log.
