I want record a mp4 video with GStreamer,using this gst-launch command:
"gst-launch v4l2camsrc device=/dev/video0 !
video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! dspmp4venc !
hantromp4mux ! filesink location=blah.mp4 " on the N900. 
    but a error occured:
-------------------------------------------------------------------
New clock: GstSystemClock 
WARNING: from element /GstPipeline:pipeline0: Internal GStreamer 
error: 
clock problem. please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info: 
gstbin.c(2224): gst_bin_do_latency_func (): /GstPipeline:pipeline0: 
Failed to configure latency of 0:00:00.000000000 
-------------------------------------------------------------------
In the file gst-plugins-bad-0.10.15/tests/examples/gst-camera-perf.c,there is a
introduction how to record video and picture on maemo, but "dspmpeg4enc" can
not be found, so I use "dspmp4venc" instead, and the muxer is hantromp4mux or
ffmux_mp4, but the error appeared. and the recorded video file can not be
played in N900. so I want to know how this happened. 
  only this way can record video efficient, how can I record a mp4 vidoe
correctly with dspmp4venc and hantromp4mux (or ffmux_mp4).
  thank you very much.
