  GStreamer | gst-plugins-good | Ver: 0.10.6
           Summary: avimux muxed audio and video out of sync
           Product: GStreamer
           Version: 0.10.6
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: roadrunnerswife at users.sourceforge.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Please describe the problem:
avimux doesn;t correctly mux audio and video

Steps to reproduce:
ggst-launch-0.10 videotestsrc num-buffers=250 !
'video/x-raw-yuv,format=(fourcc)I420,width=320,height=240,framerate=(fraction)30/1'
! timeoverlay ! queue ! mux. audiotestsrc num-buffers=440 ! audioconvert !
'audio/x-raw-int,rate=44100,channels=2' ! queue ! mux. avimux name=mux !
filesink location=test.avi

ffplay test.avi



Actual results:
Shows that the video is played at half its rate and the audio start cracking
(buffer underruns?). Windows media player the audio is good but drifts apart
from video at a factor 2 (only visible with real content).

Expected results:
Video should display in image timestamps that folow the normal second clock

Does this happen every time?
yes

Other information:
When ONLY video is muxed it is ok.

When playing the file with gstreamer it is ok.
