  GStreamer | gst-plugins-good | Ver: HEAD CVS
           Summary: [avimux] full and fast recording
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

Steps to Reproduce:

linux:
gst-launch-0.10 v4l2src num-buffers=200 ! "video/x-raw-yuv,
format=(fourcc)YUY2, width=640, height=480, framerate=(fraction)20/1" ! queue !
avimux name=mux alsasrc buffer-time=500000 provide-clock=1 num-buffers=10 !
"audio/x-raw-int, rate=44100, channels=2" ! queue ! mux. mux. ! filesink
location=record.avi

win32: (you need to apply the dshowvideosrc patch from bugzilla in plugins-bad
section, in order the choice the video size and framerate)
gst-launch-0.10 dshowvideosrc num-buffers=200 ! "video/x-raw-yuv,
format=(fourcc)YUY2, width=720, height=576, framerate=(fraction)25/1" ! queue !
avimux name=mux dshowaudiosrc buffer-time=500000 provide-clock=1 num-buffers=10
! "audio/x-raw-int, rate=44100, channels=2" ! queue ! mux. mux. ! filesink
location=record.avi


Expected Results:

When playing back, the video is jerky and video/audio are not synchronized.


Additional Information:

It's works fine when replacing dshowaudiosrc (alsasrc),  by the audiotestsrc
element (but provides only one channel).

You need a good hard-disk to record the big flow that the pipelines generates.
You can try first by replacing the videosrc, by the videotestsrc element to
test your hard-disk.
