There are two problems about this here. First of all, gdkpixbufdec
apparently only supports decoding the very first frame it receives and
ignores all future data as you noticed. This is also not fixed in newer
versions of GStreamer but should be rather simple to fix.
Can you file a bug here about that?

The second problem is that this way your frames would have no
timestamps. Something inside the pipeline would have to timestamp the
data. You could set caps with a framerate on multifilesink, then other
video/image decoders (e.g. jpegdec) at least would timestamps the
frames accordingly. This would have to be done for gdkpixbufdec too and
should be mentioned in the above bug report.
