qtdemux error: streaming stopped, reason not-linked

[Joel Zhou]

Hi all,

I'm trying to use gst-launch pipeline to play mp4 video, but get a
not-linked error.

arm-linux-gnueabi-gst-launch-1.0 filesrc location=/share/lucy.mp4 ! qtdemux
name=demux  demux.video_00 ! queue ! hantrovdec srcwidth=640 srcheight=480
dstwidth=640 dstheight=480 ! mylcdsink

Setting pipeline to PAUSED ...

I also try it with more debug message, the output is in the following
pastebin link.
