VideoScale Element with Bilinear Method issue (freezes when image blank)

[GoogleCodeExporter]

  source = ElementFactory.make("souphttpsrc", "Source");
        demux = ElementFactory.make("multipartdemux", "Depay");
        decoder = ElementFactory.make("jpegdec", "Decoder");
        videoscale_elem = ElementFactory.make("videoscale", "videoscale_elem");
        videocolorspace_elem = ElementFactory.make("ffmpegcolorspace", "Colorspace");

pipe = new Pipeline("pipeline");

        videoscale = ElementFactory.make("capsfilter", "videoscale");

   videoscale.setCaps(Caps.fromString("video/x-raw-yuv, width=" + videoSize.width + ", height=" + videoSize.height));
 pipe.addMany(source, demux, decoder, videoscale_elem, videoscale, videocolorspace_elem, videosink);
        Element.linkMany(source, demux);
        Element.linkMany(decoder, videoscale_elem, videoscale, videocolorspace_elem, videosink);

        this.demux.connect(new Element.PAD_ADDED() {

            @Override
            public void padAdded(Element element, Pad pad) {
                pad.link(decoder.getStaticPad("sink"));
            }
        });

        Pad p = new Pad(null, PadDirection.SRC);
        source.addPad(p);

What is the expected output? What do you see instead?

Video works fine under normal conditions but when pitch dark or extreme glare 
the pipeline freezes. Default videoscale properties as one can see from the 
code above.

Have you tried to verify this is a gstreamer-java specific issue, and not a
problem with the gstreamer framework itself?
No. Will do soon.

What version of the product are you using? On what operating system?
Ubuntu 10.04, gstreamer-java 1.5

Please provide any additional information below.

Ok I verified. This is an issue with the Gstreamer itself. Its nothing to do 
with videoscale. 

 $ gst-launch souphttpsrc location="http://user:@192.168.1.90/moxa-cgi/mjpeg.cgi" ! multipartdemux ! jpegdec ! ffmpegcolorspace ! autovideosink

Will file bug in gstreamer
