qtdemux error: streaming stopped, reason not-linked

[Joel Zhou]

Hi Amit, DeepakRohan,

I replaced video_00 with video_0, but the error is similar.
I think it is the problem of "caps". Any idea how to debug it?

arm-linux-gnueabi-gst-launch-1.0 filesrc location=lucy.mp4 ! qtdemux
name=demux  *demux.video_0* ! queue ! hantrovdec srcwidth=640 srcheight=480
dstwidth=640 dstheight=480 ! mylcdsink -v
