This is the problem:

gstffmpegdec.c(2010): gst_ffmpegdec_chain (): /pipeline0/ffdec_mpeg40:
ffdec_mpeg4: input format was not set before data start

At the very minimum you need a typefind element in front of ffdec_mpeg4, so
that caps are set on the incoming buffers, so that ffdec_* knows which format
it is.

If this is a raw video bitstream that is not in a container, you might need a
parser in front of ffdec_mpeg4 as well, but I am not sure if we even have a
parser for this.

In general, it's better to put MPEG-4 content into a container and then use
demuxer ! ffdec_mpeg4.

If playbin/decodebin play it, check what elements it is plugging
(gst-launch-0.10 -v will tell you the element names when the caps change).

Also check the gstreamer-devel mailing list for additional support.
